Thank you. You have rated this product.

This is for #4 in photo ONLY. Rear Beam to Chassis Bushing, Includes both driver and passenger suspension bushings.

Powerflex polyurethane bushings are designed to decrease the amount of deflection in your car's suspension for better handling, driver feedback, and tire wear. We use a premium polyurethane formulated specifically for our company to provide minimal NVH (noise, vibration, harshness) and increased longevity over the stock rubber bushings.

The quality of Powerflex products is visible the moment you open the box: premium polyurethanes, detailed moldings, and CNC-machined 304 stainless sleeves. Lube-holding grooves and knurls will ensure the supplied copper-based grease stays in place for extended squeak-free operation.

Powerflex products carry a Lifetime Warranty on every part produced.

Powerflex is a truly engineered product, not just a copy of the stock part in a different material. We have redesigned many common factory failure parts, allowing the articulation required to far outlast the stock part it is replacing while maintaining control of the movement for increased performance. Additionally, Powerflex Engineering Line products for some fitments include unique features like polyurethane monoballs and offset geometry to provide ultimate performance without the harshness of a metallic monoball race part. Polyurethane engine/drivetrain mounts and reinforcements are available for some fitments to reduce movement for better throttle response and more power to the wheels.

Bushings are produced in one of three durometers yellow (70A stiffer than rubber), purple (80A), and black (95A very stiff) measured hardness. Unlike other brands using only one urethane for all applications, Powerflex design engineers choose the correct hardness to allow for the specific movement or rigidity required for each location while minimizing unwanted NVH. Urethane hardness is standardized per fitment and location, but select parts are available in an optional stiffer urethane for track and autocross performance where NVH is less important.

Powerflex bushing offerings are very thorough, but are sold per location to fit each customer's specific needs. An automobile's bushings and mounts wear at different rates making "complete-kit" bushing sets unnecessary for most buyers. Replacing only the weak links in your car's suspension is a great way to tighten handling without stressing the budget.

Powerflex copper-based grease is supplied with every bushing set. We suggest using only a copper-based grease for lubrication. Bushings will rarely need re-lubing due to the unique grooves and knurls cast into the material to hold the lubricant. We do not suggest using an "anti-seize" product for lubrication.

RE: RoadsterSport Stainless MX5 Miata Midpipe Part# 60-1328: I love the mid-pipe!! Not only is it beautiful, but it makes the sounds coming out of the 'race single' exhaust even better. The two go well together, and it mellows the decel drone a lot. I'm very happy with my purchase.

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.
