I want to buy these wheels.I have stock rolled fender. Will be any fitting problem because of brakes or arms?

Or need i same wheels with 8'' backspacing? http://www.championbillet.com/polish...ck-rear-wheel/ Or this one with 15x10 - 8'' Backspacing

Please help me.

 

Is this for a drag set up? If so may I suggest you run the thread by the FI forum as they will have the most experience in this field.

 

Yes it is for drag and road setup. Thank u. I will run the thread to FI forum.

 

10" with 8.5" backspacing works out to an offset of +76mm. I am guessing that would rub on the inside suspension and possibly not clear the brakes. 8" backspacing would be better, and even 7.5" should be fine (at least for outer clearance) with rolled fenders.

 

I agree, if 8.5"? = 76mm. Then that isnt aggressive enough to avoid inner clearance complications. 8" would be the better option.

With a 10" wide rim, no more than +72mm is where you want to be. Depending on the tire you want to run, you should factor this in for fitment, its overall diameter and width on said rim. I assume since it’s for drag, that it will be a slightly pinched fitment to gain the most squat/strait line traction. Rolling the fender is always a good idea, you can gain an extra 20mm of outer clearance to play with doing this, so naturally you can move your offset out in the +55-60 range to add to the inner headroom. Keep in mind, less rear camber offers the best strait line traction, but will decrease outer fender clearance, wile increasing inner clearance. So depending on how much tire you squeeze on that rim, you want to make sure its centered in the wheel well with alignment and ride height factored in.

 

Why do you want a 10" wide wheel?

 

Now I'm using 17'' +48mm wheel.

If I buy 15x10 +76mm, inner clearance will be 47 mm less and outer position will retract by 9 mm.

If I buy 15x10 +64mm, inner clearance will be 35 mm less and outer position will extend an extra 3 mm.

If I compare my wheel with for example volk racing ce28n 17x9 +64 mm version
inner clearance will be 22 mm less and outer position will retract by 10 mm.

A lot of people using these wheels. As a result outer position is not a problem for stock fender and also clear the brakes.

Also i know lots of people using 17x10 +72 mm 949 racing 6ULR.
With this wheel, inner clearance will be 43 mm less and outer position will retract by 5 mm compare to my wheel

I know that with 43mm less inner clearance, wheel do not rub inside suspension am I right?

I think problem is 4 mm less inner clearance and also 2'' smaller wheel.

I think 8'' backspacing will be perfectly fit. But I need 8.5'' backspacing model.

Nobody tried?

 

10'' wide rim and +72mm is a limit for s2000?

 

For inner clearance, yes. Some guys have run up to a 10.5 +72 but had some inner rubbing under suspension movement, so because of that there is no reason to recommend the set up if it has complications/limitations on ride height/camber and suspension compression. So, if you’re going to run a 10" run within a +50-70. The higher offset you don’t need to roll the fenders, +50-65 range you do for a 10”.
