Just my humble 2 cents...but 2.5 is pretty extreme of a drop. So are 19s. 5th gens look perfect with 18s, any bigger would just look lopsided...

As for body kit, I'm all for Wings West W Type, pretty much the most conservative kit you'll find, all in urethane too. PUSHIT also has a sweet setup going...the Greddy front lip looks hella nice on 5th gens too. Look around, I think there's someone selling a used Greddy lip for cheap right now.

GOOD LUCK!
