Looking to update your Supra's interior? We have just the thing! Many options are available, including synthetic or genuine leather and stitching colors. Includes both sides!

Please keep in mind these are made to order, so you can expect a few weeks wait time for them to be finished up and shipped out. We also cannot 100% color match to your interior. Every car has had a different amount of use/wear, exposure to UV, chemicals, etc., so we are unable to get it exactly the same as what you have. The color swatches are the different options we have. If matching colors is a concern, we recommend getting all of the interior options we offer at the same time, including front/rear seats, door arm rests, center console, and shift boots.

Power gains of up to 100hp on a stock vehicle without the risks of flashing!

Units shipped 3/5/2021 or later include a free electronic wastegate (EWG) connector preinstalled in the JB4 harness!

The JB4 is the most advanced and highly featured tuning system available for your Toyota Supra Mk5. Power gains are up to 80hp to the wheels (100hp crank) on a completely stock car on pump gas for a B58, gains with bolt-on parts, higher octane, E85 mixtures, and larger turbos are even higher.

The JB4 features a simple plug and play installation harness for easy installation & removal and includes many features not found with any other tune. Including on the fly in dash map switching between factory and various performance maps, optional in-dash gauge displays for boost, boost limiting by gear for improved traction in lower gears, progressive water/methanol support, built-in data logging, built-in code reading, optional direct EWG control to prevent throttle closure with exhaust modifications, exhaust flapper control, and much more. Other more expensive tuners may claim to equal the JB4's technology but upon closer examination lack most if not all of the JB4's features.

Remember the JB4 does not require any additional modifications or previous stages. Simply install the JB4 as your first and only modification and enjoy an entirely new fast and smooth racing experience. The JB4 also does not require any user setup or customization but for those who are interested in logging, adding new features as we post them, etc, we suggest the BMS DATA cable or REV3 mobile phone adapter.

Note we have not developed the in-dash commands yet for the JB4 Supra. Until then a JB4 mobile adapter or BMS data cable is required for any map and setting changes.

Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit, or to your Windows laptop with the BMS data cable. Both options allow you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development. Separate JB4 Mobile app purchase also required.

We are proud to release our in house high flow catalytic converter for the 1986.5 to 1992 Toyota Supra with 7MGE or 7MGTE engine, in 3" diameter! This is a true flanged bolt-on design which is a direct replacement for the factory CAT as you can see in the photo. Expect an increase of ~5% in power and a quicker turbo spool. These are bolt in versions. We also sell the weld in version in the downpipe/exhaust section. We use stainless for these, as shown. These are 49 state legal. Not legal in California. 

You will need to measure your existing cat to make sure we send you the right version, either 11 inches or 12 inches. Please let us know at the time of ordering the measurement yours is, as these are made to order in each case.

Please note that the gaskets are not included, but very easy to find and source locally.

*Various differentials or transmissions need the smaller or larger bolt pattern, so please measure on your actual transmission and/or differential flange. 

This U-Joint Adapter is the perfect solution for adapting your Toyota 3-bolt differential flange (Supra, GS, SC) to a driveshaft utilizing a 1350 4-bolt U-Joint flange.

Includes all necessary hardware for ease of installation.

This product is also compatible with the Aristo A340E output flange. 

Please note there are 2 different flanges, "big flange" and "small flange".

The "Small Pattern" bolt holes measure approximately 90.5mm center to center, from one hole to another (3.57")

The "Large Pattern" bolt holes measure approximately 99.5mm center to center, from one hole to another (3.91")

Please check with us for availability, as it may take about 1 week for your adapter to ship out.

Switching over to a single turbo? Still have ugly heater hoses running over your valve cover? Clean up your MkIV A80 Supra engine bay with this hose kit from PHR! Comes with four stainless worm gear clamps to ensure a leak free install.

Finally an overflow you can be happy to have in your engine bay! The PHR Radiator Overflow for the MKIV Supra tucks in close the the headlight, making room for 4" intercooler piping or a full size battery to fit up front (PHR will soon be offering a battery tray to fit a group size 26 battery, stay tuned). No more tucking ugly plastic overflows and pretending it's not an eyesore. The PHR overflow features a CNC Formed aluminum tank body with a billet cap. Please keep in mind this MkIV Supra chassis specific fitment. It is not meant for similar chassis' (SC300/Soarer) without modifications.

Installation notes:

Hose from radiator should attach to the bottom port on the overflow tank. The top port can just vent or can have a spillover hose run underneath the vehicle. If running hose please do not let the spillover drain in front of the tires.

The PHR Radiator Overflow is not designed for use with a OEM size (Group 24) battery or the OEM battery tray. The PHR Radiator Overflow is perfectly paired with a PHR Billet Battery Tray or PHR Battery Relocation Kit. If you would like to retain a OEM size battery, you will need a new battery tray.

When looking for a Limited Slip Differential  XAT Racing always goes with Active Tracking Service - better known as ATS or even carbonetics.  These LSD kits are available in 1.5 way or 2 way operation. Silent when taking tight corners so none of the metal on metal CLUNK CLUNK of many of the other brands of LSD kits.  

