    SKU: KTA255 Benefit Note:
    Whiteline KTA255 for the BMW 1 Series, 3 Series, X1 and Z4 is a set of 4 arms to solve any front end issues you may have. Due to the high performance of many BMW models, the original rubber front control arm and radius arm bushings tend to take a beating, and have a limited service life. In addition many owners will lower their BMW with a lowering kit or coilovers and may have a front end geometry issue that needs correcting. For ease of fitment these alloy arms also come complete with adjustable synthetic elastomer bushings. These facilitate +/- 0.5 deg camber and separately caster. These two key alignment angles can help ensure you get the car set up for minimal tyre wear with maximum grip. The bushings are designed with internal knurling to ensure a reservoir for long-term lubrication with the supplied, extreme pressure molybdenum disulphide (LM) based grease for extended life. High strength ball joints are included with the arms to make this a fit and forget purchase compared to the short service life of the original and cheaper aftermarket alternatives.
