On several BMWs, rear control arms are a weak point. Turner Motorsport stocks a variety of replacement front control arms for your BMW. We recommend looking into the OE options we offer to save you money on your maintenance so you have more left over for performance parts!
A byproduct of multi-link suspension arrangements is a dynamic change in the car’s alignment settings- when making an adjustment to one attribute like camber, track width and toe will follow. This is especially true for the E9x cars, as the original BMW camber eccentric bolt has an impact on toe as well. Alignments are made faster and simpler when using a set of aftermarket lower arms, enabling the alignment tech to easily reset toe after adjusting camber. The race toe link kit by Fall Line Motorsports is designed to facilitate rapid adjustments of toe during an alignment, and combined with the tension strut will also enable adjustment of overall track. Not only does this allow for fine tuning of wheel fitment, these arms will allow an alignment shop to make quick work of car setup, even simplifying the camber adjustment process as a result. The race toe links utilize a unique clamp-style fastener system as seen in BMW’s own tie rods and Porsche Motorsport components, tightening the adjustment arm in place with no stretch of the hardware or change of alignment. Less expensive jam-nut designs limit precision and nearly guarantee an alignment change when the jam-nut is tightened. Laser cut lockout washers correctly eliminate the original BMW adjustment, eliminating any unwanted movement in the system.
