On my car I am running 17x10's in the front 17x12's in the rear (widebody car). I would try to goto a 13" wide rim in the rear with a 4" backspacing.

Good plan on getting the fender roller. No one rents them in the Ann Arbor area, so I had to use a heat gun and a body hammer to "roll" my front fender lips. It turned out better than expected, with no paint cracking (well, no more than what happened when my tires were eaten by my fenders).
G'luck. Don't forget to post pictures when you finish.

hey guys thanks for all the positive comments. here are all the details on my suspension and wheels.
respeed race coilovers on the front, spring perch welded at 6" from top of the strut tube.
respeed camber plates
technotoytuning roll center adjusters to correct the front suspension.
375 spring rate on the front, 200 on the rear
respeed coils for the rear and i took the height adjusters out so its just the springs
15x8" diamond racing wheels with a 4.5" backspace (or for those who like the offset measurement its 0 offset)
i have 175/55r15 tires all around and no rubbing what so ever.
i rolled my fenders with a baseball bat and a heat gun and had no issues.
when i get some more pics i'll post them..
also i know there is going to be alot of hate on my stretched tires but i make sure that my tire pressure is constant and i do not race my car either.

also i will warn anyone that wants 15x8 with the same backspace and you don't like stretched tires, you may have issues with tire rub.
here is a picture of how my rear wheels fit...

Just a hint of crazy.
Thanks for the pictures and info, I'm looking into these exact wheels but with 235 or 245 series tires, looks like I'll need to flare to get them safely under, how do you like the 375 springs? I have 350 fronts on the way for my V8, now I'm scared that they may be too soft, but I was worried about too much stiffness causing skip in the canyons, as the roads can get choppy. Glad to see someone else using DR wheels! Sweet ride.

That is incorrect, backspacing remains constant with whatever the rim width is, offset does not. I am running 4.5" backspacing front and rear. If I was doing it again I would try a 4" backspacing in the rear and run a slightly larger rim, but in the front 4.5" is perfect.
On my car I am running 17x10's in the front 17x12's in the rear (widebody car). I would try to goto a 13" wide rim in the rear with a 4" backspacing.

I personally run 245/45/17 on the back of my GSL-SE with +40 offset wheels.
That means there is approximately 162 mm of tire inboard of the hub.
162mm is nearly 6.4".
From that experience, I wouldnt hesitate to try 6" backspacing in the rear...
If 4.5-5" rear wheel backspacing is the norm, what the hell am I overlooking?
Also, just for reference, I have 215/40/17s up front on a +38 wheel.
Thats about 145mm inboard of the hub, or 5.7" backspacing up front.
What gives? You guys dont like to fill up the wheelwells or what? or are my calculations just retarded?

May I ask why you would reduce backspacing if you were to buy wider wheels?

i looked into 5" on the front with a 15" wheel it comes too close the the spring in my case with the respeed coilovers. and i think 5" would be the absolute max on the rear from what i saw. i just ended up going with 4.5 all around on my gsl
