I would appreciate your help, will the GT350R tires fit on the GT350 wheels and on the car? Reason, I would like to get a set of Michelin Sport Cup 2 tires for the track for my GT350 and the Cups aren't made in the stock size, only the Super Sport. The GT350 comes with 295/35ZR19 F and 305/35ZR19 rear, the R model with 305/30ZR19 F and 315/30ZR19 rear. I would like to pick up a set of OEM wheels and have a set of Cup 2 tires mounted on them and be able to switch tires for different track conditions. I am not racing but really enjoy open track sessions and need a spare set of tires anyway. My car is driven 95% on track only. Only occasional road driving. Thanks.

Excellent question. If I were you, I would talk to the Michelin Rep at Tire Rack. I have found them very helpful in the past. The other thing you may wish to think about is that the OEM GT350 aluminum wheels weight 31lbs a piece! That is way heavier than they could have been. Which makes me wonder than other than cost reasons, why this was done. I suspect it was to also exacerbate the differences and advantages gained by the lightweight R carbon fiber wheels. Think about this - each "wheel pound" represents a pound of rotating unsprung mass which is roughly equal to 4.4 pounds of unsprung weight. Coming from a series of Z06 and ZR1 Corvettes, I really notice the front end weight of this car. Monoblock forged wheels are available (at a price!) that would shave about 9 pounds off of each stock aluminum wheel - and that is a lot. What I don't know, is if doing this will at all negatively effect stock GT350 suspension settings - if they are that sensitive to this type of change. I am trying to find an answer to that...

One answer to that is DSC Sport V3 suspension controller. Programmable via usb from laptop and via wi-fi. Can make adjustments for changes made re: wheels and tires. About $1495.

Did you ever get any clarity on this? I’m trying to get a set of CF wheels for track use as well on my GT350.
