Need advice for slowing my car down consistently.

I have found that it just as hard to slow a car down as it it to make it faster.

When to Firebird raceways in Idaho. Wanted to stay in sportsmen but the cut off was 14.0 At RMR my best was 14.14 but usually in the 14.20.

Firebird was lower altituted so i make up a spacer rod for my throttle so that i could only get half throttle, drop 5* timing and short shifted (800 rpm less)

What did i do......ran my first 13 sec run! (13.95)

As other have said, try and find a sponsor to help you thru, and run Pro.
