PIU rear sway bar

[speedracer05]

I have the PIU sway bar (you can see it in my pic of my newly installed diff brace). The difference is even greater compared to the OE 20mm bar on my Platinum. For me, it's not enough. I would say it makes "some" difference. I think the @jrgoffin has better results because he also has the struts.

I did have the matching PIU struts and it was a decent improvement. In any case, I sold my ST last fall but know the new owner was impressed with the upgrades.
