DESCRIPTION
Improve your BMW's handling performance, steering precision and gearbox shifting with a Powerflex PFF5-4650 bushing. PFF5-4650 and PFF5-4650BLK fits models in Position #50 in the Bushing Position Diagram below.
Why have only one engine mount? The Powerflex Tuneable "Hybrid" Urethane & Aluminum engine mounts for the E36, E46, and E90/E92 M3 are configurable to match your current car spec. It's "tuneable" to multiple performance settings -
- Street Performance with a dual-urethane core (65A and 80A bushings)
- Track Performance using stiffening pins inserted into the mount. The mount does not need to be removed to insert the pins, making this a tuneable mount from the paddock.
Also available is a full-race mount with a 95A black urethane core and stiffening pins. With the stiffest configuration the Powerlfex mount is a whopping 675% stiffer than a new M3 engine mount!
Other BMW urethane engine mounts are made with a single solid urethane block of one durometer. This is simple and cheap to manufacture but is not ideal for most scenarios - the mount is either too stiff or not stiff enough and poor manufactuing quality leads to continued problems. Powerflex properly engineered their mount to absorb vibrations while providing exceptional strength and sheer resistance. The design uses a "soft" Red 65A urethane to absorb Noise, Vibration, and Harshness (NVH) with a stiffer Purple 80A urethane for improved strength and performance. If you desire a stiffer mount for tracking or drifting the mount can be made stiffer without removing it from the car! Unsnap the yellow retaining collar and insert the four stiffening rods. This reduces deflection in the mount and makes it stronger.
Why would you want a stiffer engine mount? Mounts need to be stronger to withstand the higher stresses seen with hard driving or launching. Less deflection in the mount means a failure is less likely. The stock mounts are too soft for these types of driving and it's not uncommon for rubber mounts to break apart, mounting studs to shear off, and for the engine to move around and contact other parts (the radiator for example). Stiffer mounts help prevent these issues as well as giving better engine response, quicker power delivery, and more precise shifting (reducing the chances of a mis-shift). The beauty of the Powerflex tunebale mount is that it can be adapted for changing conditions, unlike other urethane or solid mounts which are either too stiff or not stiff enough.

PRODUCT WARRANTY
PowerflexUSA's limited Lifetime Warranty reflects confidence in both their products and also the history of fanatical customer service.
PowerflexUSA does not have a time-based warranty policy because issues that customers have are always an opportunity to learn. Where a problem has occurred due to incorrect fitting, we have always asked if the reason for the error was due to poor fitting instructions. When a part fails, we strive to understand if the part is being used outside of its design parameters. And like all manufacturing we have had the occasional material quality issue and in these cases, we have always replaced parts without question.
For warranty service please see the below instructions:
- Contact Powerflex USA directly via their online Warranty Page.
- Note the ViVA Performance Order ID associated with the bushing; including details of the installation and any changes made, with photos of the failed part.
- The Warranty only applies to parts purchased from ViVA Performance.
- The Warranty is limited to the replacement of suspension bushings supplied.
- There is no Warranty coverage for consequential part failure or labor for installation.
- The Warranty applies to the original purchaser only, no exceptions.
