cruzinquick i think what he is asking is how to do the burnout to clean the dr's. for me i back into the water box to wet the tires then ease out. car in 1st esp off brake the car and gas it. doesnt take much to brake the wheels loose. get them good and warm, maybe a 3 to 5 sec burnout. release the brakes under power and shoot forward easing off the gas. now line up for the lights. avoid wheel hop at all costs! my goodyear dr's were so sticky i did wheel hop in may and thats all it took to hurt my diff.
BE WARNED!! waterbox burnouts with dr's can have adverse affects on the rear diff!!! racing breaks parts. knowing that enjoy the track, i love going down the 1/4. but it comes with a price.
