I have some seat time, I was previously running some 17x9.5 forgestars and 28x10 bias ply slicks but that was a stock long block and stock GTR turbo setup on E98 so around 600whp. Previous best was 1.68 60ft, I have some suspension work to do as well but I think I can get 2/10ths off that.
I'm waiting on some fittings to get this installed, seen it works wonders for launch consistency and reducing shock load on a few high powered Evo's here.
