There were 2 S4's at the track last Wednesday, and all I can say is DO NOT attempt to race one. Both of them ran high 13's. I do not think they had too many mods, because they looked stock as hell. The engine compartment is twice as crammed as ours (believe it or not!). The icing on the cake was that one of them had a childs seat in the front!! Well, any was, unless you are 3.0 or S/C, they will smoke you, HARD!! And they look bad ass as hell! I immediatley began to drool!!
