I am looking to add coilovers to my parallels and saw some spring plates at Speedway. Am wondering if there is a stouter or better lower support option out there. With the lowering blocks (I know, I know, Bad, Bad ) that are on there an axle mounted support would move the coilover to high above the Z in the frame. I liked the idea of the coilover mounting plate at the parallel but theirs look wimpy. Anybody have experience with rearend coilovers in conjuction with parallels?
