Welcome to the Bando world. I hope you find Bandos as rewarding as my son and I have!
Here is one opinion:
These cars are not perferct, but they do allow our young drivers to compete and learn. I think the cars do not have front suspension or brakes to keep the cost down, and also to keep the speeds down. The cars have only 150 total parts, keeping tem simple makes them more attractive to racing newcomers.
These kids today are driving these cars far faster than they were originally designed for. The skill level continues to rise. If they had suspension and brakes it would further widen the seed gap between the new drivers and experienced drivers , compromising safety.
