BMR Carbon Fiber Driveshaft Wondering what you guys think of their carbon fiber driveshafts. I seached but didn't see any opinions on them. I noticed they have a 3.25" one for $599. It seems like that is a little cheaper than others like the ACPT that cost around $800. Is the quality the same? I'd like to go as light as possible, but still have some strength.

If your looking for every ounch of weight, get it . One thing Ive heard is if the carbon fiber breaks it will shatter apart so its safer.

I have a carbon fiber driveshaft, but it was made by PST. In then end, it was the same weight as my stock aluminum shaft, but much, much beefier (3.75" diameter, 1350 u-joints, powerglide slip yoke, etc).
If you are after weight savings here, don't bother. The moment of inertia of a driveshaft in operation is just too small (all the mass is close to the axis of rotation). Carbon fiber damps vibrations very well, which is why I got it.
