Any FIA guys running 10" rear wheels?

[Russ Dickey]

I'm still doing some research on my pending wheel change. Any of you FIA guys running a 10" wheel on the back, and if so, does it fit without any clearance problems?

Russ,

If you're referring to tire section width, I run 275/60/15 Hoosier Street TDs on the rear for track use, and they have an 11" section width. No problems at all. If you really mean a 10" wheel - - -

I did a double take too... but I'm sure Russ is referring to tire width.

[Russ Dickey]

Sorry guys. Yes, I was speaking about the actual wheel width being 10", not the tires. I am looking pretty hard at those bolt-on FIA wheels from the other thread, and while Alan told me that the backspacing would work, he said that they have never run a 10" wide wheel on the back of an FIA.

What I am basically wanting to make sure of is that once I have tires mounted on these wheels, that A)the tires won't stick out from the fenderwells, and B)that there won't be any tire rub when going over bumpy roads or under hard cornering.

I realize that much of that actually has to do with tire size vs. wheel size, but at the same time, the FIA fender well is only so wide, and the larger wheel will allow the tire to expand more, thus possibly causing me clearance issues. When I switched from an 8" wide rear wheel to a 10" wide rear wheel on my '66 Mustang, I had clearance problems even though I was running the exact same 255/60 tire on each.

Silk, what size rear wheels are you running those 275's on?

Maybe I should have worded my question differently: Are any FIA guys running a 10" wide rear wheel, and if so what tire size are you running and are there clearance issues?

My wheel in the rear is a 17X10.5, with a 315/35/17 tire. I do not have any problems with rubbing, and the wheel tucks in the fender well quite nicely.

Justin's rear end was narrowed 3" to except the wheels he bought so you can't go by that.

I didn't know that. I thought they just automagically fit.

There was another guy at homecoming in 05' with a silver and black fia that had 315s on 11" Compomotive bolt on wheels. Maybe Alan can get you his phone number and you can see what back spcaing those were.

Silk, what size rear wheels are you running those 275's on?

9 1/2 x 15 Trigos.

Russ,
There is a picture on Club Cobra of a 427 Unique running those Compomotive FIA wheels. I looked at them at one time before we went the Trigo route... Anyway the CC picture looked like rear end accepted them just fine. Not sure the difference on the Unique 427 body width and rear end width however...
