I couldn't imagine throwing down the coin on a Saleen suspension compared to what I could get from Maximum Motorsports. MM is much better, priced better, and the customer support is excellent.
If you can get the opportunity, drive a Saleen with the full Saleen suspension and then drive/ride in a MM prepped car. MM has a two or three actual level of suspension setups which vary a lot (depending on if you have a daily driver, want a really lowered look, or if you want a streetable, yet road course worthy setup). MM has matched parts so you can build as you go, but can be assured that all they parts work together for a specific purpose.
I have the Road & Track Kit from MM, but haven't purchased the panhard bar yet. Absolutely incredible and I didn't spend anywhere near what Saleen costs and I'm pretty sure I've got more upgraded parts in the process.
Not knocking Saleens for sure..........just wouldn't go that route on a non-Saleen Mustang. Not sure what I'd do if my car was a Saleen, but now that I've experienced MM, I'm spoiled.
I agree MM is the way to go. Or if you really wanna spend that kinda money go with Griggs. They have a great coil-over double wishbone front suspension for our cars. Thats right you heard what I said.
