steel or aluminum driveshaft?

[Jim Kaekel]

I really think it depends on the application. I swapped a steel for an aluminum driveshaft at the track for a back-to-back comparison and gained absolutely nothing. The added bummer was that they were checking driveshafts at that very race. They wound up banning them at the end of that year in Stock Eliminator, unless they were OEM for the particular car.
