Actually, according to gtspec there is another blue msp in New Jersey that has all the parts installed (i didn't install the rear strut bar-need my stock amp).
It has been confirmed that the rear v brace bars will clunk with the sway bar if Micaspeed!'s (dave) klunk fix is also installed. My mechanic told me he'll fix it somehow this monday.
so who mentioned to you that with an upgraded exhaust this will still work? i remember researching the 4-point ladder, and finding that you can't use it with a non-stock exhaust because it will hit ..
warrier04- Jayson from revspec said it could work by adding some kind of a cushion between the exhaust and the ladder bar...but I'm not sure if it'll really work. You could always call Gtspec directly to get some more info.
Dave's klunk fix brackets do work to eliminate the clunk, however recently there has been reports of a different kind of clunk associated with worn out endlinks. Also, it's very hard to get this part because of Dave's job (busy).
