my 2012 PP came with one yep it looks cool. For fun I would like to see blind testing done to see if anyone other than a pro notices anything.
Mud's a fan of research and likes to read studies done with Placebo's and know they do work.
When I I was researching the topic with my prior car, I found a video where the strut bar company put a camera under the hood and viewed the play in the struts, then did it again with their strut bar. Not sure how accurate the transfer to lateral G was, as it wasn't measured, but it was cool to see. Either way, if anyone has a go-pro, an accelerometer, and some free time, it'd be a cool study.
