I'm not sure what the diameter is but the front bar is hollow. The after market front bar is solid.Originally posted by 1sickbird
Diameter is not everything when it comes to sway bars. The type of steel that is used is more important. 4140 chrome molley would be better than mild steel. I even saw someone making an aluminum bar to "save weight". It would have to be like 3" Diameter out of 6061-T6 to be as solid as a 32mm 4140. A 35mm hollow bar is not going to be as stiff as a 32mm solid bar.
I couldn't believe the difference it made putting the BMR sway bars on my car. It really increases the

The stock rear sway bars on my Formula where 19mm (3/4") and replaced them with the 21mm (About 7/8") and made a world of differance in the handling. The WS6 might have a 21mm rear bar.

The 1LE package has:
Front: 32 mm
Rear : 21 mm
Stock:
Front: 30 mm
Rear : 19 mm
If you're going to upgrade them, You should replace BOTH sway bars at the same time.

30mm front, 19 mm rear on T/A or Z28Originally posted by 1sickbird
32mm front, 21 mm rear on WS6 or SS
Aftermarket usually offers a more rigid bar, enhancing the anti roll characteristics.
