First of all, airdams are mostly uneffective. That's why NASCAR has splitters on their new cars. Unfortunately the best racing splitters are the worst street parts. If you can add a splitter that is removable, then you can have a good track part. But that means it has to bolt to the bumper itself, not the plastic cover.

But that's not what the S2K needs. The S2K has oversteer, so you need to plant the back end. A nice fat rear wing like on the S2K CR is what you really need. Then again you might as well buy the whole CR body kit.

Except that the S2K has snap oversteer. A wing will help constant oversteer, but it won't do much for snap oversteer. That's where suspension tuning comes into play, and that's what you need. A good set of tires and shocks will get you more handling than any aero. Aero does not work until you hit 60 mph and even then, the effect is small. Chassis tuning will get you further.
