RS3 Master Cylinder Upgrade Kit 1K1698001HS

Description

If you have installed a big brake kit, complete the package with our RS3 master cylinder retrofit kit!

The stock master cylinder is designed for effective use on the stock brake calipers, but it can fall short when used with a 4-piston upgrade kit. The larger RS3 master cylinder can handle the higher volume needs of these calipers, improving the pedal feel and brake response.

This kit does require modification to your stock brake fluid reservoir, or requires the purchase of a new reservoir, which will come modified and ready to install.
