cant go wrong with equips and if need insperation well here you go..
like stated before, good set of rims. the selection you have are really good choices
good exhaust maybe coming out a little bit, (buddy club spec II?)
better wheel fitment AKA slam and roll the fenders
and if you can greddy intake manifold? will clean up your engine bay up a lot
but honestly you have a really nice car and you are really close from having a very very baller car
if you wanted priorities here is what i think
1. new wheels/wheel fitment/dropped ext.. also lights (details go a long way)
2. crack dash/gauges/steering wheel
3. exhaust
