OK all of you that witnessed my shocking 1/4 mile run where i left half my clutch on the start line will understand that i am now trying to get information about what clutch to put in my skyline as i dont think mine has much life left now.
I would really like to get a clutch and flywheel package so i know everything in there is brand new.
I want a clutch that will handle 650 bhp no problem so it doesn not need replacing in the future and can also cope with the odd 1/4 mile run and trackday.
I have heard the nismo coppermixes are a good buy and the feel is also near that of a stock clutch as i use my car for road driving aswell this is quite important as i dont really want a on or off type clutch for when im driving in town etc.
What do you guys suggest?
Cheers.

OSG always used to have the best reputation for gentleness and useability.

My OS Giken T21xxx (can't remember the full numbers) was a bit of a bugger as we discussed Ian - but it really did hold the power.

The recommendation from Abbey was the HKS GD MAX for my application as it's light even though it's a twin.

you'd need a triple plate o.s giken for 650bhp really and on track it would be a dog.... not ideal.
If your willing to spend a few bob go for an rps carbon carbon will cost around

I used the HKS Pro triple plate and it was effectively a switch,

A very very light switch (pun is optional :D ) that whilst you could drive it around ok once used to it, it was still a slight lottery on pulling out of junctions in a hurry !!!

Mark rates the carbon/carbon clutches quite highly I believe.

The ORC (Ogura Racing Clutch) twin plates are pretty cheap if you can put up with a bit of rattle from the plates.

How much is pretty cheap Ben and where would you suggest looking?

I could also be interested - sounds like a club gearbox out and clutch change afternoon - count me in.

Change in an afternoon is a bit optimistic Ben!
I dont care about any rattle from the plates.
Alex i think you are way optimistic on my budget and the power of my Skyline :wink:
I am looking for a clutch that will handle roughly 600BHP all day long and will handle a bit of abuse on the track and odd 1/4 mile run but needs to be fairly user friendly as the car is used on the road aswell.
I cant seem to find any info on the HKS GD max Ben?

Mate you didn't look hard enough - typed in GDmax into Google - and hey presto - loads. Tisk Tisk

The HKS GD Clutch Max is the latest evolution of the HKS multi-plate clutch series. The GD Clutch Max features the same multi-plate design and lightweight flywheel of the GD Clutch Pro, but also features a sprung hub (on most applications) and special engagement springs (patent pending). The sprung hub absorbs engine torque which helps increase the life of the transmission, and aids in decreasing gear noise. The engagement springs are placed between two pressure plates and the center plate. --- They force the clutch plates to engage one at a time. Doing so makes it easier to slip the clutch, improving street drivability and clutch control.

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.
