The factory rear camber arms are designed for comfort and reliability — built from stamped metal with spot-welded construction — and are only suitable for daily use without offering camber or toe angle adjustment capability. These adjustable control arms replace the factory rubber-bushed units with M3-inspired monoball bushing technology, delivering sharper handling, more immediate suspension response, and full adjustability for camber and alignment tuning. Engineered as a direct OE+ quality replacement and finished with anti-rust anodized treatment for vibrant color and long-term corrosion resistance.\n\u003c\/p\u003e\n\n\u003ch6\u003eFeatures:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eLightweight and durable construction – CNC-machined from billet aluminium and bearing steel for superior strength-to-weight performance and precise dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eCNC machined precision – ensures perfect fitment to factory mounting points with no modification required\u003c\/li\u003e\n\u003cli\u003eAnti-rust anodized treatment – main connecting rod structure is anodized to improve corrosion resistance while delivering a more vibrant, premium finish\u003c\/li\u003e\n\u003cli\u003eOE+ quality monoball bushings – each arm incorporates a single-ball bushing with dust cover and self-lubricating design for extended service life compared to bare monoball alternatives\u003c\/li\u003e\n\u003cli\u003eM3-inspired performance design – takes direct inspiration from the M3 control arm geometry, replacing factory rubber bushings with high-performance monoball technology for sharper handling response\u003c\/li\u003e\n\u003cli\u003eFully adjustable structure – provides camber and toe adjustment capability for performance alignment, lowered suspension setups, and customized handling characteristics\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eSpecifications:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eCondition: 100% Brand New\u003c\/li\u003e\n\u003cli\u003eType: Adjustable Rear Upper Control Arms with Monoball Bushings\u003c\/li\u003e\n\u003cli\u003eMaterial: Billet Aluminium \u0026amp;
