OK so for our pack race, we used some wheels with coned hubs. The district race coming up does not specifically outlaw them, but I am taking a set of regular wheels with us just in case. How much benefit do the coned hubs usually give? I realize there could be a reduction in friction, but I'm not sure how much it's going to affect the car if it does not have the coned hubs. Also was considering putting high gloss decals over the axle holes, and punching thru them with the axle, so the lubricated hub slides on the sticker, not on the paint of the car, seems like it would be less friction that way as well.

The benefit is not in friction reduction, but in reducing the contact patch. Friction is independant of surface area. (not intened to open that can of worms) Placing high gloss material around axle hole may be of some benefit, be sure to lube it. Also take care when "punching" through no material gets in hole, otherwise you have a shim distorting the axle alignment. Better yet align wheels to stay off body!

A properly aligned rear wheel should float on axle near head but not on it. For insurance you can camber wheel 3 degrees, this will insure wheel rides on axle head rather than body.

OK, and this can be done with a simple bend of the axle? Sorry if I am not gettign all this right away, I have absorbed so much info in the last 3-4 months, it's insane, and trying to put it all together is a challenge in and of itself.

Fatdaddy:
Yes, bending an axle is one way to camber the wheels 3 degrees. Another would be to drill the axle holes at a 3 degree angle. Tough to bend them equally, but not much easier to drill them at uniform angle. If you are using the axle slots you can camber using wax paper shims, but those are your best options.

ProQuest/Steve H. I have a pro body tool (works awesome, by the way) that's how I got the axels in before. I think I will just let it ride this year and see how he does, rather than try to camber now, and save it for next year. I was considering notching the front axle slots to ride the rail, but I'm going to attempt it on my car first so I dont ruin his for no reason. |
