Indeed. The spoilers on Enzo, 430 Scuderia, Clio V6, Autozam (why this but not 458), Fiat 500 and so on look nice and fit the cars really fine. No way I'd be ruining my cars with the normal spoilers (except for the 458).
It would also be nice to use the stock spoilers on cars to adjust downforce, like the one on the old Renault Megane coupé 2.0.
