This is the bar we developed for the One Lap Camaro. It is designed to work with a 3 link or 4 link suspension that uses a Watts link. We made it in 1" diameter for the One Lap Camaro, but can also make it in 7/8" or 3/4" diameter. It has 6 hole positions for adjustment and is made from heat treated 4140 chrome moly steel. The 1" diameter version is being released as Hellwig p/n 5867 in January 2011.
