And today I got to race a '99 Mustang GT with K&N filter, Flowmaster Exhaust, and a cold-air induction system. He got me, but not until the 1/4 was gone and only by like a car length then. (This was after he started out in front and so got the head start.) It was a good day.
I went to change the fluid in my differential and surprise! The bolts are on the far side of the axle. So I checked the fluid and painted the gas tank and axle gloss black. It looks alot better. Next step: K&N filter.
