Here is an awesome setup guide for buggy and truggy. Very useful when trying to solve a handling problem.
Its published by Xray but the principles apply to any buggy of truggy.
And I 100% agree with backfire. Without the right tires, you are just chasing your tail. Tires are the first and most importenat piece of any track setup.
