Here's a discription of it, it cheaper than the Exedy which everybody likes, but haven't heard anybody using it.

HKS GD Clutch Pro Multi-Plate clutch kits $1,376

A key component delivering engine power to the drivetrain is the clutch. On highly tuned vehicles the stock clutch quickly becomes obsolete because it does not have the friction material nor pressure to hold and transfer the additional power.

Therefore a high performance clutch is needed to support and deliver all the engine power to the cars wheels. From using the T-002 and R33 DRAG GT-R to develop, test, and research the technology and dynamics of power transfer, HKS has created the HKS Twin and Triple Plate Clutch kits to surpass the demands of a high performance clutch. Twin Plate Clutch kits are designed for 700hp street use applications and the Triple Plate Clutches can handle over 1000HP, which are designed for drag racing applications.

The HKS multi-plate performance clutch kits are vehicle specific Pull-Type racing clutch applications designed for street-car use. The multiple plate design allows increased friction area and direct power transfer, thus offering greater horsepower and torque holding capacity and light clutch pedal pressure for easier clutch pedal management. The use of rivet-less clutch disks allow for better durability, increased friction area and direct torque transfer, while maintaining a friction material that is both wear and heat resistant. Each multi-plate clutch kit comes with a lightweight chrome-moly flywheel optimizes durability and high performance. The use of very durable and lightweight chrome-moly material with a steel tooth ring makes it possible to construct a thinner flywheel without sacrificing integrity. The concept behind a lightweight flywheel stems from the desire to enhance low-rpm throttle response on high RPM horsepower applications. With the lightened flywheel in the HKS Twin and Triple Plate Clutch kits, a quick rise in RPM can be attained from light throttle input for easier RPM matching when downshifting and to counter low torque at low RPM levels. Though the main focus of the HKS multi-plate clutch kits is on ultimate power transfer and engine response, a stable idle and smooth driveability is still maintained. Each HKS Twin and Triple Plate Clutch kit is a complete vehicle specific assembly that allows for a bolt-on installation. Some applications have an available slave cylinder rod that increases travel for enhanced pedal modulation.

How much power are you shooting for? seems like overkill to go with such an aggressive kit. most owners I know running multi plate clutch kits DO NOT like them. theyre like an on/off switch. no slipping to speak of, kinda like an unsprung disc but worse. If you can get away with a sprung disc and a high clamp capacity pressure plate then go with that.

Now if you have a drag only car dont worry about it.

I think i'll be around 585 hp at 27lbs of boost on a R85 turbo, from what i read from others using it. This wil be driven on the streets mostly. I didn't know that this clutch doesn't have a sprung disc. I didn't read that. I'm about to buy a clutch as soon as i'm done finguring out what will be the best for the price. This clutch sounds good, it sounds like it is made for the street.

Wow, this is totally contradictory to everyone I've ever talked to who uses a twin disk clutch.
The whole Idea with a twin disk is to create better clamping by increasing surface area instead of spring pressure .Too much spring pressure makes the pedal too stiff and severely reduces modulation, all while beating the crap out of your drivetrain to boot..Just increasing the surface area makes the clutch more driveline, and driver friendly.The "bad" thing about a twin plate is they tend to be noisy when you push in the clutch pedal .Make sure you get the right clutch, the GD pro has an unsprung hub while the Max is sprung. I have the Pro waiting to go in my car. BTW, that's a good price for that clutch, they're usually around 1500-1800.

Way overkill for your power and torque. Torque is what your basing your clutch purchase off of. An ACT 6puck with the extreme pressure plate is all you need. $600 will buy you what you need.

This is NOT TRUE my man. Do you know how a multi-disc clutch works? With a multi-disc clutch setup you can have 2-3-4-5 times the surface (friction) area (even with much smaller discs) with the same or less clamping force (pressure plate). Go drive a few multi-disc clutches and then drive an ACT 6puck unsprung hub with an extreme pressure plate and tell me which one is an "on/off switch".....

Will my Act S/S with a torque capt. of 408 be ok then? I've heard no a few times on here. I heard the 6 puck are like on and off switch, and you won't be able to slip the clutch, which is what i want to aviod. I have a light weight flywheel which you have to slip the clutch to get going. I guess i just will have to spend 1700 for the exedy twin disc.

I had the 6puck or years. You CAN slip it. Just take some time to get used to. And 400lbs torque is a cake walk for that clutch. If you drag race, ditch the light flywheel.

Thanks Ernie, Sounds good,I'll ditch the flywheel i do want to drag race it,but is this clutch alright for driving in stop and go traffic?
I should have around mid to high 500 hp so i think my torque will be high 400's
Also what clutch are you using now?

Im using an Exedy Triple Disc now, but I don't think you'll be making over 600lbs of torque, lol...
