Message	All things being equal. However, aluminum driveshafts are made of thicker material (which is still lighter than steel) to make up for the loss in strength. Other notes about steel vs. aluminum -Aluminum has no endurance limit, so over time it will slowly become weaker and weaker until it ultimately breaks. -Steel has an endurance limit (usually estimated 0.5*UTS) which means it will fatigue to a point then remain at that strength (designed into the shaft) The one thing you don't know is the designed life span of the aluminum shaft. Now that being said, I had a 1 piece aluminum shaft that I installed with my lightweight clutch/flywheel kit and I felt like the car was much more responsive, and a lot more fun to drive. I will be going with another 1 piece aluminum shaft from Z1 for this project car as well.
