My CS is in shop today for RSS bars and links. Will post later with track results.I put a set of RSS sway bars on my car recently and am very happy with the results. Flatter cornering attitude, sharper feeling steering response and no affect on the ride. Haven't been back to a track event yet but I'm very happy with the road handling. Apparently the H&R bars are slightly larger in outside diameter than stock so the installation is a little trickier where the RSS bars are the same diameter so there are no fitment issues at all. All the bars are hollow, the RSS have thicker sidewalls for greater stiffness than stock (same for H&R).
Talk with Tom at Rennsport One, he sells both brands and gives a fair evaluation of both.
Can anyone comment on using the stock drop links with the H&R bars?
I installed the H&R bars almost three years ago with the stock links and never had an issue, I love them.
However, I would recommend installing both bars at the same time and adjust the rear to fine tune your balance, I think you will like them.
BTW I like to use 34psi front and 37psi rear and the hardest setting on the rear for a really crisp response.
