OS Giken twin plate unsprung hub clutches are streetable. It's the user that needs to learn how to drive it... not launch it. With the twin plate it's easy to launch. Rev to whatever RPM and dump the clutch. The transmission can handle the torque shock. There is no such thing as clutch slipping a twin plate...why would you need to?



For reference I have driven an OS Giken twin plate unsprung clutch for over 4 years in the FD...probably the same type as you (b type steel clutch cover ...should be TS2B part number) and have only had a problem driving it when breaking in the plates. THAT'S IT. My grandmother could drive my former FD. I know that Dragon, FDOkinawa, igy and two other friends of mine who all run/used to run the b type OS Giken twin plate clutch have said it's very streetable. Are you SURE your plates are broken in?

definatly a lack of ttraction...between the 4.10s(3.42 in most m6 ls1 cars) in the fd rear(i thikn its 4.10) and the couple of hundred pounds that it weighs less than my car and I can break them loose in 1st and 2nd at pretty much any rpm...and if i shift out of 2nd inot third near redline....it'll spin third...so....not an excuse for him, but I can see traction being a huge issue.

I know. Loss of traction seems reasonable enough. I think in the same stroke however, and according to some knowledgable/experienced rotary-owners who had seen/riden/driven my car before I bought it, I'm workin' with a pretty nice FD myself. I couldn't ask for more.



Regarding the clutch. Essentially, of course it IS streetable, my driving it as a DD proves that much. It just took some getting used to. I can drive it fine now, and I think I've figured out that yeah, basically, to launch it, it needs to be revved to about 5K and just dropped. Any lower than that and it bogs, and any type of "slipping" doesn't help either. The idea of shakin' up the stock diff and suspension with 117k miles on it doesn't put much of a smile on my face, however.



What are your suggetion(s) for launching her right?

Dumping at 5500rpm IMO is a good place to start. Then vary it up and down until you lose or on the hand gain traction.

There's your answer right there. If you start to wheel hop...rev higher. 1ST thing is to get an aftermarket diff. Stock diff can take the torque of a V8...just not the torque shock. Was it Brian Stinson that used a V8 on his rx7/LS1 swap? He would run 10's and launch at 3000 rpms. When he went to 5000 rpms he blew the diff.



Also upgrade to aftermarket toe links/trailing arms. After that...well it's all driver.

nice race. sounds like fun. what is the guys screen name with that ls1 FD?

Something like FedUpFD3S or something, on RX7club.com that is

To bad you didn't launch.**** V8 rx7's.

Not to hijack but a buddy of mine is putting a 351 in his FC in the next few months, the motor is being modified right now, longer duration cams, etc. So when thats done its going to be my T2 w/ light mods vs. his little v8 monster......



I will just get some video...

I am a FC guys, so excuse the ignorance, but fuel cut at 6,700rpms?
