I'm after a second set of track-only rims for my TJ sports. I've been offered a set of RX7 Series6 rims for $200, which look like they may suit. Specs are:

16x8", 5x114.3 PCD +50 offset. I already have a set of 225/50/16 Yoko Advan 32R semi-slicks to go on them. According to my calculations, these should fit pretty well. 4mm more offset, but the rims are 1" wider that stock. So it should sit roughly 8mm further out than a stock rim, according to my calculations.

Does this sound right? My other concern is they might foul suspension arms, having a higher offset than stock, and being wider too. But 225mm rubber isn't exactly huge, methinks it should still clear the arms?

Try looking at some AU, BA, BF Falcon wheels. Same offset and stud pattern as Magna and they are cheap and plentifull.

:doubt: Don't think they'll fit. Save this link for future reference.

Don't worry about tyre, rim won't fit.
