Some race rims have thicker centers so that your stock studs won't extend far enough through the rim. Allstar wheel studs are available in longer lengths to resolve that issue—and do require the re-drilling of your stock flanges for larger thread sizes. Always check with your sanctioning body for proper wheel stud requirements. Order the stud set length and thread size needed for your application.
