Question about: Summit 15X8 Star wheels
I just ordered my Summit Star wheels for the rear.
http://store.summitracing.com/egnsea...3&autoview=sku They are back ordered so I have time to change them. I am now wondering if I ordered the correct backspace. You can get a 5.50 or a 4.50 backspace. I can not find the thread where I was told which backspace to order in combination with a 3/8s spacer to fit over stock rear brakes. I ordered: SUM-521-5866PS Rim Diameter (in): 15 in. Rim Width (in): 8.00 in. Backspacing (in): 5.500 in. Offset (mm): +25.00mm Should I have ordered the 4.5 backspace? I did some searching and it looks like the 5.50 backspace is what I need but still would like some feedback to confirm.

Re: Question about: Summit 15X8 Star wheels
Either one will work, but the conventional wisdom is to get the 5.5".
It puts the wheel a little further into the wheelwell, but has less of a dish. Steve |

Re: Question about: Summit 15X8 Star wheels
Which one with a 3/8ths spacer would not require grinding of the calipers or would both be ok?

Re: Question about: Summit 15X8 Star wheels
My 275/50/15 MT DRs are here and the Summit Star wheels will be here Wednesday. I plan on doing a test fit this weekend and will post pictures.

Re: Question about: Summit 15X8 Star wheels
The 5.5 will hit the banjo bolt on the brake caliper if you`re using stock mach rear brakes. The 4.5`s will fit with a 1/4 spacer. I switched to gt rears and 5.5 bs the fit is much better than the 4.5`s. With the stock rear brakes and a 15x8 4.5bs and a 1/4 spacer the MT 26X10.5`s were almost even will the wheel well.

Re: Question about: Summit 15X8 Star wheels
You will still have to grind a little off the sides of the calipers and a little off of the banjo.

Re: Question about: Summit 15X8 Star wheels
Wheels came today. Test fit with 3/8s spacer shows I will need to grind on the banjo a little bit. Plan of doing that this weekend.

Re: Question about: Summit 15X8 Star wheels
Did a little grinding on the banjo tonight and mounted the wheels and tires. Perfect fit with a 3/8th spacer. Pictures will be posted this weekend.
