Anyways, 15" wheels do not fit over the stock Cobra brakes in most cases, or the IRS, so grinding has to be done. People have been grinding the IRS knuckle and tie-rod for years, and on the brakes a little. These new wheels clear the OEM Cobra rear brakes with no issues. However the IRS still gets in the way. So a simple fix with the angle grinder on the IRS knuckle and very bottom edge of the tie rod took care of that. The way the bolt goes through there's still a decent amount of material closer to the bottom. The bolt goes through like seen in this picture:
The wheel:
WELD RACING RTS 15x8.275 with 5.50" backspace
But basically when you try to put the wheel on, you'll see where it hits..so you just grind a little at a time, put it on, check, remove, and repeat until it clears. Once I got mine down to where I just had to remove tiny thousanths of an inch at a time, I painted it, put the wheel on, spun it, removed it, and ground it wherever the paint was nicked.
Here you can see where it was rubbing without material being removed from the IRS knuckle where the tie rod bolts in.
And this is pretty much what you end up with when you're done grinding.
I also took this time to re coat the wheel wells, and re paint the brake calipers (no pictures of those redone, sorry)
And this is the clearance you end up with once ground down:
And the clearance on the inside of the wheel well with the 28x9 slick:
And installed. They tuck under pretty well..probably could've went with a 4.5" backspace for less grinding.
