I have been bracket racing for over twenty five years and did the try to go faster/ lower e.t.thing. When they moved Pro to 9:00 as the fastest my car ran mid 10s I got out. About 8 years ago I put a mechanical throttle stop on along with DOT front tires and Q.T.P.s on the rear I slowed the car down to run 11.50 for Street Eliminator and 11.50 index racing and am having a blast resulting in more round and eliminator wins than ever before. Index racing is fun here in the Northeast division they run index classes at some points/ open races and we got to compete at a National meet running 11.5o index which was really a ball.
