I'd like some input on this as well. I hear there may be a problem with an IRS bolt and clearance. Anyone have any experience with this? I'm planning on 275/40/17 in front and 315/35/17 in the rear, BFG-kd's. I'm assuming I'll need a 1" spacer to clear the IRS bolt. Anybody out there have a similar setup?
Hey guys, you don't need a flathead bolt or anything like that to clear the IRS mounting bolt. All you have to do is get lowering springs. When the car is up on jacks or at stock height, the bolt will make contact with the tire, but when it is lowered, the bolt sits inside the wheel well & makes no contact to the tire. Here's a picture of my car with the fattest 315's (GoodYear GS-D3)that you can buy on 17x11 wheels.
