Easy to lubricate polyurethane bushings and heavy duty brackets with zerk fittings included. Designed and manufactured by Hotchkis Sport Suspension specifically for the 2004-11 Mazda RX-8.

Our street, autocross and track ready Sway Bar package features our extensively tested 33mm 3 position adjustable front bar and our 21mm 3 position adjustable rear bar for drivers looking for a distinct street, track and autocross handling advantage. Polyurethane bushings and heavy duty bushing brackets are also included along with zerk fittings for easy lubrication.

The Mazda RX8 in stock form is limited by excessive body roll and understeer. For ultimate speed, and due to the limited Rotary engine torque, cornering momentum must be maintained. Bolt on a set of Hotchkis Sport Sway Bars and gain true handling performance and increased cornering momentum.

ENDLINK NOTE! The front bar at the stiffest setting when used with endlinks that have a protruding top bolt that connects to the bar (in my case the Agency Power front links) may contact the dampers.

After reading many other positive reviews on both the GWR and Miata forums I finally decided to buy this product. My main concern for many months was whether or not I was up to the task of installing the header. But with the excellent instructions on Brian's forum as well as several Miata forum threads it turned out easier than I expected. After receiving notice that the header would arrive on a Friday afternoon, I began the disassembly process. After about 3 hours I had the stock manifold out. Later that afternoon the new catted header arrived right on schedule. And it is a thing of beauty. I opted for the stainless version. Installation on Saturday morning took another 3 hours, although I could have shaved some time off of that but I was actually enjoying the process of double checking torque values and cleaning up my engine compartment. I already have the GWR catted midpipe, so that connection was a snap. I put everything back together, reconnected my battery, and went for a drive. NO CODES! Nice throaty sound with my RSII muffler, and a significant boost in power and low/mid torque. Another happy camper here. I since have added a M-E tune and I feel I have realized all of the gains that Brian has achieved on his 2012 project Miata. I've put several hundred miles on my Miata since the install with zero problems. This is the car that Mazda should have built all along. Thanks Brian.

Hi Brian, I just bought a heatshield and a cruise control relocation bracket for my '95 Miata from you. It is in the mail now. Thanks for such fast service. (My cruise is just wrapped up in a microfiber shoprag at this time!)
