Any recommendations for offset to fit?
Thanks.

No problems at all...plenty of room up front. I'm using TRMotorsport wheels (the fronts are NLA now from TireRack) in stock widths, of course, 8.5" and 9.5". The wheels are manufactured with a 44mm offset on the 8.5 and 35mm offset on the 9.5. I'm using 18mm spacers all around. This gives a net offset up front of 26mm, so that is 3mm further outward than stock. In the rear it gives 17mm which is 6mm further out than stock (note the SCCA max offset change rule is 0.25" or 6.35mm).
I have a set of 12.5mm spacers for the rear in case I needed them, but the 275 Rivals have shown no rubbing using the 18mm.
Up front as long as you stay at stock (29mm) or less (I'm at 26mm), I don't think you'll have any problems up to the rule limit (23mm). In the rear, there is plenty of room, so anything from the stock offset, 23mm, out to 17mm should work fine. I had pondered trying the 295/35 Rival in the rear (and would use my 12.5mm spacer if I did to give a net offset of 22.5mm, essentially stock), and it should fit; however,
after my recent experience at the Performance Center autox, I'm happy with the hookup in the rear, so I'm sticking with the square setup for now.

Chuck
