It fits. I never gave the car a real shake down before installing it so I can’t say exactly how much difference it will make but doubling the bar stiffness should help it rotate. I’m trying to prep for street class as much as possible before my first event in a few weeks.
Great news. Let us know how the car behaves now when pushed hard . Curious to see if its a bit too much or not as I've heard upgrading to a thick rear sway can cause you to spin a little too easily.
