15in wheels + lowering springs =Rubbing??

Let’s try this here instead....

Wanting to run 15x9 Forgestar F14s with 275-60-15 MT S/S on my 2015. I’ll have Baer brakes. Someone said not to go above 15x9.33. So 9 should work right? Asking because of the lowering springs, I use eibach pros 1” drop.


[MENTION=10926]beefcake[/MENTION]....your thoughts? You race these cars.

Wow 15s are real small and you'd have to have a ton of sidwall. I'm running 18x11s. I'm amazed 15s clear even the regular base brakes.

They don't. You have to swap to drag brakes.

I have the needed brakes. I think 15s will help doing digs on the street. Replacement tires almost 50% less and I think it looks sweet. This is what it would look like....15x9/10 and 17x4.5 in the front...

sell me your rears once the 15s come in lol

weld just designates 15's with a beadlock as .33 more, not every 9" wheel is gonna fit

Haven’t ordered them. Was waiting on some input.

Was really hoping the 15x9 would work with out a prob. Just don’t want to sell my rears and end up in a position where the 15x9s don’t fit even with some grinding. This looks to be the problem child...

[MENTION=10868]AdrianMAK[/MENTION] any guesses?

Not 100% sure man. I would need to make a few phone calls.

To achieve fitment with 15's - you have to run the rims pushed out a bit to clear.

In doing so, this places the tires right in the destruction path for the fenders.

The fix is running a little more negative camber.

This is what I have NOTED in my PDF for alignment and shock settings for our customers:

 You may not be able to run ZERO CAMBER without using a BMR extended length Camber Link (UTCA064) OR if you are lowered excessively

 If using 15” rear wheels with current conversion offerings, you will likely need to run around -1 degree of camber for tire clearance on launch. This is why I suggest using a 17” wheel currently.

Thanks for everyone’s input. I went with 17x10s with 305-45 MTs. Will calm my OCD about having 18s in the rear and 17s in the front.
