Anyway took the car to Detroit and back for Bbomg5 now the car is 100 times worse cars moving a lot out on the road def not cool.
1SS 76 mil turbo
Pfadt springs 1.25 drop
Sphon tunnel brace
BMR trailing arms
BMR toe rods
BMR full poly subframe bushings
9 inch forgestars 11 inch rears
Pfadt sway bars front and rear
Stock end links
Cars alignment is perfect tire pressures fine
Not a balancing issue bc them it would vibrate and shake
Is it the poly subframe bushings ? i have heard they move.
Any help or ideas would be greatly appreciated
There is no reason to gues at this.
If you think the rear sub-frame bushings are the culprit use a GoPro or similar camera and get a bit of video on the rear sub-frame bushings. Post it here.
If that isn't conclussive we'll point that camera at a few more critial locations until we isolate the issue and identify a fix.
