The rear sway bar is bent in the middle to go around the convertible's bracing.
On the coupe, the bar is straight.
I ordered the ZL1 FE4 Convertible Rear Sway Bar from GM -
GM #84118919.
This is the part they sent and it is too thin. The part is the same part on my 2LT FE2 suspension.
- Diameter - 0.78 inch
- Circumference - 2.48 inch
Can you check the Diameter or Circumference on your SS convertible's rear sway bar?
I was hoping the diameter for the upgrade SS or ZL1 FE4 is 0.98 inch.
Update:
GM initially sent the incorrect rear sway bar. The correct FE4 convertible sway bar received is 0.98" solid.
FE2 to FE4 improved performance.
