Sonoma is the perfect wheel for those that want to emulate Formula 1 Race Car styling onto their vehicles featuring a TSW exclusive locknut. This center locknut system was originally seen in the famous TSW Hockenheim R and EVO R and has now been updated for 2018 utilizing injection molding technology. This cap cover system protects the lug nuts while creating a clean look for any vehicle. Sonoma utilizes five spokes to ensure proper vibrational harmonic load while the wheel is in rotation and is casted to the high quality standards of TSW. Sonoma is the perfect choice for the smart wheel buyer that appreciates quality, engineering, and styling.
