Anthony,
I've thought about breaking my cars in that way, but never got around to it.
It should work.

Now that's what I call getting in shape for the big race.
I once tied a car to a belt sander and it actually got some of the high spots off of the wheels.

That one should go in the "It worked for me!" topic.

That one should go in the "It worked for me!" topic. well I ended up with the fastest time of the day! At the end of the racing I asked who had the fastest time ever on that track....he only had records for 2007...My car is the fastest so far this year!!!.....the weird thing is I built 3 cars to enter and pretty much did the same thing for each car.....but only one car was really fast....this car building is driving me crazy....I wish I can find more races to enter here in NJ this year... tony

Have you ever thought about joining others in the monthly proxy racing?

Tony,
I think it's just human nature to focus on the process, rather than the physical result. I have lots of conversations with people, and even on this board, a lot of threads start out: "I built my car this way...".
A car is fast because of its own physical attributes, not how you built it. If a process is variable, the speed of the cars will be variable. If the process is very robust with little variability, then all the cars will consistent (but not necessarily fast)
If you don't follow me yet, here is a real example: My work buddy lost the derby this year by a lot. He couldn't figure out why, because he "built it the same way as last year." (Last year, he won.) He drills the axle holes using a drill press.
Well, considering all the variables that influence the parallelism of four small holes drilled into a wood block (not uniform) whose sides are not parallel, no two cars will ever be the same, even though they were built using the same process. This is because the results of the process are never the same; the result depends on the wood itself (among other factors).
Also consider this scenario: one builder sands the wheel treads by hand to make the wheels round. Another uses a CNC lathe. Using the "process" logic, all cars built by one builder should all run at the same speed because all the wheels were sanded the same way. But intuitively, you know that none of the hand sanded wheel are the same, nor are they round, or concentric, or... because the physical result of the process is different every time. The car built with the lathed wheels are faster and more consistent because the result of the process is consistent and round and smooth and cylindrical and... well, you get the idea.
Use building processes that result in the same physical attribute every time, measure your cars the best you can to determine differences and do it a lot! Build lots and lots of cars and measure, measure, measure and test, test test.
Oh, and have fun!!!

That is driving all of us crazy. It seems like with experience the times get faster, but why one car runs well and another doesn't run as well, keeps us all awake at night. If you want to do more racing, you should try the proxy racing. You can learn a lot, and have a ball doing it. Come join the fun. Phil

The problem is, I would complete a car and then learn or think about something new I could have done and it's back to the drawing board. The funny thing is the very 1st car I built was a fast stable car that finished 2nd out of 56 entries a few years ago... maybe we just try too hard and it's time to get back to basics..LOL
