Coilovers all depend on your budget, you get what you pay for. If you're cheap, you get cheap crap. Spend the dough and get the good stuff.
Rack spacers will reduce bump steer, which will increase the lower you drop the car.
Rotated transmission mounts crank the engine forward a bit so that the axles are lined up correctly as to avoid breaking your CV joints as often.
Also after you lower your car get an alignment done. I've been lazy and haven't gotten one yet.
hmmmm maybe thats my problem... do they have a set for the 2.2 automatic trans?
