Common questions
Are conical seat bolts interchangeable with ball seat bolts?
No. The seat is what centers and clamps the wheel, and a conical taper will not seat correctly in a wheel machined for a ball or mag seat. Match the bolt seat to your wheel, not the other way around.
Is a 27mm shank the right length for my car?
Match it to the bolt you are removing. Keeping the same shank length preserves the thread engagement your hub was designed for, while a spacer or thicker wheel calls for added length.
