Hi Everyone looking for purchase a set of Gramslight 57D for my GTT. I had read a bit of the old post here, some say they can run +20 to 22 all round without any problem, But most people do +35 to +30 offset. I have no idea which will be the best offset for the GTT. Current with HKS hyper Max 2 coilover with 1 and half finger gap all round and RPF1 18 x 8 F, 18 x 9 R and +35 offset. I think that combination is quite nice for GTT. The problem is the 57D ONLY come with +38 or +22 offset Is thinking of 18 x 9.5 +38 F and 18 x 9.5 +22 R, or +38 all round? Planning for using 245 40 F and 265 35 R tyres. I am after something without guards roll, no stretch tyres and no massive camber. Please help Thank you.
