I can tell you my experiences...I just put a pair of 315's on this week...
Trying to put 315 MT DR's on my '94 caused all kinds of clearance issues. I have Steeda (adjustable) lower control arms and I can't remember who made the uppers I put on the car, but my 315's hit the quads (flipping them didn't help), so I had to remove them altogether. Then, the brake cable bracket (that's bolted to the lowers to keep the e-brake cable and the anti-lock sensor wire away from the wheel) is hitting the wheel, so I have to fix that tonight. I had no problems with the exhaust pipes on the driver's side (plenty of clearance), but the passenger side the pipe hits the tire. I've had numerous pipe 'upgrades', so it goes to reason that it's hitting now...I'm going to run the car over to a custom exhaust shop and have them fix up the exhaust on that side.
