Nick - The theory is that the shock extension is supposed to stop the lower control arm before it contacts the frame. However, this is only a theory as I have seen this type of damage on many cars, including Winged1. I suspect that aftermarket shocks may contribute to the problem, as well as worn bushings at either end of the shocks. If you are completely stripping and powdercoating the frame, it would be nice to change things a bit to eliminate the interference. Unfortunately, the forward tow hooks are right there, so simply trimming the frame might not be the best idea. If you could get your shop to move the tow hooks inboard a bit, a *smooth* trim on that edge would be okay from a structural standpoint. Another problem with this interference is that it creates a "close couple" (think nutcracker) on the lower control arm, which can bend the arm easily. This can be a problem from a fatigue cracking perspective if the arm is crushed locally from contact with the frame. Let us know what you decide to do.

This over time has slightly bent the area/frame edge were they rest on. Is this normal or are they ment to stop slightly short of the frame, limited by the shock travel? I ask this as i am getting my frame sandblasted & powdercoated soon and dont want to damage the new powder coat around that area. > > thanks Nick 10927-sydney To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
