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?

If you also have any recommendations (assuming you have a similar vehicle), that would also be very helpful.

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.

Those RPS units may be good, but too much for my wallet.

I was leaning more towards the McLeod units for their lower costs.

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.

Something that can be rebuilt would also save me a bunch of money down the line.

I run an Exedy twin and its awesome. GT04SD or GT01SD. They are technically exactly the same clutch.

With it being a Stage 2, the pedal pressure is hardly noticeable unless you want a REALLY easy pedal like stock?

I would like a unit that would also not cost too much when a rebuild is needed.

The Exedy is really expensive to rebuild.

at your power its fine i would do a single but when you start burning up disk at higher power the twin carbons are a deal.

go to tickperformance.com.....they have a full clutch kit deal that is incredble........you get all new hydraulics, monster clutch of choice, and if you went with a standard steel flywheel you are at 1195...best way to go for sure....

check out the centerforce DYAD twin disc. I love mine and i have 850rwhp and it has taken me 188.5mph in the standing mile without a HINT of slippage. Feels like a stock clutch too

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.

SPEC-01

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.

what kind of clutch fluid do you use?
