Ok Im sure this has been asked dozens of times by now, however on the search function, amongst the PK Auto spam, I don't see anything relating to this, so I'm going to ask it (possibly again). We have a 1320 and a Scat Pack, and both of them just spin like crazy on a race track, and roads in general, even with soft compound tires. Yes I know the 1320 is set up for drag, but this family prefers a track with turns. We wanna do 315 soft compound radials on the rear. Right now, we're looking at MRR M392 11 inch rears and 9.5 fronts. The 11 inch wide rears have 24mm offsets and 6.9 inch back spacing. We are hearing several things from different people. Some say they fit fine. Some say the rear fender well needs to be cut on the inside rear edge. Some say it needs 3mm spacers. Some say it needs 25 or 30mm spacers. With wheels like this on stock suspension, do you really need spacers? I feel like they would clear the brakes just fine. Im not sure about the wheel well though. Anyone have experience with MRR M392 11'' on a scat pack or 1320? What did you do to get them to fit, if anything?
