I think I have a basic understanding of what effects the reduction of reciprocating mass has. But, I don't know what the weight of our stock driveshaft is, and what a CF one weighs. I don't even know if one is readily available or if it would have to be custom made.
I know from previous posts that Hellasboy was looking into it.
Also, I wanted to know if anyone has actually done it and could tell me a bit more on the real world benefits. But obviously nobody here has one on their Lex, so maybe the benefits don't really justify the cost.

Wow, it's been a long time since I considered doing that mod. I'll check around to see if I can find a junked SC400 and see how much the driveshaft will cost...
I contacted ACPT about CF drive shafts for our cars, I forgot exactly how much weight we would save (it's been a long time) but Supras saved around 40 lbs (18kg).
They would need a stock driveshaft to model the CF version and it would take 1-2 weeks. I believe Clint has one on his turboed SC300 but I haven't heard of anyone using one with an automatic transmission... yet.
As for what to expect, I *think* that we can get more horsepower to our rear wheels (considering how much our transmissions suck up) and that acpt claims higher rpm (which we can't take advantage of unless someone can modify the ecu to redline at ~6900 RPM).

I wouldn't waste your money on one. If you want to save weight, look at a cheaper Aluminum version, it will be plenty strong. As far as ACPT saving 40lbs, lol. 
Thanks, I haven't laughed like that in a while. The ACPT CFDS barely saves a few pounds due to the massive metal part of the slip yoke they have to use. Sorry guys, I'd look elsewhere to free up HP.
