If you're gonna race, take it to the track.... safety first... always. Everyone knows somebody killed in a car accident and it's never right, especially if it can be avoided.
Buth there are a few last minute things you can do... at the track of course.
-Take out your spare tire, and jack, etc (people always forget that one)
-Take out the passenger seat
-oil change with synthetic oil (mobil1)
-run through some non-solvent based fuel injector cleaner (Redline SL1)
-replace your fuel filter if you haven't
-Throw some "Water Wetter" in your radiator
-Clean your throttle-body
-High flow filter/ Intake
-Clean the engine bay, it'll run cooler
-Make sure your tranny is in good shape, possiblty flush it
-Properly inflate the tires
-Lighter battery or relocate it (post on this not that long ago)
-Loose weight wherever possible
I AM NOT PROMOTING STREET RACING PLEASE GO TO THE TRACK.
good luck and be safe
