Start all bolts by hand and snug them in a star pattern before final tightening, which keeps the wheel centered as it draws down. Finish with a torque wrench set to your vehicle's spec; the torque reference chart covers common applications. Re-torque after 50 to 100 miles, and stash the spline key where you can reach it during a roadside tire change.
Common questions
How many bolts do I need?
Count the lug holes on one wheel and multiply by four. A 4 lug car needs 16, a 5 lug car needs 20, and the 24 piece kit covers 6 lug fitments or leaves you spares.
Can I mix seat types between wheels and hardware?
No. Conical, mag, and ball seats are not interchangeable; the bolt seat must match the shape your wheel is machined for or it will not clamp correctly. Check your wheel's seat before ordering replacement hardware.
