After 3 days of reading and, researching, as well as talking with chris and a couple other guys, I wanna see what you guys all think. I think these will fit but thats where I need your guy' help. I know I will need to roll the fenders quite a bit but is there anything else? I plan to do these rims http://www.summitracing.com/parts/are-427p7956547/overview/ Which are a 17x9.5 with a 4.75 backspace, all the way around the car. The front tires will be 245/40/17 while the rears will be 265/40/17. Nice and snug and im hoping they will fit, my car is fully stock with the addition of disks on the front.
They do make these in an 8in, but why wouldnt it work? There's a guy who runs 10in wide in the front, and chris runs 9 in the front as well with a 265 tire?w
I didn't know Chris was running 9s in the front, cool, go for it. I would love to see those wheels on a mav/com.
I am curious as to how much offset if any I have to run, how much room is there on the inside, from the mounting plate in. And also from the mounting plate till the edge of the fender? Would a 4.75inch backspace on a 9.5 inch rim work? I would go out and measure but I'm at work =[ I mainly just want to make sure these wheels with this backspace will not be on the leaf springs..
They will work on the back. I've got 10's with a 5" backspace on mine with 295/50's (15's) The front's a whole nother ball game with the wheel movement. All I can say is try it, but don't be surprised when you get wheetl and/or tire contact.
Just make sure you remember the widest part of the tire changes as the sidewall height changes. A 295/50 has a width of 295mm-11.6" but because its sidewall height is almost 6" the widest part of the tire is at a radius of 10.5" out from the center on a 15" wheel. The actual contact patch (width of the tire at the outside edge of its diameter of 26.6) may only be 8" This makes a huge difference in how a tire fits as the top edge of the tire is the part you are concerned with hitting your fender. That same 295 with a 35 aspect ratio would not fit without using airshocks or body work because the widest part of the tire is out towards the edge. I know this because I have 600.00 worth in my garage with the inner edge melted where it rubbed against the inner wheel housing. Something else to consider when choosing a wheel and backspacing is the amnt of room to the upper ball joint. I wanted to run a 10" wheel up front but adding 2" more backspacing to my exisint 17X8 wheels would have put me at 6-6.5" of backspacing. This runs right into the upper ball joint. Would an 18 work??? IDK. I now have drop spindles so problem averted. Its one of those things you just have to try. Mustang wheels with large offsets can be found cheap. Get a set of 17 or 18X10 and play with them with stacks of washers to find what backspacing you can get away with and then look to see if it fits inside the wheel well if not then maybe a 9" with that backspacing will. Keep subtracting width but keeping the same backspacing until it works. Mayke sure you check for space at full bump and lock in both direction. I am no longer running outer shock tower frames and bumpstops because the tires wont fit with them in there.
The bad thing is they(summit) say once ordered there is no return so you better make sure what size you want because they are special order.
