(Disclaimer: I already asked this in the Wheels/Brakes section, and got 1 unhelpful response)


I have been wondering about the possibility of replacing the front brakes with the Stoptech setup (ok, nothing special here...)

However, I have read that people who have done this have had severe overheating issues with their rear pads.

How possible is it to take the front discs and calipers and put them onto the rear?

Is this a good idea? Are the bolt patterns compatible?

the one response I got in the other thread mentioned the brake bias, but the full 4-wheel kit supposedly has great bias balance, so I don't think this would be an issue... but let me know what you guys think.

 

YOu can't do the front to rear disc caliper swap. For starters the rear disc has the parking brake drum built into it which is not in the front disc so the design is completely different. Furthermore the bolt pattern for the front caliper is different and the pistons are way to large to use on the rear.

 

This may be true when runing hard on the track, but it should not be true for street driving. Putting larger brakes on the front while leaving the rears stock moves the bias to the front and uses the rears less.

If you're running laps and you upgrade the fronts you'll want to upgrade the rears because without time to cool down the smaller rears can overheat.

That would be true if StopTech didn't sepecifically balance their front kit to work properly with the stock rears. As a result, to answer the original poster, it wouldn't be a good idea to move the stock fronts to the rear, as the larger piston and rotor size would adversely affect balance.

thanks for the info; I was thinking specifically about track usage. In any case, I thought I had come up with a clever solution to a problem I have heard about, but apparently not. eh.

 

You can always remove the rear parking break...

If you were to put the Front calipers / Rotors in the rear then the brake bias will be too close to being equal...


Even with the stop tech 355mm all around (14.1" set up) with 4 pot up front and 4 pot rear... the brake bias is more to the front... So much infact the rear calipers for this brake kit use a different pad size that no performance friction pads are made available for...
