Not, not *my* nuts (see off-topic thread for info there!), the car's lug nuts.

I'm a bit confused as to whether I need extended or regular. I'm going to be running on RPF-1s that are 18x9.5 + 15 in front, and 18x10.5 +15 in the rear. I only ask because I've seen some comments on the board about people getting the wrong length nuts, etc. etc.

Any advice would be greatly appreciated. Thanks, people.

 

Generally no. Wheel size and offset does not effect stud length. Look at the offset diagrams above: the wheel to hub mounting surface is not altered. Most after market wheels require a 60-degree conical nut like above.

 

Okay, so to go with that.... I have some McGard splinedrives that I used to have when I owned my Civic. Is it likely that these would fit? (I'd go out and try this right now except the nuts are actually back on the east coast at my parents right now).

 

No, honda's use a different thread pitch

 

Okay, that's what I needed to know. Thanks, guys.

 

I believe we are M12/P1.25, I do not believe the Hondas are that size.