These kits ship directly from Japan -  So please expect a shipping rate of about 165 dollars on average to the lower 48 states. We can ship worldwide as well on these.

By utilizing the CC composite discs, the ATS carbon LSD posses the superior transitional characteristics from free to differential lock, enabling control that feels quite natural.

Principal characteristics of the Carbon LSD

* Gentle transitional characteristics that yield ease of handling from free to lock
* Small degree of slipping which provide a greater flexibility
* Super durable
* Stable differential lock performance which is unaffected by oil temperature changes
* Quiet operation without chattering noise
* Very high adaptability to many LSD oils from different manufacturers

Important - it is very important to monitor the differential oil temperature to keep it under 150 C degree (302 F). Continued driving with the differential temperature above that point might cause the carbon chips peeled off.

For those that need more electricity than our 200 amp option can provide, we have teamed up with JS Alternators to offer these custom made to order options! Even better, theyre plug and play, no adapter wiring needed!

JS Alternators also requires their universal Big 3 wiring kit, or otherwise similar wiring upgrades in addition to the factory wiring in order to handle the higher output. The big 3 Wiring upgrade is an ADDITION to your factory wiring.
All factory connections need to remain connected. For protection, it is recommended to add an in line fuse to the positive wire. All grounds must be cleaned to bare metal and properly secured.

Big 3 wires are 1/0 gauge pure copper cables. 1 positive to connect from the positive stud on the alternator to the positive battery terminal. Other 2 ground wires go from the alternator mount bolt to frame/chassis, and negative on the battery to frame/chassis.

Most JS Alternators are custom built to order and typically take 5-15 business days to be built and shipped. All JS alternators have a lifetime warranty on labor, and 1 year warranty on parts.

Hairpin units are commonly called 6 phase. They produce more output at idle and are more efficient than a conventional alternator. JS Alternators hairpin units feature premium bearings to withstand high engine rpm and utilize dual plate rectifier with 12 heavy duty diodes for improved cooling. Hairpin Units are a more reliable alternator to withstand high heat, high demand for car audio, marine, and racing applications.

The PHR Billet Isolating Engine Mount is the ultimate solution without compromise. Full solid mount will always be accompanied by increased vibration and noise transfer. This innovative isolating design help cut down that transfer while keeping the rigidity that you want for your race engine. More aggressive than the TRD variation without committing to full solid mount. Despite the 2JZ being a very balanced engine, a full solid mount will always be accompanied by increased vibration and noise transfer. This innovative isolating design help cut down that transfer while keeping the rigidity that you want for your race engine. 

These are beautifully CNC-machined from 6061 aluminum with a 70A Durometer rubber cushion separating the two ends. You're going to shed a tear hiding this away in your engine bay.

Mount is serviceable meaning you can inspect and replace the rubber cushions inside. These can be purchased from PHR separately.

Price includes both mounts for both sides! THE SUPRA VERSION IS DESIGNED AROUND THE S1 (EARLY MODEL) ENGINE BRACKETS** SC300 and Late Model Supra Brackets (97+) will not work. If you have a 97+ Supra or any year SC300, you will need the billet mount brackets as well. The factory cast mount brackets have been discontinued.

These toe arms are essential pieces for racing applications. They keep your rear wheels locked in line without radial shimmy upon launch. In cornering they remove neraly all toe flex and add stability and predictability.

The PHR Toe Arms are constructed using swaged steel tubes, chromoly heim joints and 4130 Heat Treat spacer bushing and taper sleeve bushings.

Please note due to draconian laws, we are not able to ship these to a California address. Please support the RPM act.

Watch Andy show off his pipe. Impressive! With a girth of 3 inches, his pipe offered by hand will absolutely make you smile! This is an in house made XAT part, hand welded on a jig, and factory replacement fitment with no modification needed--for your pleasure.

You will need to measure your existing cat to make sure we send you the right version, usually either 11 inches or 12 inches roughly. Please let us know at the time of ordering what yours measures out to be. It is important to get the correct length the first time to avoid further issues.

What is a test pipe?

Simple. A test-pipe is used to replace the catalytic converter on cars to "test" if the cat as clogged or not and will verify for you. Simple bolt-in performance product with only 4 bolts (can be obtained at any hardware store if not reusing the factory ones). Excellent bang for the buck performance. Test pipe can be used with various downpipes for total CAT elimination (catalytic converter), or it can be used with a factory exhaust or aftermarket exhaust as well.

Please check your local laws, as this is intended strictly for off-road vehicles only. It is up to you to reinstall the cat when you are done using this. 

Fits both 6-speed (220mm) and automatic (200mm) differentials.

Powerhouse Racing Solid Front Differential Mounts (Ear Mounts) will firm up your rear end to be able to handle massive horsepower while reducing ET's and 60 FT times.

