You may want to run a 10mm in rear when you are running the ZCP setup to give the car nice balanced look.

gotcha but just as long as your running oem zcp's 8" with the 355mm, 4piston brembo.. i believe your fine with 15mm as we put that on fast eddies car like 3yrs ago. he had the identical setup your getting now. but yes, you can play it safe and just get the 18mm rather then the 15mm.

when using brembo 355mm or 380mm (4 piston)

csl wheels 8.5" require 10mm spacer
zcp wheels 8" require 15mm spacer
Thanks, great info here.
If this is true I think I'll just go 10 mm spacers all around!

Default Re: 4 piston brembo caliper clearance & ZCP rims

Hi all!

I found this thread, but not the answer I was looking for, so let me dig it out a little.

My problem : I have a BMW Performance front BBK and ZCP OEM wheels. In order for the wheel to clear the caliped, I had to use 10mm spacers, but it barely clears it (maybe 1 - 2 mm).
I guess I can get a name card to fit between caliper & spokes, but nothing more.

Here is a picture of my setup :


Do you think a very tight clearing is enough? Or should I use wider spacers?
My biggest concern is that the rim is not completely stiff and that the caliper might extend because of heat.

Any input is appreciated!

Use an 18 or even 20... that way you know you clear AND it looks ALOT better.
