I recently acquired some nice pieces of front suspension and brakes from a good friend. I got some upper and lower tubular A arms that are made for springs or coil overs. I think they are Strong Arm brand? Anyway, I want to ditch the stock springs and go with coil overs. I know that I have a couple of choices from the vendors here on the board. I was looking at the one GNS performance sells at around $700 and the one Gbodyparts sells for about $600. Anyone tried these parts and have an opinion?
