I think someone on here was able to fit these rims under their car. I want to do the same. I can roll the fender lip, probably will crack the pain but I'm ok with that. It seems that 17x9.5 wheels are more abundant. I am looking for performance not just looks but the car will sit 1-2" lower. Rafe158 I think put the same wheels on his car with 255/40 in the front and 275/40 in the rear. I need to figure out the backspacing if anyone can help.
Yea I was reading that, I'm wondering if he did anything else though to make those wheels fit as nice as they fit. His car is gorgeous.
OK let's see if this makes sense in the front he has 17x10" wheels, +18mm offset which is a 5.7" backspace. He is using a 255/40/17 tire. That's a 25" tall and 10" wide tire. For the rear, it's a 17x10" +18mm with a 1.25" adapter. Which would be equivalent to a 4.5" offset. He is using a 275/40/17 tire. That's a 25.5" tall and 11" wide tire.
I love the way those wheels look on that car, it's just a question of how bad they will beat up the fenders & quarters...If you have to roll the lip down to nothing....
Tolerances that tight on a car you intend driving very fast may be something you want to think about. You don't want something to rub at high speed and well, you know. If you dam the front to achieve even a little downforce, you will have significant compression at speed. I would think you need a very tight suspension to keep those tires where they need to be, compression is an issue in the front and lateral movement in the rear around corners. I've seen the slightest rubbing on the sidewall of a tire cause it to explode at highway speeds, I can't imagine what it would do at 120mph.
I don't like big wheels, you can run big enough tires with 8". That being said I'm going with 9.5" lol But only because that's the smallest size they make 2000 Cobra R's in.
I don't know whats up with those calculators, I usually do the math in my head. I tried one of the calculators and its not making sense to me. http://www.autolounge.net/calculators/tirespacing.html My math can be wrong, since I'm only human. I'm thinking it had to do with the decimal places. I used 4 and I'm not sure if the online calculators only round up to a tenth or something.
alright figured it out . . . I think, wheels are on order for about $300 per wheel, it's a lot but they are super light. I wanted something lighter but they just don't make that offset I'm looking for. Front will be 17x8 4.5" BS Rear will be 17x9.5 5" BS in the rear I didn't want to have that much of a size different from the front to the rear but I'm hoping it won't make the handling too bad. The rims are Center Line Split Spoke Competition Series
they really did a nice job with that design. I think they weight around 25lbs, that's not bad. It's nothing like the enkei or kisei which weigh 15lbs but still really good.
