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!
Nearly every car manufactured in the modern era carries a dark secret – fully-adjustable suspension has been all but eliminated in the name of cost-cutting and assembly-line efficiency. What this means for you is increased tire wear and more frequent replacement, as a “full alignment” consists only of rudimentary toe-angle adjustment. For over forty years, K-MAC has been hard at work developing a solution to this problem with patented innovations in camber/caster plates and bushing kits, allowing easy adjustment and a true “full four-wheel alignment” to be performed by any competent shop. These bushings make camber adjustments possible for the first time, and improve the ability to complete toe angle adjustments. When used in conjunction with the K-MAC Camber and Toe kit and Rear Adjustable Trailing Arms allows full adjustability of the 5 multi-link rear arms and positive location. Bolt-on installation – insertion/extraction tube included! Easily adjusted on the car with basic hand tools Unique failsafe locking hardware – set & forget! High quality elastomer compound resists binding Hardened & nickel-chrome plated centers for maximum bushing life 2x the load area of stock bushings Spiral grease grooves

Rubber has no place on a race car (except for tires, of course). Rubber suspension bushings are one of the first things to get swapped out for our race cars. The more solid the better when it comes to controlling the alignment and keeping your race setup consistent. We use as much solid material as the rules allow. With no deflection, solid bushings also give amazing feedback to the driver. For the M235iR, BMW had two specs for the rear control arms - stock stamped steel control arms with a rubber/neoprene bushing that is slightly stiffer than stock (2014-2015 spec) and these aluminum/stainless steel control arms with solid Heim-jointed ends (2016 spec). An additional benefit to the Heim joints is the arms are adjustable so the alignment can be perfectly dialed in. The front control arms use M3/M4 thrust arms and wishbones with sealed monoball joints. Full solid mounts and bushings will give you many setup options with razor sharp steering and chassis response. Note: 2016-spec rear control arms do not have a spring perch like the factory arms. These are for rear coil over shocks only.
