Lincoln Continental Mk Vi Performance Suspension?

I am currently building up my ’81 Lincoln Continental, and am looking for a web site that offers performance suspension kits for the boat. Initially I found a web site 8 months ago but I lost the address. I am NOT looking for an air bag setup, just a plain old coil spring upgrade with at least a 3″ drop. If your wondering why I want to upgrade, it’s simple. This heavy hauler rolls like a tug boat in corners, and DON’T tell me to get a small car if I want better performance. Besides if I wanted one I’d buy one, not many dinky cars are worth much, unlike my luxury linner which was appraised at $6500.00 and possibly more if it was brought to auction.
