Camber and Toe Adjustment Kit

The Stillen SPC Adjustable Rear Control Arm Kit (72240) is a performance suspension component designed to provide comprehensive rear-end alignment adjustability for select Infiniti models. This three-arm set enables precise tuning of camber, toe, and wheel setback, making it ideal for enthusiasts modifying their vehicle for stance, track performance, or correcting alignment issues after ride height adjustments. Each kit contains one set of arms, with one kit required per wheel. Engineered in America by SPC Suspension, a recognized leader in adjustable alignment parts, this kit is constructed from aircraft-quality materials for durability and strength. The kit provides a generous adjustment range: ±3.0° for camber, ±3.0° for toe (beyond the OE cam), and ±1.0" for wheel setback, allowing for customization to achieve desired alignment specifications or maintain factory wheelbase. Installation of this kit requires approximately 1.0 hour per side. The manufacturer advises that the sequence of arm adjustments made during installation is extremely important for proper system function. This kit is specifically designed for Infiniti Q50, Q60, Q70, M35, M37, and M56 models.