Don't waste energy shaking that differential around! Transfer that power through the differential, keep the rear end in place, and help eliminate wheel hop! A shaking rear end is a breaking rear end.

Precision CNC machined from billet 6061 Aluminum for perfect fit every time.

Please note: sold by the pair and only available in a Anodized Black finish.

MAY ALSO FIT Z30 SC300, SC400, SOARER, ARISTO, GS300, GS400, GS430, LS400, LS430, AND CENTURY. FITMENT NOT CONFIRMED, TEST FIT AT YOUR OWN RISK. We will not be able to accept returns on parts that are already test fit. 

The girdle kit includes required ARP hardware, and fits any 1JZ or 2JZ engine, GE or GTE! What is it for? A girdle will remove 'swing' in the main caps. The swing in the block will be most in the middle of the engine. The girdle will also act as a partial windage tray. This girdle is compatible with all 1J and 2J engines and all sump types.

If you are using the OEM main caps, the girdle will rest on them. Your engine shop/builder should machine the provided spacers to the exact same height. If using billet main caps, you can let the girdle kit have a tiny amount of space from the caps, but spacers may still require modification to fit.

We have confirmed fitment with Titan and Induction main caps. Some minor milling may be required on the caps as well as spacers to fit the girdle properly.

Since TRD has discontinued theirs, and Megan no longer sells any, factory Toyota might be the only way to go for your build! Quality solid mounts are readily manufactured by places like PHR, however these are not ideal for a car that rarely leaves the street. Please check availability with us before ordering

We don't always have a set in stock, so please reach out to us beforehand to verify wait times if you need a set posthaste. Price is for both sides

Please contact us for availability on the different rotor/caliper styles, as they go in and out of stock regularly!

We at XAT have developed an intermediary brake kit that slots just below the LS460 big brake kit that we sell! As we've discovered, the LS460 brake kit combo requires a minimum of 18" wheel, and some 18"s also will not fit. It's easy to recognize the fast growing popularity of JDM vehicles we grew up loving now being imported, as we have a hand in doing that as well!

This kit is specifically designed to use MkIV Supra TT rotors, meaning you only need 17" wheels to clear these brakes, giving an extra option for those looking to keep with period correct wheels and wheel sizes. Although we dont have a complete list of every wheel this kit will fit, if you suspect the LS460 kit may be too big for you, this is a terrific alternative, using OEM quality and Wilwood brand parts!

The steering arm and caliper may need to be modified on your setup to fit this brake kit, depending on application, if youre not using an angle kit. This had to be done on our zenki '89-92 UCF10 Celsior to fit, as well as our '96 Crown JZS155. Expect similar requirements on X90s and early X100s, likely on GS/Aristo as well. We have provided pictures of where we had to modify the caliper to fit.

Brackets fit:

☼ 1992-2005 Lexus GS300 / Toyota Aristo JZS147, JZS160, JZS161

☼ 1998-2000 Lexus GS400 / Toyota Aristo UZS160

☼ 2001-2005 Lexus GS430 / Toyota Aristo UZS161

☼ 1995-2005 Toyota Crown Majesta UZS151, UZS157, UZS171, UZS175

☼ 2001-2010 Lexus SC430 / Toyota Soarer UZZ40

☼ 1997-2017 Toyota Century V12 GZG50 

☼ 1989-2000 Lexus LS400 / Toyota Celsior UCF10/UCF11 and UCF20/UCF21

☼ 1993-2002 Toyota Supra

☼ 1992-2000 Lexus SC300

☼ 1992-2000 Lexus SC400

And possibly others!

If you are switching to an after market exhaust manifold on your 1JZ or 2JZ engine, then many of the manifolds require a shortened exhaust stud to provide proper fitment.

We have custom sourced genuine Toyota parts that do the job, and have included the correct nut for them as well.

You will receive:
☼ (8, 10, or 12) Exhaust Studs Genuine Toyota
☼ (8, 10, or 12) Nuts for exhaust studs genuine Toyota

We keep a set ready to ship out at all times! Please select the engine you have so we can send the correct quantity.

2JZ-GE, both VVTi and non, will need 8 nuts and studs
1JZ-GTE VVTi will need 10 nuts and studs
1JZ-GTE non-VVTi, 2JZ-GTE, non VVTi, and 2JZ-GTE VVTi will all need 12 nuts and studs

Need the reverse Torx socket in 3/8ths drive to remove the old ones and install the new? We can get that too!

The studs protrude 22mm (7/8") from the head flange when installed. In the pictures for representation, the longer, rusted studs are the factory 2JZGTE ones.

Please note these have been on backorder since March 2022, we have no realistic timeframe on when they will be available again. Toyota did fulfill an order for one at that time, but we have been waiting since then for them to be available again. Please do not buy this unless you are sure you are okay with waiting months or years

Factory new steering racks are no longer available for these cars, however Toyota themselves do offer rebuilt units! These racks are rebuilt by Toyota themselves and are the best option on the market. Don't waste time and money with cheap no-name rebuild kits, get original parts and another 25+ years out of your Supra!
