Grannas Racing MKIV Supra Clutch Master Cylinder Upgrade Kit (also fits Lexus SC/GS)
This billet adapter and larger bore clutch master cylinder will allow you to do a simple bolt-in installation.
There are LHD and RHD specific versions of this kit, please choose accordingly. The MKIV Supra kit will fit both the MKIV Supra and the Lexus SC300 / Toyota Soarer. This is also available for the Lexus IS300 Chassis / Altezza / IS200, and the Aristo / GS300 / GS400 as well!
This kit includes the following:
- Tilton 75-series master cylinder (7/10", 3/4", 13/16", and 7/8" bore size available)
- Grannas Racing Tilton "RHD" specific angled reservoir
- Cap, clamp, 3AN union fitting
- Billet adapter bracket
- Hardware/studs for installation
We've tried to add some pictures to show the difference in size and mounting versus the stock RHD master. There is plenty of clearance for even stock twin turbo setups!
PLEASE NOTE: On some chassis where the clutch pedal uses studs through the firewall you will be required to remove/drill out the stock studs on the clutch pedal assembly.
Here is the recommended master sizes for the most common clutches I sell. This is all based on using a Tilton hydraulic release bearing with these clutches:
7/10 bore:
- OS Giken TR2CD, R3C or R4C
3/4 bore:
- Comp Stage2, 3 and 4
- Mcleod Single discs
- RPS Carbon clutches
- Tilton 7.25 Carbon clutches or OT-II metallic clutches
13/16 bore:
- McLeod Twin discs (RST, RXT, RXT1200)
- Tilton ST246 (both standard and HD version)
