I'm going a little shorter this month. Would any of the veterans be willing to share their opinion?

I never tell the truth about the length of my hub. Bahahahaha!!!!!

Maybe our resident ace, DH, can provide insight into this question.

Personally, I find it depends on the car. I've had fast cars with longer and shorter hubs. It really depends on your build and your comfort with the different types of hubs.

Ask me about the Mojo Pinewood Academy! If you are interested in reducing the learning curve and learning how to properly build and prep your car, I can help you turn your cars into Hot Rods!

Two wheels that weigh eaxactly the same with same diameter but one has a short hub and the other a long hub, the wheel with the short hub will have more weight/mass distributed further from the center, thus, have a higher moment of inertia that results in slower starts. When shorter hubed wheels are used on fender cars the same applies, however, fenders can be made narrower to match the narrower wheel width. The benefit of having narrow fenders outweigh the negative effect of the higher MOI of the short hubed wheels. Newton's third law is very applicable here.

I have run both the long and short hubs with equal success.

Thank you for the response. I've always hesitated asking questions here because I didn't think the veterans would respond. I'm finding that isn't the case

Makes it easier to clean up the polish.
