kind of an OT question but maybe not: could I run a F.A.S.T. or stock class race with a set of G70-14's or would I need to say with the F70-14's?



Yes you can , they allow up to a MAX size of a G70 if the car had 70 series tires and a G60 if the car had a 60 series tire .

I have firestone redlines on the Dart , no issues here and the road around here are bad .
