one piece driveshaft??

[Petros AE86]

whats your opinion? one piece driveshaft or with driveshaft carrier bearing?
its daily driver but more than 180rwhp

I have used both and I'm now using a two piece with a centre bearing.
Vibration from the one piece shaft was my issue, it was professionally
built by a very reputable company too.
Difficult because of the pinion angle I believe.

I've been running a 1-piece on mine... at 209rwhp.

and whats the hp looses of both???

You would have more hp losses on an original one, but the most important thing about the one-piece design is that it is lighter and with less rotational inertia, which is a good thing.... Dunno if you can live with the vibration though!

Just use stock unless you are forced to go custom driveshaft. All the theoretical babble ends up amounting to nothing much noticeable, besides the vibrations when the pinion angle is out.
Its not light enough to make any difference (and the weight is right where you want it). The rotational inertia is identical, certainly compared to the flywheel. Lots of other places where you can spend the money.

If you do buy one, adjustable 4 links are a must, as is andrews article about setting the angles.

Just another opinion to add to the bunch.
