You won't see any gains from an aluminum driveshaft.
The only reason people get them mainly is due to vibrations encountered after putting new gears in because the driveshaft will be spinning a lot faster, causing it (with the weight) to be slightly out of balance or fucks up the U-joints. OR they are making some sick power. Even still you rarely hear of it being a priority.
I have never heard of anyone putting them in in attempt to gain power or simply go faster. For the 1hp you might see, is $200+ dollars worth it? No.
I don't know what kind of ricer shit you see that makes you think an aluminum driveshaft will make you go faster.
I think you need to sober up and not let your fingers talk until the morning.
That and something about fuck her, more fish in the sea,,,yada yada. it was broken off for a reason.
