This is the way we dropped American muscle at the shop, there are literally thousands of cars driving around on drop spindles. these just needed a lot of Attention to install them. however after a couple hours of grinding and fitting I have them in the car. the ride is perfect, just like my other factory stock car. they are not a direct bolt on. I wouldn't recomend anyone buy these if you are not really really good with a grinder. it is a Time consuming and expensive way to lower your car, I am pleased with the ride and the steering is tight, absolutely no wander on the freeway at any speed. The drop looks great can just get my fingers between the fender and the tire. got to go put some miles on them now, check back later.
