I need to space my rear draglites out 1/2" for clearance issues and a wheels spacer would do it. Are wheel spacers legal?
Here is an online link to the 2008 NHRA rulebook. Start on page 31 for general regulations. I breezed thru it and didn't find much about them. Main concern was proper thread engagement in the lugs. By personal experience, they tend to frown on the eccentric stud pattern type of spacer, since those can be out of center if you aren't careful installing them. Your wheel can loosen up and bad things tend to follow. This was emphasized in Funny Car last year when one car's wheel spacer wasn't aligned correctly and resulted in a crash.
as far as I know spacers are legal 1/2" and under (i think) and they must be solid all the chassis guys sell em........I run 1/2 billet ones we made and no one has ever said anything I run top sportsman........ERIK
I'm everything they say i am......I'm so bad......Baby i don't care!!!
you can run them. But you need to install longer wheelstuds.
