Vehicle coverage does not override the OEM-wheel exclusion or wheel-pocket clearance requirements. These are not bolt-pattern conversion adapters and are not intended for 5x100 hubs. Do not infer compatibility with other vehicles from bolt pattern alone.
Fitment and Installation
A 15mm spacer moves the wheel outward by 15mm at that wheel position, reducing effective wheel offset by 15mm. Check tire-to-fender clearance throughout steering and suspension travel, along with hub seating and fastener clearance. A wider stance does not guarantee improved handling or clearance on every wheel setup.
Have a qualified installer follow GrimmSpeed's current installation and torque instructions. Clean the mounting faces, verify that both spacer and wheel seat fully flush, and check appropriate fastener engagement and lug-seat compatibility. Do not stack spacers or drive with interference. Follow the manufacturer's torque recheck procedure after installation.
