Well my output is based on the selfless sharing of others who have made these files available. I am really enjoying this as it really allows you to experiment and design.
Here is a picture of the chassis I built for this car. You can see the 3D printed front tires that have a groove in them to accept an O ring
The motor is from an ebay Chinese seller. They cost less the $2.00 and performance wise on my track there is no real advantage to spend more. These cars will match anything else I build, so I just use brand name motors for proxy racing. Stuff for my own use gets one of these 30K motors. As long as all the cars have the same motor, the racing they provide is fair and fun.

Other than the price being right is there a reason for using such high rpm motors? Do you run them at reduced voltage to make the cars manageable?

These motors turn high RPM with no load, but once loaded up they calm down. On my track they are easy to drive at 10 volts. I also am running a gear ratio of 4:1.
I have spent time sourcing out these cheap motors. Some have been unacceptable as they offer zero braking ,but I now have a mabachi source with part number I order, and these are suitable slot car motors. I can get 25 or 30 K . They may be high rpm motors, but they are very drivable as they have brakes.

Nice work....I like the suspension / rear end piece that you made as well. They actually add quite a bit to the cars, in my opinion.Come Race at The Trace!
