Powerflex subframe inserts are designed to fit into and fill up the voids on the original bushing shipped with the vehicle. This offers an easy to fit, cost effective method of holding the subframe in position and reducing movement when cornering hard.
US Models: Use PFR5-421, not PFR5-423.
EURO Models: PFR5-421 Insert fits all models up to 07/2005, then Automatic models only from 07/2005+
EURO Models: PFR5-423 Insert fits manual models 07/2005+
Ordering one set of PFR5-421, location #20, contains the correct number of Rear Subframe Rear Mount Inserts for one car.
Powerflex bushings utilize the correct hardness for each location while minimizing unwanted NVH (noise, vibration, harshness). Urethane hardness is standardized per fitment and location. Select parts are available in an optional stiffer urethane (The Black Series) for track and autocross performance where NVH is less important.
Powerflex polyurethane bushings are designed to decrease the amount of deflection in your car's suspension which improves handling, driver feedback, and tire wear. A premium polyurethane formulation is used, specifically to provide minimal NVH and increased longevity over stock rubber bushings
Powerflex Bushings are designed to address common factory failure parts, Powerflex bushings allow 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.
Powerflex bushing are sold per location to fit 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. Powerflex suggests 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. It is not suggested to use an "anti-seize" product for lubrication.
