I corded both of my front tires at the last event, and since they were the second set of fronts I've used on the same rears, I thought I'd upgrade to 17x11's on the front as well. I have a couple of questions about it. I'm looking at the AFS 17x11's (I have them on the rear), and Khumo V700's in 315/35. I can't afford the Hoosiers right now.

What backspacing do I want?
Where do they rub?
How much turning radius do you lose? Will I still be able to drive to the events on them?

Thanks.

I belive the combo is 17x11, 50mm offset with a 1/4" spacer. I have seen a couple of guys try this... but all of them rubbed.

Wow, what a steal of a deal!

I have the info somewhere at home, I thought that longer wheel studs were used also, hmm.

 

I am running 17x11's all around. 50mm offset. You will need a 1/4" spacer. With my wheels I had to grind away the "bump" on the spindle. You WILL need longer studs. Dont skip them.
In the rear I am not using a spacer. I have rubbing issues with the lower control arms. I cant use a spacer or I will have rubbing on the fender lip.
I am going to Hoosiers next year and will need to use a spacer in the rear. I will have to pull the rear fenders out (flare) slightly. This isnt really required on a car that is lowered a normal amount and/or not autocrossed.
The cars vary so much there really isnt a perfect wheel offset. However if I could do it over I would get 17x12 CCW wheels with 335 Hoosiers and flare the fenders.

 

DONT DO IT! They look horribly ugly in front. JMO

Cool, thanks everyone.

I have a set of the 50mm offset 17x11's/315's in the rear now with no rubbing issues, but I noticed that AFS keeps selling blemished 17x11, 36.5mm offset rims on E-bay cheaply (I've seen $330 for a pair a few times). I already have the longer ARP studs in the rear, could I run these out back with a spacer? I would move the current 50mm ones to the front.

If that won't work, I'll find some 50mm offset rims. I also noticed that Khumo's specs on the 335/35/17 Ecsta V700 say it'll work on a 11" wide rim. Any reason I shouldn't put these on the rear? The car is setup to be pretty neutral with the 275F/315R setup, I'd have to soften up the rear/stiffen the front to compensate for the 315's all around.

I bought 4 of the 17x11 36.5mm offset wheels from AFS off ebay just last month for the prices you mentioned. Right now I'm running them on my '94 Formula with 275/40 V700 tires and I have no clearance issues. I'll upgrade to 315 tires over the winter most likely. Anyway, with the 36.5mm offset in the rear you will most likely have to slightly flare your rear fenders. The 36.5mm offset moves the wheel and tire out for a wider track width, so no spacer is needed. If you choose to run these in the front, you may need to cut the upper section of the black inner fender liner and hammer down a vertical metal lip buried underneath, but only if you're lowered close to 2" for what I've heard. No other mods needed.

yeah what he said. But since you already have 2 50mm wheels stick with those. You will need a slight spacer in front. You shouldnt be using one in the rear. Is that right?
I like the added track of the 36mm wheels. But I got 50mm to avoid body work. But the body work will come next winter when I go to 17x12 CCW wheels and 335 Hoosiers. Then I will just have some nice flares molded in on front and back.

 

Frig, 17x12" all around? I'd like to see that, and what the clearance is like in the front

 

I figure I would have them built with the same offset as the 36mm 17x11's only with the added width taken into consideration. They will definately stick out. But I will add flares to clean up the appearence. It will be UGLY or AWESOME. Whichever it is I will like the performance!
I think I just scored a 93 trans and the engine will be built this winter so I should be good to go next season. Excitement is building already.

 

So, will your flares look anything like this car? So far it's my model.

Even if some think its ugly because its different, it will be a friggin G machine. If it can be done without serious problems incurred or tubbing the rear that would rock, biggy wheels, yummy.

 

Okay, I'm starting to get my plan together. Thanks to everyone that responded. If there are any flaws in it or I am doing something stupid, let me know. Looks are not a factor, I'd run the Ronal Bear wheels in 17x11 if they made them and they were inexpensive.

Front - new 17x11, 36.5mm offset w/my current pair of 315/35 Victoracer's on them. The hubs get replaced every year (thanks PepBoy's lifetime warranty), and new studs are part of the package. It'd be a PITA to swap the long studs every hub change (and the short ones onto the cores), so if I can avoid a spacer in front I would like to.

Rear - current 17x11, 50mm offset with new Ecsta V700's in 335/35/17, assuming Tire Rack can confirm they are safe on a 11" wide rim as their website specs state, otherwise the 315/35 Victoracer's.

These would be race only, and only have to conform to SCCA SM rules, so is there any reason to run fender flares? I do about 12-15 events and one opentrack event each year.
