For those Supra owners with an after market clutches (especially hydraulic throw out bearing clutches), especially those on 3 and 4 disc Tiltons (any clutch for that matter) and you suffer from a clutch master cylinder that is barely getting the job done, this is a great after market direct bolt-in solution.
Fits: MkIV Supra, SC300, SC400, and others
How do I know my clutch master cylinder is barely getting the job done? If engagement is nearly at the floor on your heavy duty aftermarket clutch, chances are you master cylinder is trying everything it can to produce the pressure to make the clutch engage/disengage, but it's struggling.
The guys at Twins have done all the engineering for you so swapping your OEM Toyota master cylinder for the Tilton master is plug and play. If you are considering this swap I can recommend it and if you decide to do it you are crazy not to get this setup, as it will make your life that much easier.
Remove the factory master cylinder and install the Tilton master cylinder with the adapter kit, so its a direct plug-n-play on the MKIV Supra, add oil, bleed the clutch and you're good to go.
This will improve clutch pedal action, travel, engage/disengage on any after market clutch assembly and is mandatory on any after market clutch that uses a hydraulic throw out bearing on their twin, triple and quad disc units.
The kit will replace the factory 5/8” clutch master with a Tilton 3/4” master cylinder. This piece is mandatory for Tilton 4 disk users and highly recommended for Tilton 3 disk users.
Can also be used with other clutches with similar benefits.
Direct bolt on install. No cutting or drilling.
Uses whole stroke of pedal, not just the last % off the floor.
Faster shifting, clutch engages sooner.
More natural feeling pedal. Slightly higher pedal effort.
¾” bore master cylinder = more volume of fluid working slave cylinder
