[quote=“gt1cooper”]Also, didn’t the bigger cars run on 255 r15s?
You might also want to say only standard transmissions.[/quote]
I had seen widths cited between 6"-8" I went with the 8’s because we’ll need the grip without an LSD. 255mm sounds more like le mans than trans am but if you found a source for them however I’d love to check it out.
I’m not sure what you mean by standard, I am going to change it to single clutch.
