I've had HPM Mega-Bite Jr's on a couple cars which I've liked. I've had LRS economy style LCA's on cars and I've had BBK's. They are alll the same stuff. Poly bushings, boxed sheet metal...not much difference in the parts. Just a big difference in price.
The weight jackers from Granitelli, Steeda and MM are on a whole other level. Adjusting the ride height with an impact in 2 seconds is pretty awesome!
