Fisch Racing Tech - Clutch Master Cylinder Adapter Kit Lexus IS300 / SC300 / Toyota Supra

Our Clutch Master Cylinder Adapter Kit is a direct-fit solution for installing a high-quality Wilwood master cylinder in your Lexus or Toyota. It's the perfect foundation for a manual transmission swap or for upgrading the hydraulics to match a performance clutch.

We engineered this kit to solve the problem of incompatible bolt patterns between the factory firewall and the proven Wilwood Master Cylinders. Our precision-machined billet aluminum adapter makes the conversion seamless and solid.

This isn't just an adapter; it's a complete solution designed for the builder.

Key Features:

• Perfect Fitment: Our CNC-machined 6061 billet aluminum adapter ensures a perfect, flex-free fit between the firewall and the Wilwood master cylinder.
• The Best Components: We pair our adapter with Wilwood master cylinders, known for their reliability and performance in motorsport.
• Engineered for Performance: An essential upgrade for cars with performance clutches that require more fluid displacement than the stock 5/8" master can provide. Ideal for manual swaps, ensuring you build it right the first time.
• Easy Adjustment: When you purchase a 5/8" or 3/4" master cylinder from us, we modify the pushrod by milling a 1/4" hex onto it. This exclusive feature allows for precise pedal height adjustment with a simple wrench, saving you time and frustration. Note: The 7/8" and 13/16" bore master cylinders comes from Wilwood with adjustment flats already on the pushrod.
• Complete Kit: Includes the adapter plate, mounting studs, lock nuts, and a high-quality clevis rod end with pin and cotter pin for a comprehensive installation.

Clutch Line Compatibility:

The included Wilwood Masters have a 3/8-24 outlet, which fits our Clutch Line. But it's very likely that it will not fit an OEM clutch line. Figuring out the clutch line fitment is the buyer's responsibility. 

Please note: Product photos show the 5/8" and 3/4" bore master cylinders. The 13/16" and 7/8" bore master cylinders are a remote reservoir style and will have a different appearance. See "Included Components" tab for Wilwood part numbers.

Finish your build with the confidence and quality it deserves. Get the reliable hydraulic solution your performance car demands.
