Description Videos Reviews The H-Sport (Hotchkis) Competition Rear Anti-Roll Bar for the MINI is designed for the highly competitive road course and autocross driver to reduce body roll and improve handling. You get a lightweight adjustable tubular rear (3-position) anti-roll bar with greasable polyurethane bushings and bushing brackets that have 90-degree zerk fittings for easy lubrication. All H-Sport Anti-Roll Bars are CNC-formed with forged ends. This is the best bar on the market; it's also the lightest bar on the market. Anytime you add weight to the car, it makes it slower. Whenever you can remove weight from the car, the engine can use the power it's making better; so it has less weight to move, and in turn goes faster. There are also no welded areas to break off due to rust because of bad powder coating as we have seen in other bars. Don't be confused when we say 25mm. It's the same as other 22mm bars, but pounds lighter because it's hollow! This is the single best suspension mod for any MINI. We highly recommend this mod for everyone from the daily driver to the track rat! Put this bar on, set it to the middle hole, and have fun! There are no downsides to this mod at all. Always in stock ready to ship or install!

Posted by Sebastien Rott on 20th Mar 2017 I installed that bar an Saturday and went for a ride on Sunday with some friends. The car feels like it was on rails ! In the middle setting there is almost no roll. I really recommend that upgrade. 5 YEE HAWW!! Posted by Unknown on 5th Jan 2016 Buckle in and motor hard. This RSB works. I can't tell it's there till need it, then its does the job. Back end follows the front, just like others say. Easy install, quality product, does the job. If you want an RSB, get the Hotchkis 25mm competition RSB. 5 Believe the hype! Posted by David Rogers on 5th Dec 2015 Installation was straightforward enough (although I would add a rubber mallet and a pry bar to the manufacturer's list of required tools) for even a novice mechanic such as myself. What I actually had to do to get the stock bar out and the H-Sport bar in varied slightly from Hotchkis' instructions (I'm not sure if that's because they were written for either an R53 or R56 and I have an R55…) and the upgraded bar is a TIGHT fit, but everything went smoothly. Taking it out for a spin afterwards was amazing! On the middle setting, corners felt MUCH flatter--barely any roll at all. Feels great! I've always heard that a rear sway bar upgrade is one of the best purchases you can make for your MINI and now I'm a believer. I can't wait to hit the twisties to give this thing a real workout!
