The best solution for solving the
premature E46 front bushing wear problem!
The Powerflex E46 Front control arm
bushing is one of our #1 selling products. The factory rubber
bushing is a delicate piece that wears prematurely, creating sloppy
steering, bad inner tire wear, and a jolting steering wheel under
braking. Instead of replacing this bushing set with factory
bushings every 40k miles, we suggest upgrading to the Powerflex
urethane bushings for a long lasting upgrade that will increase
steering response, reduce uneven tire wear, and reduce maintenance
These bushings add minimal, if any,
NVH (Noise, Vibration, Harshness), and are suggested for street
dedicated cars and auto-x/ driving school cars as well*. One of the
best features of these bushings is their 2 piece design. The
bushings are made in 2 pieces so the rotation occurs between the
urethane for a squeak free, easily lube-able bushing with a
considerably increased lifespan. The inner bushing is grooved to
hold the copper based lube (supplied with kit) for numerous
A set includes 2 bushings
and lube for a complete kit. No other
parts are necessary. If your E46 has more than 90k miles, we
suggest taking a hard look at the front control arm's ball joints
for wear as well. Any movement at these ball joints can produce bad
tire wear and handling.

they were installed within 2 hours and the steering is great!

Just bought my 04-325xi and took it to mountains. Had a violent shimmy under heavy load during acceleration, and if i hit the brakes i would practically change lanes. I put these on, took me about 4 hours, and not the car tracks and brakes like its supposed to. Unfortunately, there is not an online instructional for the install so you had better have the factory manual and some good mechanical experience. Next project is the rear trailing arm busings replaced with Powerflex.

Phenomenal Upgrade for EVERY Bimmer!
From Nick of Cincinnati, Ohio on 8/2/2012.
PROS:- Improved steering response and feedback- Incredible durability, no loss of steering response over time (at least 4-5 HARD years)- Very easy to install- Available with housing in 66mm version to upgrade earlier E46's- Does not make the car more prone to "tram-lining" like some of the other FCAB's I have tried (offset ones are the worst)- Are a PERFECT complement to either Genuine BMW ZHP/M-Sport OR Meyle HD (ZHP-type) Front Control Arms- 2-piece design and interior "lube channel" means that under duress they will be able to twist and not tear- Design also means that they are absolutely SILENT if properly installed- These are PERFECT for everything from a daily-driven commuter car to high-horsepower track/autocross (yet still street-legal and street-driveable) cars, and I use them on both!CONS:- Pricier than OEM, but not really a con as it is a one-time cost- The higher cost may not be beneficial if you don't intend to keep the car for more than a few years- I would STRONGLY suggest purchasing new, upgraded Front Control Arms to go with these as the OEM FCA's have outer-ball joints that fail and cannot be replaced (Meyle HD can)- THEY WILL SQUEAK IF INSTALLED IMPROPERLY!! Don't go light on the grease, use the entire amount between the two bushingsHonestly, I had to really stretch to think of any cons.I have used these on both my '00 328Ci and '01 325i, installed both times during a full-suspension upgrade (TC Kline Race/KW Variant 3 Coilovers, Hotchkis F/R Adjustable Swaybars, ZHP/MeyleHD FCA's, TMS Full-Reinforcement Kit, TMS Adjustable Rear Camber Arms, RE "Race" RTAB's, UUC "Race" Trans/Engine Mounts, PowerFlex Subframe Bushings, TMS Semi-Solid Delrin/Aluminum Diff Mounts/Bushings, Adj F/R Swaybar End-Links, Meyle HD Tie Rod Assemblies, TMS Rear Upper Inner/Outer Trailing Arm Bearings, TMS Rear Inner Upper Control Arm Bearings, all-new wheel bearings/hub assemblies, a custom Quaife 3.25:1 Variable-Locking Limited Slip Diff with Rogue Finned Aluminum Cover (328Ci), 6spd Manual Trans from '05 330Ci ZHP swapped into 328Ci, UUC Dual-Mass Clutch/LTW Flywheel Kit (25lb total) for 328Ci/UUC 9.5lb Flywheel + M5 Organic Clutch for 325i, new Guibo and Driveshaft supports, UUC EVO3 SSK/DSSR/Clutch-Stop/Clutch-Pedal Bushings/SS Braided Clutch Line, Brembo 6piston/4piston Monobloc BBK/StopTech Stage2+ 4-Wheel Brake Upgrade Kit w Slotted Rotors, and so on and so on).I have gone through a great deal of parts and my garage looks like a BMW Aftermarket-Parts wholesaler warehouse, but I have never one had to change the Powerflex Front Control Arm Bushings!!! The 328Ci is driven HARD, with a heavily-modified ESS TSE2 intercooled twin-screw supercharger kit and fully-built engine, it not only puts down 400hp at the wheels, it spends a great deal of time at the track or at autocross events. Since I have installed the PowerFlex FCAB's (+housing) in my 328Ci over 4 years ago, I have gone through 12 sets of tires (Pilot SuperSports/PS Cups mostly) even with custom flared fenders to allow for 19x9.5" front wheels and 19x11" in the back (usually fitted with 255-width front tires and 275-285-width rear). There is literally not a single piece of stock suspension left.So, about 3-4 months ago, I took out the PowerFlex bushings to inspect and re-lubricate if necessary....THEY STILL HAD AT LEAST 90% OF THE ORIGINAL LUBRICANT APPLIED WHEN INSTALLED! There were no tears, the rubber was still compliant and no hardened, and I honestly could not be more impressed!

Used compelte kit installed by professional, made all the difference in the world, holds road better and no longer makes noise and pulls when applying the brakes. Also had complete alignment done.
