Porsche Brembo 996 BBK conversion

[Lavatoad]

looking like I may source some front calipers from freakyparts. where is everyone sourcing their rear 996 calipers from?

I took a chance with ebay. They were in much worse shape than advertised. Ended up replacing all seals, hardware, and pistons. Biggest pain was sourcing everything during the peak of covid supply chain issues. Probably easier now.

EC stands for extra clearance.

[Albino09]

The clearance is an ARC-8 problem right? I bought 18x9.5 ET35 EC-7s and I want to be clear (no pun intended) these wheels should be OK at that offset.

[Lavatoad]

Do you have ARC-8s? If so, how much clearance do you have between the spokes and the calipers?

Yeah ARC-8. With the 5mm spacer, I have 2-3 mm of clearance.

How are folks with apex 9.5" et35 wheels managing with he wheel poke on spaces? When I mount my 18x9.5 et35 with a 5mm spacer (to clear the brakes) I'm getting a lot tire extension past the fender. Enough to make me concerned about contact under full compression.

Still on stock suspension with camber pins pulled.

I wouldn’t have gotten rid of my ET22 wheels had I known that 996 calipers would require a spacer up front lol. Also sucks bc I wanted to run -2.4° up front which isn’t possible with the current offset.

You can get 6 pots which will suit your car better anyway.

I wish I could have Brembo brakes. I don’t think I can’t have it with my wheels spec

[FCD46]

Yea, that would have been smarter, but I didn’t know that ~4 years ago when I put these brakes on and bought the wheels.

Same, I got 18x9.5 et35 on a 265.. had to put 10mm spacer to fit over the brakes. Punching the air, should’ve got the et22

[DoubleSidedTape]

But was that with the 12mm spacer such that the wheel was 9.5et23? Most run 9.5et22 with 265 tire and -3 to -3.5 camber.

Begs the question - why not just get the typical 9.5et22 wheel which would then negate need for spacers up front AND in the rear, and you could still rotate front to rear.

With a 275/40/17 Falken RT660 tire I needed more than 3 degrees of camber and a decently high ride height. With a 255/40/17 RS4 tire it’s more like two.

Or run a 255 tire or a narrower 265 tire (as in, not michelin)

If you're on stock suspension, you won't have much neg camber while static (so it'll look like lots of poke), but because of your ride height, when the front compresses, the camber will go more negative, and should clear the fender fine on 9.5et30.

In most cases camber, more of it.
