Description
Adding wheel spacers reduces the amount of stud threads available for the nut to tighten down on… the wheel studs used with your wheel spacers must be long enough to ensure that at least nine (9) turns of the nut are completed before securing the wheel to the hub.
We offer standard factory style wheel studs and racing style wheel studs with a bullet-style lead to speed lug nut installation and reduce the chance of cross-threading.Minimum stud bolt length (sp) is calculated using the following formula: New Stud or Bolt length (mm) = Existing Stud or Bolt length (mm) + Total wheel spacer height (mm)
Longer studs may be used with steel open end lug nuts.
