That's the bottom line or Alltime will put a big rookie X on the back of your car, just like at the races.

But, but why? you ask?
It's as much about driving as it is about the car. I'll let professional race car driver and National Solo champion Randy Pobst explain Why Understeer is Your Friend

On the car side:
If you think Frankenduster is speaking from a unique point of view, Steve will tell you from personal experience on that very track. I can tell you from personal experience on roadways (I was younger once). Mike Ritz can tell you from personal experience racing a '66. The list goes on... With the a-bodies, start with no rear bar for high speed. Then as decide if adding a little bar (soft) is wanted.
