I did mention you and he said... and I paraphrase "yeah but he is running a HUGE tire!" Haha! He did say that I should be running my rear bar at the softest setting (currently on the hardest and love it) and adjust from there as needed...make sense to me. Anyway I hope he is right... we'll see. Thank for your help and input!

MCS has since decided to offer something off the shelf, which is nice cause I ended up making my own rear top mount and of course i'm still trying to address some squeakiness in the mounts.

So I got the MCS rear mounts. Installed everything, set ride height, corner balanced and aligned. I'm getting a slight cluncking in the rear. Any thoughts on this? Do you have any? Its a litle annoying as it feels like something is gonna break. I know it's somewhat the nature of solid mounts. You said you were getting some squeaking but are you getting any cluncking?

Yeah I was just about to when I got back from the alignment shop but it was already past their business hours. I'll give them a call first thing tomorrow. The two times I've called they were very helpful. I'm hoping it's something I just missed during install.

Also, get the vorhlag camber plates if you do not already have a set, they are worth it. Positive caster ftw.

If you have someone jump on the door sill really really hard, can you hear the clunk? If so get underneath the car and try that. Mine never clunker. Also also, are you running helper or Tender Springs?
