Don't think they would fix, you would have to remove the quad shock, roll the fenders and probably bend your catback alittle so it wouldnt touch.
If you get aftermarket rear control arms you can ditch the quads without much of a change but since your setup seems to be for drag anyways they dont serve you much good at the moment anyhow
They are basically there to prevent wheel hop. So you wont really loose a lot of handling performance, but not sure if the tires would fit even if you did this.
they would not fit without serious modification. I have 315/35/17's and I had to modify the parking brake bracket flip the quad shocks, and massage the inner fender. you would have to tub it and run dumps in order for those to fit
Well I already run dumps so that problem is out of the way and I run 315/35 R17 tires now and they fit without a problem. Didnt have to do any modifications
