What was the title of the anime where kids raced small toy cars?

I remember when I was younger, my brother would watch this anime and he'd buy little toy race cars that had modifiable wheels, motor, body, axel.. everything. The cars were size of a person's palm... Teams of five were in the anime... please help.



Thanks.What was the title of the anime where kids raced small toy cars?
