Re: Rear Differential...with all the recent talk
One or both wheels spinning depends on what rpm you start your burnout. If you start at a low rpm and gradually increase it will start with the passenger wheel and then lock up the driver's side and begin to spin as well. Both wheels have stayed locked thru the staging process and launch. If you don't do a burnout or at least spin the wheels until both start spinning, then at launch it's possible to spin only the one tire until the other locks up and also depends on the traction of the the track. If it's real good you with be at the 60' mark and not still spinning on the line. Unless your driving around with drag radials then it shouldn't matter, because by the time you guys put on the the intakes and pulleys you'll roast any street tire your going to put on that rim. If you are doing burnouts often, you might want to change tires from the passenger and driver side so your tires wear evenly.
