18" wheels, sport brakes what offset?
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.

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... |

I'm actually looking at the 18x9.5 +38 though. Would give say.. 3mm more clearance... Wonder how close it was? |

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

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. |

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 |
:ugh2:

Of course itll work. x9 at et 15 is 6mm's narrower on either side of the rim then 9.5 et 15
|
Btw zoomzoom. Any particular reason why your only doing x9/x10? The car can fit more easy with the correct offsets and your intended camber settings. Also i prefer square wheel/tire sizes over stagger on the 370low for track

I wouldn't run +15 on offset (20mm spacer?) though, unless there's a reason to? If I understand correctly, the 18x9.5 +35 should clear just fine according to your data, so why run a spacer that would create clearance issues? You ran a 275/35 up front with no issues? That definitely simplifies things. |
I run with RPF1 18'' 9.5 +15 square setup on a 275 tire.
the rear is perfect and the front you will need to run with a lot of camber or narrow tire. I had to roll my front fender to make sure it doesnt rub ! they clear my AP BBK. the +38 in 9.5'' didnt clear the caliper edit; -2.7 camber http://www.the370z.com/members/megan...ure52932-a.jpg |
