Too much can be as bad as too little...

FWIW.

I've worked with Brembo and this combo is designed to work with the factory master cylinder. This is also a very good combo when it comes to rotor ratio from front to rear, as well as swept area & pad size in relation to the weight of the 928. I think it's pretty safe to trust Brembo's input....

Sterling your car may behave differently than my race car but for me I found that after installing f50 fronts with 14" rotors my stock rears were still more than adequate. I'm currently using no brake bias at all.

mark and Joe both went this direction. I remember driving Joes car with the special master cylinder, guess what. after all that work , they went back to stock. balaicing front to rear, especially if you are fast with the car, will be pretty easy to do with the stock set up as well

remember, as your stopping iincreases, the more weight transfers to the front. you , could in most instances, have only a few hudred lbs on the rear wheels, maybe even less on the inside rear wheel of a trail braking turn. therefor it will take quite a bit of braking and driving skill and style change to have even braking bias or to increase the braking forces to the rear. interestingly, going with larger front brakes usually matches the increase weight transfer so that
having the stock brakes in the rear with modified brakes up front will usually work out pretty well, especially since in a street car, you have to run in the rain sometimes. more braking forces in the rear as a percentage forces available, could be a bad thing.

Go fast, stop fast!

How do you remove the brake bias?

Mark what dose a conversion like this cost?

another thing that comes into play is that I only have 9" fronts vs 12" rears that also affects this greatly since most of the racers are running 12's all the way around.

On your car it is a bias valve screwed into the ABS pump.

I think Carl at 928 Motorsports offers it. I was lucky enough to get mine for free from my sponsor back when i was racing
World Challenge.

This will be your limiting factor......with the power you have planned plus the weight of a street car, the 9" tire..say 255 will be working really hard for "at the limit" braking....

I have 18x10x65mm wheels all the way around with 275/645-18 race slicks....it barely clears the front on the outside and rubs a bit at full lock on the inside...but I only have slight fender rolling in front...basically a flat inner lip is it.... I'd say you can run larger up front no problem...

Wow, did not know I had ABS in MY 81

Seriously, on my '81.
