How about a brake bias valve off another car? We used to do this (a lot!) right or wrong back in the day for both the 914 and the 944.

since the car dives when you brake, roughly 70% of the car's weight is over the front tires during a heavy stop. this means that about 70% of the car's braking power is designed into the front brake system. if the rear brakes are too big, the rears will lock up well before the fronts (particularly if braking in corners). the potential for spins is very real. just ask pedro.  |
