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:

1. Tilton master cylinder (3/4", 13/16" bore size available)
2. Grannas Racing Tilton "RHD" specific angled reservoir 
3. Cap, clamp, 3AN union fitting
4. Billet adapter bracket
5. Hardware/studs for installation

I 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!
