If I put a set of lowering spings, (just springs no bushings, sway bars, etc.) are there any other modifications or parts I should put on to compensate for the 1.5 inch drop?
well technically, you dont need anything else other than those springs. but if you are into the whole suspension deal, you can buy shorter struts and shocks, caster camber plates, upper and lower control arms, subframe connectors, polyurethane bushing kit, roll cage......
I installed Eibach Sportline springs on my 94 GT which lowers the front 2" and rear 1.8". I did not use the rubber spring covers so I could get that extra drop.
The rear is 1" off/raised from the front so if you are going for the even look you may want to ask for something that helps with that I am not sure what its called. I am looking for springs for my rear that lower 2. 1/2 to correct my issue.
