Rewiring the race car.

The problem with using a terminal strip instead of a bus bar is, when all the terminals are "daisy chained" together, the first one in line from the power source has to carry all the current for the whole system as it passes it on down the line to be divided off at each individual terminal. That 8-32 screw in the terminal strip can't handle all your cars current. it would be much better to use a bus bar. They are available everywhere online and even Bass Pro Shop sells Ancor bus bars.

Also, I don't know why people bad mouth solderless butt splices, every airplane flying has them and they seem to do quite well.
