Help needed with naming a Commodore 64 game

[chaparral]

I can't remember the name of a game I used to spend many many hours playing on my Commodore 64 years ago...
I was hoping someone on here may remember what the name was...

All I can remember is that it was a racing game and it was only available on a 5.25" flopping disk



(if I remember right you could make your own tracks,but am not 100% sure on this)

Think i just found it..

Racing Destruction Set

Looks like it was released on cassette as well..

Racing Destruction Set was supplied on either floppy disk or two double-sided cassette tapes. Side 1 of the cassette had the game files and sides 2, 3, and 4 had track files. The cassette conversion of this game was done by Ariolasoft.

4 sides ..no thanks
