Since removing my JBR RSB due to excessive ride harshness, I've been searching for a replacement to tighten up the rear that's not so stiff. I had recently noticed that the Corksport, JBR, and Ultra Racing RSB's are the same for the Mazda 3 and 6. A clue. I started browsing some 3 forums and saw a lot of positive reviews for this bar from Progress:
Progress Technology: Anti-roll bars, sport springs, coil-overs, camber kits and more since 1995!
It's apparently almost as stiff as the Corksport bar, but doesn't have the CS bar's dreaded clunk (which mz3 owners are reporting as well). I actually like that it has beefier mounting brackets that are not as obnoxious as the billet pieces from JBR and CS. Those JBR brackets were a pain to install and probably added to the harshness of the ride.
Anyway, I ended up ordering the Progress bar for $145.33 shipped and am very happy about it. They look to be out of stock at several places, so who knows when it will arrive. Just wanted to get a post up here for anyone else that wants to take a chance (which looks to be a slam dunk) on this bar in the meantime, as it will probably be a few months before I get it installed.
