Common questions
How do I know the 27mm shank is right for my car?
Measure one of your existing bolts from under the seat to the tip and match it. Too short and you lose thread engagement in the hub; too long and the bolt can bottom out before it clamps the wheel.
Do conical seat and ball seat bolts interchange?
No. The conical taper has to match the wheel's bolt holes to center the wheel and hold clamping force. A ball seat bolt in a conical hole will not seat properly, so check the seat on your current bolts before ordering.
