Wilwood 295MM Kit Bias

[jules325i]

Currently building my race dedicated e30 with 15" wheels and have clarified that the 295mm kit fits with my wheels. And i'm going to upgrade the master cylinder.

Will this make the car very unhappy under braking with Stock rear brakes or
can it be made good with a bias valve.

Bump for an answer, running 84 318i with no abs using a 310mm ireland engineering kit.
Bought parts car with the kit, PO said thats the reason for his incident.

In terms of bias, the additional information needed would be the piston size and number of pistons in order to get a good ballpark of what's going on.

Jules, I've got all the maths for the actual bias. Just shoot me a reminder email. You too imitator.

I have heard claims that it doesn't affect the bias. From running a similar BBK, I can say from experience that it doesn't make the car unhappy except for ABS. It has absolutely no idea WTF is going on. Rebuilding my rear calipers helped tremendously to even things out, but without running more aggressive rear pads there will be some extra frontward bias. Not terrible mind you, but some.

Andrew, I would be curious to see the maths as well.

Dual 40MM piston fronts , and single piston 33MM rears

right arm!

Rough bias for 40/40 front with 33 rear is 74.61%/25.39% F/R. Stock e30 setup is 67.9%/32.1% F/R.

It is probably even higher when you consider rotor diameter differences.
