Default Rear sway bar diameter

I have a 17mm rear sway bar on my stock 05 would going to a 19mm make any difference? Tks.

yes

normal street driving hardly any difference...at 10/10ths, 2mm probably won't make a huge difference, but you'd tend more toward oversteer and inside wheelspin

I tend to think of the anti-sway bars as a functioning pair. Many feel with OEM C6 tires the Z51 bars are your best bet. IMO if you go to larger wheels/tires upsizing to Z06 size sway bars may be more appropriate. I don't think a 2mm increase will do much. Here's a chart that may help:

So much more to it than the diameter. Solid vs hollow for example. Material used 9stell alloys are not all the same). The bars have a torsion spec to them that is not published.

Best would be to swap the bars and try it.

Where did you find a 19mm bar? Id it adjustable?
