Any experience with lightened TH400 internals?

[TTA850]

Been looking at some websites and see they offer lightened oem parts and alum replacement parts, anybody using this stuff? Been thinking of ways to get more power to the ground and was thinking this might help but I need it reliable on the street aswell as the track.

lighter internals and rollerized parts will produce a better et.especially the aluminum direct clutch drum.
