Weingart was correct that with a heavier front bias, the car should understeer more than oversteer, however, that is assuming that same level of braking force. With larger front brakes, the car is capable of braking harder, and under harder braking the weight transfers to the front even more (the nose-dive effect), which unloads the rear and makes it "skittish". So in both of you are right, just working with slightly different assumptions :) The reason a rear brake kit is not often offered is because of the weight transfer to the front under hard braking, which means the front tires would have the maximum traction. With bigger rear brakes, you will find that the rear brakes ABS would activate pretty easily under hard braking... I am leary of Stoptech's claim that their brake bias the same. If the bias is the same, and the rear brakes are kept the same, then the front braking would remain the same by definition. From what I read Stoptech's claim is actually that their brake system provides a "better" brake bias than other big brake kits. Brake bias can be easily adjusted using a brake proportioning valve. I got one installed and I was able to adjust the brakes (given I had the "big" R33 GT-R brembo brakes) to feel like the stock bias... BTW Harry, are you going to be in Japan around 15-20 July? :)
