I added some supports on the bottoms that tied the lower arms together while getting rid of the factory flange if that's the right word for it and did the same to the upper but didn't add any extra gussets. They are around 15% lighter than stock.
Most people are reluctant to do that. I've modified suspension parts before but for drag racing mainly where there aren't any pot holes etc. The old track I used to run had a pretty lousy return road so had to be careful going down that thing even with stock stuff lol
Years ago when they were first introduced, I installed the chrome-moly non adjustable Magnum tubular upper A-arms. They saved a pound on each side.
Think I got about that much off of the stockers. I just weighed them before and after but didn't write all this stuff down. I'll just be happy to keep my tub below 3000 lbs once it's back together. I could really tell the difference in the way it handled getting 400+ off of it. I lowered it and stuck on 225-75-15's mounted on 7" cop car wheels then did an alignment with enough camber that you could look close and see it....it surprised me that it handled pretty dang good for not having sway bars on it.
