Ok, here is my situation..... A few days ago the passenger side ball joint on my 94GT started singing a very squeaky tune. Sprayed it with WD40 and it immediately got nice and quiet. I have since priced out Ball Joint replacement vs. stock replacement arms. In both cases, the parts and labor involved put me right near a pair of MM Tubular Control Arms- http://www.maximummotorsports.com/Non-offset-Front-Control-Arms-1994-04-Mustang-P393.aspx Since I already have their CC Plates and a brand new set of SA Koni Yellows waiting to go in, I am only a coil over kit away from being being done with the whole front end for the most part. The car has, as far as I know, either Motorsport B or C springs in it. What is a good Coil Over Spring Rate for a street driven car that runs on crappy Southern New England roads? Should I stay right around 300lbs.? I have every intention of calling MM tomorrow to get their advice. I am just curious what you folks may have experience with. Once the front end is done, I am going to take care of the rear lower control arms and shocks. At that point(few weeks out) I will probably get a matching pair of rear springs if MM recommends it. What say you all??? Thanks.
