I'll provide part numbers and driving results.

Awesome, I have been looking at the ss sc1 up grade. I think it is same as. fe4. Non adjustable with front end links.

Actual gm fe4 bars? if so they are 30 mm hollow front and 27 mm solid rear fyi.

The sway bars are installed.
To install, I dropped the Borla Atak exhaust and disconnected the front steering electrical connections to swap the bars.

The bars fit perfectly!

The rear bar is 9 pounds heavier. The FE4 front bar is not much heavier but is approx. 1/4 inch larger diameter over the FE2.

The change in the front roll before/after is approximately from 4 inches to 2 inches.
The test was driving in a circle until the roll stabilized.

The bars improve the handling.

Parts Used:

Sway Bar End Links Front - BMR ELK016
Sway Bar End Links Rear - BMR ELK017
Stabilizer Bar Front - FE4 - GM 84458196
Stabilizer Bar Rear - FE4 Convertible - GM 84118919

The link holes are the same size; however, the Stabilizer Bar Rear - FE4 Convertible - GM 84118919, is for the Convertible NOT the Coupe. The rear bar is not straight and bends around additional chassis bracing.

GM Part Numbers - FE4 and FEA Rear Sway Bars
FE4 = AJ37, AK37, AL37 [SS 1LE and ZL1 coupes] = 84026864
FE4 = AL67 [ZL1 convertible] = 84118919
FEA [3 Adjustable Holes] = AL37 = 84218218

GM Part Numbers - FE4 and FEA Front Sway Bars
FE4 = AJ37, AL37 = 84052981 or 84458196
FEA = AL37 = 23332961

Great info, I think I will try my rear end links with fe4 bar.

FE2/FE3/FE4/FEA all use the same rear end links, so you will be fine. It's only the front end links you need to upgrade (I went with the OEM parts that the FE3/FE4/FEA models share).

Thank you, I stuck my hand through the wheel and felt of them. They felt thick.

Update: I've done a couple canyon runs with the FE4 front bar and FEA rear on medium, and there seems to be a hair too much understeer and rear body movement. So, I'll be moving the rear bar to its firm setting, which I expect should yield a well balanced setup.
