KSP Performance 15mm (0.59") 5x120 hubcentric wheel spacers are built to dial in a flush BMW stance while keeping fitment tight and predictable. Pushing each wheel outward 15mm helps reduce inner rubbing against suspension links at full lock, adds clearance for wider tires, and sharpens handling feel with a wider footprint. The hubcentric 72.56mm center bore is designed to seat on the factory hub for better centering and less chance of vibration compared to non-hubcentric spacers. Spacers are CNC machined from 6061-T6 billet aerospace aluminum and anodized for corrosion resistance. This set includes 2 spacers plus 10 pcs 40mm M14x1.25 lug bolts made from heat-treated SCM435 steel with black Dacromet coating and a 60° cone seat to match most OEM-style wheels. Fits many BMW 5x120 models such as 1/2/3/4/5/6/7 Series and X3/X4 (verify chassis and wheel specs). Always confirm fender and suspension clearance, ensure proper thread engagement, torque to factory spec using a 17mm wrench, and re-check torque after initial driving.
