Powerflex High Performance Front Control Arm Bushings have advanced engineering and materials compared to standard urethane replacements. Powerflex mixes design elements from racing with a carefully-chosen urethane hardness to produce this impressive E46 FCAB. These bushings are in the offset orientation - they add more caster and camber to cars that originally came with centered bushings.
This set of 66mm control arm bushings fits E46 3-Series non-M rear wheel drive models (1999-2006) and all E85/E86 Z4 models (2003-2008).
Powerflex builds this control arm bushing with an aluminum housing that is light weight and obviously very strong. Two urethane bushings are available: purple 80A for street and black 95A for ultimate precision on the track. Each E46 bushing is an eccentric orientation to add slightly more caster and camber - caster increases by 0.5. This improves steering and adds dynamic camber (this version will also move your wheel forward slightly in your wheel well).
Powerflex has extensive experience in automotive suspension and chassis systems and has combined these skills with advanced polyurethane manufacturing techniques. Bushing durometer (stiffness) has been carefully selected for specific uses:
Street Performance for slightly more sport and precision in daily driving environments. Urethane material for less deflection, more precise handling, and better steering response but while retaining some comfort for street use. No track or very little autocross. If you attempt to use these in competitive driving you will quickly be outclassed by others with true race equipment.
Track/Race-only is for dedicated track cars that are never intended to be driven on the street (you might throw a plate on it and run to the store). Basically, if your car has racing harnesses instead of seat belts. These will be the stiffest urethane or Delrin for near-zero deflection and extremely precise alignment settings. NVH and comfort is not a factor in the engineering of these bushings. Our preference is for Delrin over Black urethane for track use.
Note: Powerflex copper-based grease is supplied with every bushing set, and they will rarely need re-lubing due to the unique design features built into the material to hold the lubricant.
