That said, if you're trying to strip weight off the car, I see no season why you wouldn't jump on this for less than $400. It would be silly to do a lightweight flywheel, upgraded clutch, and not do the driveshaft since you're down there anyway.

orr people who know what the benefit is don't see the benefit of sinking $400 into something that literally gives little to no realizable performance gain (read: the driveshaft upgrade can be seen as a structural integrity upgrade moreso than a performance one), and put that money into something that will yield far more benefit, such as brake upgrades or tune.
Some people love to throw money at things, others like to optimize their cost/benefit. It's no right or wrong answer, just one that 'works' given the goals and environment the system is in.
"Down there anyway" the driveshaft is actually pretty far away from the clutch, FW (other side of tranny

) and literally takes 10 minutes to take out..
