I'm trying to find out the stock rear spring rate for a 90 Mustang GT.
I'm slowly but surely getting my suspension together on the car and started out using Kenny Brown parts. I'm at a point now where the KB parts will no longer work due to fit problems with the exhaust system. The KB pan hard bar will only work with a select type of catback systems and once you buy it you will be stuck with that from now on. Their front K member kit will not work at all with long tube headers which is what I have.
I've decided to go with Max. Motorsports pan hard bar and UPR's front coil over and K member kit. I will be going with KB's basic formula on the starting setup. This is basically stock sway bars, stock rear springs and
650 lb front springs when using a pan hard bar and coil over/K member kit.So far suspension/chassis changes are Tokico 5 way adj. shocks and struts, M&M camber/caster plates, KB upper & lower adj control arms, as well as KB strut tower brace and extreme sub frame connectors. I also have UPR's torque box braces installed. Any input from the suspension guru's out there would be greatly appreciated.
