XAT Racing IS300 Full Front Brake Kit Crown Chaser Mark II Big Brake Kit LS460 Caliper Adapter X100 JZS151 JZS155 BBK

After the surprise success of our 2GS/SC430 brake adapters, we've started development on an IS300 version as well! These brackets let you bolt on 4 piston LS460 calipers to your IS300 / Altezza, making an inexpensive but VERY effective brake update option! Thanks to Toyota parts interchangeability, that means they also fit Chaser, Cresta, Crown, Mark 2, X90, X100, Progres, and VerossaX110 chassis'!

In our continuing support of Lexus performance products and the UZ platform, we have finished this set of brackets to mount 4 piston LS460 / LS600h brake calipers to any USDM IS300 2000-2005!

This kit is ideal for those DIYers that are looking for an inexpensive option for brake upgrades. You keep your factory brake lines in this bolt-on solution; all you need is a set of front 2007-2018 LS460, LS460L, LS500, or LS600h fixed 4 piston brake calipers, LS460 fitment pads, and a set of 2008-2014 IS-F14" rotors!

This kit includes everything you need for a full bolt on installation for your front brakes!

• Brand new Lexus OEM Calipers
• XAT Racing adapter mount brackets & hardware
• Roll center adjusters for bolt on installation
• Cross drilled rotors
• StopTech pads
• Stainless braided brake lines

Additionally, you will most likely need 18" wheels to fit over these. The only 18s we have found to not fit so far are some Enkei RPF1s and IS250/IS350 F Sport front wheels. We cannot make any promises on what else will not fit, however every other 18" wheel we have tried does fit over these brakes, including factory X-Runner wheels, Enkei NT03+, G35 Ray's wheels, etc.

Please also note these will fit the S150 series hardtop Crown, not the Crown Majesta. The Majesta JZS155 will use our GS300 adapter brackets
