18" wheels, sport brakes what offset?

Zoomzoom22 · 01-07-2013, 11:49 AM

I am looking to pickup some 18" wheels for track. It is not clear to me what offset is needed on 18" wheels to clear the sport package brakes. 19" wheels are not an option for me (tires are 18"). I need to pickup several sets of wheels 18x9 front and 18x10 rear but obviously don't want to be wrong.

Can anyone let me know what is needed in terms of front and rear offset?

wrong section, Id post this in the Wheels/Tires section. Those guys know everything about offset, most of us track guys dont use the stock sport brakes so.

The design of the spokes also plays a big roll on if the wheels will clear the calipers. One +35 offset 18x9 with a convex spoke design might clear while another with a concave design might not.

True.

I'm looking at RPF1's. I think their spoke design will clear the calipers just fine. Anyone know for sure yes or no?

Hopefully a mod moves this topic lol...

If you are talking about the RPF1 18x9 +35 then I think Mike has stated already they do not clear.

Wow, bummer.

I'm actually looking at the 18x9.5 +38 though.

Would give say.. 3mm more clearance...

Wonder how close it was?

Thanks for the link!

Maybe PF01's in 9.5 +15 will clear...

i have pf01, i used to run 18x9.5 et35 in the front and it clears no problem because the calipers no problem because of the spoke design. later i ran a 15mm spacer up front to make the et35 et15. Now im on Pf01s in 18x10.5 et38 with a 10mm spacer up front for suspension clearance, and still clears calipers

Sport calipers? Any other clearance issues?

Thanks response, I posed in wheels tires also.

Anyone know if TE37's will fit fine with +40mm. I assume so but thought to ask here.

Thanks on pf01. Hoping for something lighter but those can work if I can't find something.

yes sport package calipers.

18x9.5 et35 no issues, if you run et15 and a 275/35/18 tire then you better have a decent amount of front camber to not rub

Will be running 3 degrees negative in front with 3 way remote adjustables.
