Well, the car IS broke again that's the issue. Didn't go through all the details in this thread, just trying to get opinions on couplers.
I have been through 2 torque tubes in the past 7.5 years I've had my car. Both due to failed OEM couplers and relatively low power. They were both pre-01 10mm units however. I wanted a 12mm unit when the first one went, but couldn't get one at the time. One shredded the front coupler and jacked up the tube. Could not be reused. The 2nd one didn't cause the tube to fail, but jacked the input shaft. So it was repaired ("thought" so, runout was out of spec unfortunately), so now I'm pulling that tube back out now due to a nasty vibration during first 100 miles since reinstall. It's the input shaft. Now it's getting new stuff, I'm tired of screwing with it. I just ordered the DSS poly couplers for my new 12mm tube. I'm contemplating ordering the 3" shaft as well, but prolly won't go that far.
This is the first 12mm tube assy that I have had (absolutely perfect low mileage unit) and I'm paranoid about screwing this one up from another coupler issue.

Are you using a carbon fiber shaft?

You will not have no problems with the RPM stuff here at all. My two stock couplers totally was shot from the rollers at only 600 rwhp. I mean shot. Now with almost 1,k rwhp on the rollers they still look like new.. Robert
