1992 Pontiac Firebird (stock)
- 5.0L V8 TBI / Automatic Trans / Every option, excluding leather
- Killer car audio system:

• Aiwa CDC-MP3 head unit
• Rockford Fosgate 360a2 amp
• pair of 12" MTX Thunder 5000s in a custom box
• Pioneer 3-way 6x9s, soon to add more more more!

 

For one, this is a power adder board.

Ignoring any loss in power for imbalances the benefits of an al driveshaft are minimal. Even though the driveshaft will weigh less statically, the moment of inertia will be very similar to a steel unit because al driveshafts usually have larger diameters. So, is the performance gain of 15 pounds (max) static worth a few hundred?

Now driveshaft imbalance is another issue but I doubt your car has issues with that yet.
