SACHS Coilovers [$2k normally, but quite a bit more affordable when you work for them
]
17x9 RPF1s w/ good rubber for track days [another $2k]
Project MU Club Racer pads for track days [$400]
Berk single exit track pipe [$135, or around $80 used]
and spend the rest on track time.
(This is pretty much my plan anyways lol)
