I had Monroe (cheap stuff) on the car and it wouldn't hold up the car (part of my problem why my wheels would rub on the fenders; If your car does this you should consider the GT Coil Springs, works phenomenal! ) I then got some other cheap end stuff and it just wouldn't do the job! So I ordered these and I've been happy since then. My 1965 Mustang has perfect stance now. She's a beauty.
