Fits all Alfas that do performance driving. The stock Alfa proportioning valve is the weak link and should be replaced with a Tilton Unit.

This five-position manual lever type is installed inside the car. The link to the rear is rerouted inside the car to mount the lever.

The driver needs to reset the rear brake bias for different conditions. The object is to find a setting that prevents rear brake lockup on the most severe corner on the particular track.

Stock Alfa brakes come to life and pedal pressure is improved with the removal of the stock unit. Stock Alfa Calipers and Rotors are quite sufficient for racing. Our E Prod National championships 1750 Spider Veloce is required to run stock rotors and calipers. We have never had a problem with the stock system with a Tilton Proportion is valve.

Note: This Tilton 90-1000 comes with AN3 & 3/16" inverted flare (fittings included). Tilton PN 90-1003 is provided with 10mm x 1.0 threads (fittings not included).
