What overall weight of car has to do with that? Only regarding heat capacity of brakes / how long one can do track sessions if used on even lighter car then donor. Bias is one (rest of car, especially tires/weight distribution/aero) that will affect how safe/stable/predictable car stays at heavy braking/lockup/treshold braking, how short are braking distances (if one end of car is not underbraked). And that optimum is specific to specific cars of specific weight distribution and specific suspension design. WRX has different weight distribution. Suspension has many similarities, but is NOT identical. Car maker (and proper BBK vendors) engineers spent lot of time on fine-tailoring best bias, and at different scenarios. Many many times more then enthusiasts can afford testing for limited time on limited scenarios.
If argument of donor car weight vs weight of car brakes will be retrofitted to holds any meaning and should be main deciding factor .. just install brakes from eighteen-wheeler trucks and go right to track, as probably that will be best BBK possible  |
This is all a stupid argument. The manufacturer did extensive testing of every possible component in the drivetrain and suspension system and they came up with the EXACT SAME BRAKES AS A TOTALLY DIFFERENT (HEAVIER) CAR IN THEIR LINEUP. Bull$hit. They did it because they already had the parts and they were close enough to work well.
Car A has front brakes A, bias A and weight distribution A. Car B has front brakes A, bias B and weight distribution B. If a brake manufacturer makes a kit to replace brake A it works on both car A and car B. As was pointed out above this kit makes a minimal change to bias. This kit is not a BBK. But it IS a huge weight savings off the front end of the car. If you need front brakes anyway and get everything stock you're looking at a couple hundred dollars. This kit is a reasonably priced replacement.
All the arguments being made should be against putting this kit on a WRX, those are pigs compared to a BRZ.
