I was told a story about Kip Martin (RIP) and his Super Stock Mustang.
Kip ran an Aluminum drive shaft which broke at a race.
I was told he found a steel replacement and his car slowed down a few 10th's and MPH.
As soon as he replaced the steel unit with an Aluminum one, he gained back his ET and MPH.

Also, as I understand, Stephen Johnson replaced his steel unit with Aluminum and also picked up ET and MPH on his Fairline.
