[QUOTE="86merc, post: 11527112, member: 82554"] For coil overs I usually use Afco springs. I get a deal on them. But you can get them from Summit and other retailers pretty easily. Hypercoil springs are a good choice as well. The rear springs I run normal coil springs. I have tried the bolt on style coil overs in the rear on a couple of cars. They had clearance issues with axle rotation and caused bind. Unless you do a correct coil over conversion I recommend staying with the stock style springs. You can get rear springs cheap through Advance Auto Parts, NAPA, CarQuest and so on. Usually $50 or so on the rear OE replacements. Plus you can usually source used ones from buddies for free. haha Because they are cheap I have several I have tested with. Because I set the suspension up with anti-squat the spring rate does not seem to effect much. The control arm lifts the car more than the spring. So I pick a spring that gives me the ride height I need to get the control arm chassis and rear end mounting points where I need them. Especially in a application where I do not have any additional mounting points like on a stock car & housing. If the car is too low it is a big issue as the chassis mounting points are below the rear end mounting points. Which is bad. It seems companies have finally figured out about anti-squat brackets (I have been making them for years as have some other crafty people) and now are selling them. But not all classes allow that modification. So ride height is about the only way to move the mounting points around. It seems 1990-93 LX with a/c springs are usually what works best. I usually use either rubber or poly spring cups to fine tune the height a little. I never cut rear springs. If you can find a Rockwell spring chart online you can see all the different year and model specs they offer. Specs like spring rate, free height, installed height, spring wire diameter and so on. You will even see some different ones like the McLaren and Saleen cars. The Capri even uses a different spring and rate than the same year Mustang.
