Even if you're not a fan of it just remember that twin disks aren't goign to be near as stiff on the pedal as a twin disk that holds the same torque. My os giken twin disk engages pretty harsh but i'd rather deal with harsh engagement knowing i won't ever be stranded. My leg is never tired because the pedal pressure is soft. Southbend will hold and still have some harsh engagement but the pedal pressure will be quite a bit more.

Well when you have a nice trailer and a nice truck and more than one person riding with you... Why not?
Besides as proven here you can break stuff at the track with street tires. I can pull good 60fts on street tires. Glad we brough the trailer or it would have taken an extra 8 hours instead of 4.

Thanks!
Well I like a stiff clutch 
Besides I don't have the cash for an os giken or any other twin for that matter. My jwt didn't strand me I'll give it that. A tough single such as southbend is exactly what I want, like the 260 which has a damn stiff 4 or 6 (cant remember, been a while) puck act.

Then southbend would be the way to go. I'm pretty sure Tom was using the full face stage 5 from southbend and he loved it. I can't remember exactly but in one of his posts (i think he lasted update) he said something about the full face working better for his high hp than the puck disk. Go check to make sure.

I opted for the Southbend Stage 5 FE full face also after seeing thom's car being able to hold high torque.
I had the ACT HD before but never pushed it to it's limit, it held fine with 457whp and 430 tq.

Ross's JWT actually held the power for his dyno pulls on that system and all his driving but it eventually failed because it was probably slipping a little bit every time he got on the gas.

Im for OS Giken as well. Jeff what model do you have by chance? On one my cars I'll be running a R3C setup. What do you recommend on the Z? Power wise/tq, not sure yet its up in the air.
Ross, glad my car is already torn apart. seems like you guys are breaking everything hahah starting with my roof on my car lol. Couple more weeks till I get out of Iraq WOOT. I think what you found on the Southbend will do fine for you as well.

That was on a vortech right? The torque on a s/c comes on a lot softer than the turbo setups so it doesn't stress the clutch near as much. Plus if you didn't hammer it much then it wouldn't have failed yet Ross's JWT actually held the power for his dyno pulls on that system and all his driving but it eventually failed because it was probably slipping a little bit every time he got on the gas.

Nice thread but I have to question the DIY when you clearly have your own shop and welder lift ect. Still the same nice build. It seems like your a mechanic or a son of a mechanic? When i think of DIY I think of not having a shop with a lift or a welder or a ****ing huge *** garage.

I just have an OS twin disk for a 2003. I'm not sure the model number. The only 2 choices i had were aluminum back plate or steel and i went with steel. Something like T2bd or whatever. It will hold way more than i can throw at it.

Ross has the work coming along on the cars.
ArmyMan its still DIY, just really luck to have those pieces to help the process. Instead of going everywhere and paying someone to do it. Ross get ready to make some room over there haha. We gonna be super busy when I get back.

My father and I both build cars, and we spent many years on our backs under a small carport with the cars on jack stands, but as much time as we spend in our shop now it was worth every penny.
As far as being a mechanic, I guess I can consider myself one. Not as a profession, but I have quite a few builds going on right now as well as smaller jobs here and there to pay for school.
Thanks for you comments on the build, I have put countless amounts of time and work into the project, and as any project, it's never finished.

Jeff- Thanks, I'll look into that model then. Any reason you chose steel over aluminum?

the 300zx had valvetrain noise.. sounds like its coming from the repaired cam. just going to have to pull it apart and see whats going on, but sounds just like a broken valvespring. That side was always a little noisy but you know how things show up at the track.
Hell, why don't we just talk on skype? lol
