You can do alot with 2 grand.

Throw in a set of cams and some other goodies.

Or you could go suspension. With that kind of money you could have a Full Tein Setup.

Spend like $900 on SS Coilover Set
Another $350 if you want the EDFC for it
Skunk2 Upper Control Arms for Camber $250
Camber Kit for the Rear you could just washer out. Or even spend the money on the real deal.

Without the EDFC you'd still have $ to spare. Of course you don't have to go full Tein either.

$2000 isnt a bad lot to play with.
