Sprung vs. UN-Sprung Clutch Twin Disc.?!?!?
Like the Title says......
Im in the market for a nice Twin Disc Clutch for my C5 Zo6 (Its a toss up between the McLeod RST/RXT and the Ls9R Katech clutch)
Only thing making me wanna spend double the cash on a Ls9 Clutch is that its a Sprung Disc type and by the Pics Neither the RST or the RXT from Mcleod appear to be Sprung.
I've seen a few post from guys saying that w a UN-Sprung Disc. they have had the input shaft splines start to twist from the hard engaugement, anyone got anymore info on this?
Also seeing that Twin Disc Clutchs dont last as long as Single Disc because they build up double the heat? This is a bummer to read as well, how long will they last w just general street wear and tear?
Thx!

The install instructions for one, heating the flywheel up to a
Certain temp before torquing.
I also know they don't work well for drag racing.
I know of one that was slipping with a couple thousand miles
Of street driving.

^Good to know!
This is the first I've herd a Negative about the Ls9 Clutch but havnt herd much on it at all to be honest w ya
and to have to heat up the flywheel before installing?! Is this just to immitate the temps its going to see after its warmed up as if it were in a car? Never had to do that w any flywheel

At the end of the day an LS9 kit is still a stock clutch. From experience, there are plenty of ZR1 guys that move away from these units to our Super-Twins. The idea that clutch life is inherently limited when using a twin-disc seems to be circulating in this forum and, though everyone is entitled to their own opinion, this isn't necessarily the case. It all comes down to usage. I have plenty of customers with thousands and thousands of miles on multi-disc clutches. At any rate, We offer 4 different Super-Twin options. I have provided a link to the kits below. Take a look and let me know if you have any further questions. Thanks!

From the 350Z world, un-sprung clutches don't damage the transmission but they are brutal on the street. I have a sprung OS Gieken twin in my Z and it's ok to drive on the street but the engagement is about as harsh as you would want in a daily driven car. Very sharp engagement even with the springs.

Twin Disc will have a light, stock pedal feel and more holding power = win, win!!

if you can find a quality (McLeod, Monster, SPEC) twin that fits your application, get sprung hub, even if just one disc is sprung.
For me, LT1, McLeod is the only offering for a twin and it has solid hubs. To my surprise street maners are very smooth.

Based on your claimed number you wouldn't have to have a Twin-Disc. Our Stage 3+ would easily handle this and provide great street friendly manners and easy effort. Of course our SST Super-Twin would be a great option too!
