I've heard that it frees up power..I'm looking at doing this just so I can run my car harder without the wear, but is it actually good for a measureable gain in power? That would be a plus..

eh, doesn't really free up much power. it's just lighter. might be easier to spin since it's lighter, but it's not really gonna be noticable power difference

Well, if it takes less energy to spin, that would make the set-up slightly more eficient, sending a few more ponies to the ground.

dosnt really free up power, but allows the engine to wind up faster, reaching peak power faster allows faster acceleration, pretty much the ide there.

i also heard that the stock driveshaft for my third gen is only good up to 90mph before it becomes unstable, even thought ive buried the needle a few times with no noticeable problems during or afterwards.

thats a load a crap. i've gone 130+ in a camaro many times, no vibration or anything still felt stable

So if it spins up faster it will make te car faster, there ya go.

yeah ive had the RS up to 115 and the IROC up to 105 neither had a vibration from the driveshaft.
