Popping from subframe connectors? I bought my WS-6 bone stock about a month ago with 32K miles. The first thing I did was the strut brace and subframe connectors (bolt on, to be welded in time). Since the install, from time to time I hear a loud pop from the passenger side. It sounds like it comes from the rear bolt, close to the trailing arm(?). It does it on hard bumps, whether I'm moving fast or slow. If I've got my foot in it, then it will pop going over smaller bumps that it normally wouldn't. I've checked and everything is/stays tight. The first time I heard it, I thought one of the bolts snapped off. The car has not been wrecked. Anyone else experienced this?

I installed some bolt on UMI subframe connectors and had the same problem with my spohn poly/poly LCA on the passenger side. I tightened the sh*t out of the LCA bolt, no luck. I had the SFC welded in, no luck. I changed the poly/poly LCAs to rod/rod, problem solved.

Not if the LCA is the one doing the popping. If the sound is there unwelded it will more than likely be there welded since you aren't applying any additional force to the LCA mount by welding it. Welding it in could even keep you from applying any more "clamping force" to the LCA bushings. Right?

I had the same problem when I had subframes on my V6 Firebird. Stock Lcas, BMR Subframes weld in. But it was the subframe actually hitting on the rear floorpan. Took awhile to figure it out, just bent it up a little bit and the popping was gone. Might have just been a fluke but just my .02
