Wilwood and brembos

[dsmpat95]

I just put them on my car. I have Wilwood 4 pistons dynapro calipers up front. And I'm running evo 8 brembos in the back. Just wondering if it will affect brake bias at all. I planning on doing autocross with my buddies evo. Autocross is new to me.

As long as the Wilwoods are setup properly for the stock proportioning valve then you'll be fine. Are you still running ABS? I prefer the feedback/feel of non-abs when running the larger brakes but maybe that's just me.

 

[dsmpat95]

No ABS.

The correct answer would be; it depends upon the specs of the rear calipers you have now, rotor size and pad in use. AND how that pairs with the front kit.

If the rear rotor is larger or the pistons larger (or both?) then you'll have more rear bias than before the rear kit was installed....or less front bias after the front kit was installed....or...you get the idea. Depend on what came first!

To know what the spec was and now is you'd need to know what changed. Both first, second and thirdly on the transformation.

I have no clue what these rear parts are about but if you get me the info I'll be happy to supply you comparative data on all of it.

Does no one else find it horrifying that people just bolt on brake parts without doing the math first? Or am I the only one?

I have the wilwoods and they are awesome.

Not really. It's market driven; everyone's looking for a bargain and not taking time to do it right. You can get to a streamlined format of the calculator on my web page 24/7.

Are you saying DSM'ers are cheap???!!! Never!

Sad if you ask me.

My front rotors are 12.19 diameter. My rears are 11.81 inches diameter. I have the pads from Wilwood up front and Posi-Quiet Pads on the rear. Sorry for the slow reply, had a cook out for the fight.

 

[Todd TCE]

How large is the rear piston??

 

[dsmpat95]

I would have to take the brakes off the car again. They are off a EVO VIII.

 

[dsmpat95]

I couldn't find the specs on the rear brakes on the web for the life of me.

 

[dsmpat95]

They are about 1.3 of inch in diameter. Just measured.

 

[Todd TCE]

So based on some quick input and some assumptions I read it at roughly 76/24 which is not all bad. I think if the car is AWD you could exploit a bit more rear still.

Thanks, you are the man. I hope this helps others on here too.

My main reason was the ease of the job. A bolt on application. I understand what your saying, but I have not even drove the car yet.

A quick look at some older stock data...find the car to be about 75/25 with the twin piston fronts in place on 10.75 F and 10.3 R rotors.

 

[dsmpat95]

In all, I'm not the far off the stock bias.

I was looking to do the same willwoods up front and evo brembos in the rear. I have the 6 piston fronts though.
