My ride height is stock now but I would like to put some H&R Race springs on it. Will it rub with that set up. The Tires are MT drag radials 315/30/18 on 10.5" FR500 wheels. Thaks for the advise. If you have any pics of similar set ups, please post.
Lowering it shouldn't cause it to rub anymore than it would otherwise I wouldn't think. Maybe it would rub the fenders easier but IDK. The first place for it to rub would be the forward IRS subframe bolt when you have the car up in the air and the load off the suspension with the wheels hanging. If they're not already rubbing you should be fine.
I'm running 315/30/18 PZERO's on 18x10.5 replica's with MM button head subframe bolts, and 3/8's spacers,(for cosmetic reasons and not clearance purposes) and unrolled fenders, and have no rubbing issues.
Factory replica's and FR500 replica's have different offsets and backspacings as FR500's are DD wheels so I'm not sure they put the tires in the exact same spots or not.
