widest rim?

Let me tell you from personal experience that a set of 315s on the back of any muscle car looks incredible

thanks and im sure that you had a nice chat with people who developed the car.

345s ftw...

I felt around in the fenderwell, there's a pretty good gap between the tire and inner panel. I didn't check gap between strut and wheel/tire, that may be the limiting factor. The silver car had 275/40 ZR 20's on back

mmmmmmm....

315 on my ttg35

25mm spacer, perfect fit

If someone comes up with the correct offset wheel, I don't see why a 305 won't fit .. I mean the 275s on my 04 cobra were pretty tight, but with the correct offset wheel, I was able to do a 10 inch rim and 305's with no other modifications.

That is one thing I don't like about this car .. why would they lock you in to a max width wheel STOCK .. they should allow for more aftermarket or GMPP wheels with larger widths for those who want them ..

My guess is that aftermarket companies will find a way to do this without "tubbing the well or serious modifications" .. if not ... it will be a damn shame as it is always nice to have more tire out back when you start getting more HP up front

Note even that much

275 mm
10.8267 inches

305 mm
12.007 inches

That's the plan!! Either spacers, a higher offset, or a combination of both. I'm pretty sure the IRS leaves no room on the inside, but with those wide 1/4's GM left us plenty of room on the outside face. The problem I forsee is that I wanted a drop also.

Cutting up the original wheels wouldn't really work would it? The spoke design dictates that any width you add to the rim would push the inside edge closer to the inner fender instead of adding a lip to the outside edge. I suppose you could combine it with a spacer but then you increase the risk of lug bolt failure.

Well if you added 2" inches (11" new wheel) to the width it would give you less room in the back, but if you add a 2" spacer I'd think that would even it out. I'm no expert on wheels by any means, but that just seems to make sense. The only problem you may have left is clearance on the ouside, but looking at pix of the pre-po's it seems like there's room to play with. I've already started researching some companies that widen wheels around me; I can't find any wheels that look better than the stock wheels and are wide enough to accomdate the tires I want so this looks like a good plan for me... widen em, powder coat em black and throw some spacers on! You can easily fit 315's on an 11 inch wheel.

I was also thinking what if you were to widen the 8" front wheels to place on the rear by 2.5 - 3", then put the stock rears on the front with a 1" spacer... that way you can have wider meats all aorund and it'll be way cheaper than widening on 4 wheels.

Headpunter - Can't you just hit someone up for the current Front and Rear Offsets for the 20's and 21's ? We can do the calcs from there on what the offset increase would need to be or the combo of offset and spacer would have to be.

Thanks

[Hesh]

thanks on finding that out headpunter you are truly a wealth of information.

[2010_5thgen]

id like to get atleast a 295/22 rear and a 275/21 front if possible. if not ill just do a 285/22 rear and the 265/21 front.
