sugestions on what front suspension to use

The alter-k is by far the best one. If you get the cheaper brake setup from them it's ford Granada or something like that. Longevity and parts avalibilty is no problem it's all over the counter stuff at your local parts store. Being they are mustang spindles you have a huge selection of brake options. I'm running wilwoods with my alter-k three years now and quit a few miles with no issues. I drive the hell out of the car.

Your best bet is to give bill at rms a call. He will explain anything you want to know to ya. Hell he may even have tips on how to solve your problem without selling you a system.

As far as the uni-steer goes I have read on various boards about geometry problems and header clearance issues.

Cap. I've read about bad welds numerous times and piss poor customer service. If you look around this site you'll find a thread about a member having a cap frame crack numerous times and the frame not being square. There is a thread about a set of their upper arms breaking at the welds right now over on Bbd. Read others have had no problems with their uppers or lowers. Me, I just couldn't trust cap from what I have read.

Go to numerous boards and I'm confident the only one you won't read anything bad about is the alter-k. The product and customer service is second to none
