Is anyone running GT-R wheels on a coupe? I need to go to a bigger wheel width than stock as I need more rubber on the ground. The problem with GT-R wheels is that the offset is 25 and our stock offset is 45. I don't want to get into grinding the wheels at a machine shop as I don't want to compromise the integrity of the wheel. Will I have rubbing with only +25 offset?

 

I've seen a few coupes with them...don't think you'd have an issue but might have to play with the camber a bit depending on what tires you wanted to run.

 

Should clear w/a 275/30 in back, might have to trim the rear fender bracket depending on your drop & camber.

 

Ran them for a few months. I was running 255/35 in the rear and 225/35 up front. I would definitely suggest a little more meat for the tires. Careful with the rear though because they poke a bit, so as mentioned, a little camber is needed to clear the arches. The front wheels will probably need a 10mm spacer to look good. They were too sunken in for my tastes.

FRONT PROFILE (without spacer):

 

Thanks guys... I am presently running 255 on the rear and would like to go to at least 285, even 3015 of they will fit. The lower positive offset will bring the wheel out more increasing the chance of rubbing on the wheel wells, so you are right some additional negative camber may be required. I'm not crazy about doing this as I was wearing out the outer edge of the tire with lots left on the inside
Nice to see the pics... thanks! I think the meaner look of the GT-R wheels is perfect for the look I want.

 

This is coming from a person with rear wheels on his coupe the same size as the GT-R wheels. You will not fit a 305 - there is just no way without an absurb amount of camber and fender modification. A 285... maybe. I am running 255/35 tires and they rub the fender liner already at that size. To go any wider with this size wheel you will likely need to gut the fender liner and bumper bracket.

 

Ryne... thanks, I was afraid of this. When you say that you are running wheels the same size as GT-R wheels I am assuming that they are not the OEM wheel. I know of other wheels that will work with 305's, I was just wondering if the GT-R ones would work. There was a member who posted in the forced induction forum that this combination worked. Thanks to RadioFlyer for this information:
Rays Gramlights 57Xtreme
Rear: 19x10.5 +43 305/30/19
Front: 19x9.5 +35 265/30/19
and he has no rubbing.

Correct, they are not OEM wheels, but they are the exact same size - 20x10.5 +25. The example you posted above has an offset which is 18mm more conservative than my wheels and the GT-R wheels. This means the wheels are further in the wheel well by approximately 3/4", leaving room for the extra tire.

Since tires move in both directions when increasing size, going from a 255 to a 305 tire requires 25mm of additional clearance in both directions. His more conservative wheel size is the reason he can fit this wider tire.

 

Agreed... my main goal is rubber on the ground. I am presently on 255 Pilot SS's and they are a good tire, but not enough footprint to hook up with forced induction. It is a little scary when the slip light comes on at 4K RPM. Appreciate you sharing your experience with GT-R size wheels. I don't have a burning need to go to 20's. I just need better traction and would like a more aggressive looking wheel.

 

If traction is your main concern, get a 10.5" wheel with an offset in the 40's and go with 285-305 tread. It won't be GT-R wheels, but there are tons of great options out there. The diameter of the wheel is really irrelevant.

 

This x100^^^
And a lightweight set even better. There's many great 18" wheels that you can run plenty of tire, won't cost as much, are lighter weight and still look nice.
