There seems to be a great deal of interest in improving the performance of the old ProTrack brass chassis or the H&R. I began running these cars in the early 2000s with Cheetah (or Deathstar power for tracks like the Blue King). The cars were inexpensive and provided the young adults at the Prescott, Arizona High School club with the opportunity to set up the chassis, maintain the car, paint and detail the plastic model bodies. Most of the students were interested in NASCAR so we ran NASCAR bodies (although some of us built muscle and Trans Am cars). We raced these cars weekly for about 3 years. Over time we migrated to a set-up that included static pans, a soldered front axle tube and nail polish for the front wheels. Our conclusion after testing was that that the three simple modifications resulted in an improvement of about one second per lap. The how-to article entitled ProTrack Mods. that I wrote circa 2004 is re-printed in the files section of our Yahoo Group (

When we moved to Oregon, I joined a group of racers at a local club track, STR. One of the many classes we race is a ProTrack (old brass model/H&R NASCAR). As mentioned above, to get the best out of these chassis we run with static pans. Below are a few images of these cars.
