Twin Disc Clutch Life
I'm looking to purchase a twin disc clutch for a 500 WHP LS3 build.
I know it's overkill in terms of torque capacity, but I would prefer the lower pedal pressure as I think it will be easier on the clutch hydraulics, as well as the thrust bearing on the engine.
The vehicle will be an early 90's 240SX @ about 2700 lbs.
I'm mainly looking for a McLeod RST/RXT, or an ACT Twin Disc. Leaning more towards an organic based disc since I don't plan on heading to the drag strip all that often.
Vehicle will be used for auto-x, daily driving, and tomfoolery.
What kind of life have you guys gotten out of your clutches?

because you have such a light car you can get away with much less clutch. but if you want a sweet clutch look at the RPS carbon. you can just get the base level twin. and it would last you a while.
I love the carbon clutch's cause of the amount of heat they can take and still drive stock.

Save the money and throw a Monster clutch in there. I'm running a Monster Stage 2 (full face disc) with a lightweight 18lb flywheel, and I love it. Smooth engagement, but firm hold when needed.

There is not that much money saving with the Monster setup.
Based on the website, it's around $800 shipped with the lightweight flywheel.
Besides, pedal pressure has to increase with it over a twin. That is something I want to avoid.

I agree that a single-disc will be a better option. In fact, we build a great number of kits for folks running LS powered 240's and I would be happy to assist you with any questions and/or recommendations. If it were mine I would run the SPEC Stage 3. We also offer both steel and aluminum flywheels and even an aluminum-plate option that will further reduce mass and provide you with a rebuildable plate assembly. Either way let me kow if you have any further questions. Thanks!

What advantage does a Spec single disc have over a twin?
I would think that a twin's clutch life would also be much longer than a single.
Even thought it costs more initially, even rebuilds would be the same if not cheaper than a new single.

Cost and weight would be the most obvious differences. Rotational mass will slow down the speed at which you are able to shift. The less weight spinning on the shaft the better. Especially if the single is more than able to handle your torque output. Additionally, clutch life is not inherently greater for a twin-disc. This is relative to the kits ability to handle the torque produced and the nature of your driving style. Also, with the Aluminum-plate option you have a rebuildable single-disc option and rebuilds will be less than those associated with the Super-Twin. It just comes down to what you want and what you need.
