I just purchased a set of Edge Super Stocker 1g. wheels, and am looking forward to running them for the first time. Here is my question, I usually run BSA wheels lightened to about 2.7g, with about 1/16" body/hub spacing, is this too much spacing for 1g. wheels?
Thanks!

Thanks, my son and I are building a car for his last Cub Scout race, last year we came in 1st overall in the pack, at the District we finished 3rd in the Webelos division, and 4th overall. Hopefully this year we can finish in the top 3 overall at the District, my son really wants one of those big trophies. I am also building a car I intend to send in for the first P.D.D.R. race. I have never ran a P.D.D.R. race and I am looking forward to the experience! dqracing

Glenn,
Thanks for the "Welcome." I can't wait to finish my new cars... they should smoke last years! ;D

Hey Guys,
Can someone explain why you want the wheels so close to the body. I thought the farther away the better, less chance of rubbing the body. Ideally wouldn't you want the wheels not to touch at all? Doesn't wider equal more stability? I need some help understanding why you would run your wheels with a 1/16-1/32 clearance. I don't doubt it's best giving the result A1 has had, I just need it explained to me.

If I could really explain why such close tolerances work better I might be able to sell as many "how-to" books as Doc Job. All I really know is "the proof is in the puddin'". If the wheels can move about TOO much it causes drag, too little and the friction eats you up. It's finding the "happy medium" for your particular car.

Steve is right on the money... every car and every builders build there cars different... you need to add just the wheel tolerances according to the way the car is set up... and it will depend on how and where you have the weight located on the car... so to tell you that 1/32 of an inch is the best... that could be wrong... I have found that differant tracks like the tolerances differant... The best track on my cars the 1/32 works best for me... Glenn

I totally agree with A-Line Performance & 2fast4u.
Let me add this........I used to use more spacing & then followed Glenn's lead to decrease it. I have found that wheels are less likely to experience "wobble"..........Steve's comment regarding friction reduction is right-on. With properly coned wheels & minimal friction from the inner hub........1/32 is a good set-up.

Mood, I'm in my office so I can't do your "experiment" so please give me a little hint. I also have a question: how do you guys tell if your alignment is on if you only have a1/16-1/32 clearence? Sorry to be so dense. I've used 1/8+ clearance and can see the movement of my wheels in or out, but with such a tight clearance I don't see how it's possible. Thanks for your patience and sharing your expertise. I really do want to understand this concept.

Thanks Pat,
I 'm starting to get the picture, but welcome any other explanations. Your idea about the test rolling is very helpful. I've been using Nyoil so it's hard to see the contact point. I use the Pro hub tool and file the axle head to limit the contact surfaces. Wish I had a test track to experiment with different spacings. Anybody else with more ideas, please chime in.

Thanks Mood,
Your input is much appreciated!!! Kinda sounds like it's alingment, alingment, alingment. I guess it's to the tuning table I go. Hadn't thought about the oil in winter time. Maybe I'll have to warm it up a bit or try some testing with graphite vs. oil. Any ideas on the best graphite? Any secrets on special blends? Thanks to all the guys here for their help.

Take another look at the info in "alignment and speed help" then under "test track". I don't think very many caught what a great tool a piece of melamine shelf can be. It is not the purchase of an expensive track but rather an inexpensive way to align cars prior to racing. When you really want to see how the car will work, one inch of slope in eight feet of flat surface can work wonders.

Last year my son and I found a very level area on our laminate floor in the living room, and adjusted the alignment until it tracked within 1" of the the line in the board. We centered the car on a board seam. I know it's not as sophisicated or as scientific as some methods, but, hey that car won my son two trophies!
