First let's address pedal feel on the BIG kits:

NONE of the BIG street kits available have good pedal feel, IMO. However, if a particular driver wants a soft pedal that translates into a cubic megaton of braking force, cool... I just pray they're not behind me when they hit the brakes in a panic stop.

I wish everyone on this forum could drive a car with a manual pedal box... it'd change the way we look at big brake kits and until that happens, I'm never going to offer any advice regarding brake manufacturers (since it'd be falling on deaf ears) and I encourage others who represent specific products to do the same.

Bias:
We don't have a good reference for bias because it's very difficult to compile a database of braking force for each kit. Some retailers have been contacted and asked to offer information for the purpose of compiling said database and the requests have gone either unanswered or rejected. However, based on what we know from other applications supported by the same manufacturers we can get a good guesstimate of the bias changes. The smaller Stoptech kits and the four-wheel kit, the smaller four-wheel Brembo kit and the smaller of the four-wheel Alcon kits all offer the best bias in terms of being closest to stock. Based off of BMW numbers, the smaller Alcon 4-wheel kit should have some additional rear bias which would be advantageous, IMO (if you want to go outside the box, Stoptech offers an ST-20 rear that I run on my car). If you're looking at just changing the fronts I'd encourage you to stay away from anything larger than a 332 rotor, or anything having large displacement calipers (i.e. large caliper pistons or calipers having more than 4 pistons). The larger you go, the less firm your pedal will be resulting in poorer modulation.

If you need me, I'll be getting my ass handed to me by Michael Gilati's yugo...
