Review of the ATS Twin Disc Clutch--Test Drive Impressions
I had the opportunity to drive a Stillen SC 350Z with the ATS twin disc carbon clutch and flywheel that a bunch of are planning to install with our built motors.
At idle, there is a definate increase in noise...but not obnoxious in my opinion. The noise is just a tad louder than a typical Nismo clutch/flywheel combo.
The clutch engagement and pressure is just like stock. You do have to give it some revs and "slowly" release the clutch to get a nice clean start. But with an hour of practice, you will be driving it like stock. The owner of the car gave me a ride first, and based on how he handled the clutch, I couldnt tell the difference in terms of stop/starting feel vs. stock.
With the lightened flywheel, the engine revs like a motorcycle. Super fast and light.
So overall, I really like the setup. It can support around 750/fl/lbs and should be the last clutch that any of us ever buy. The thing is virtually indestructable, and gets better as you heat up the carbon discs.
Just wanted to share my findings. Price is roughly $2000 if anyone was wondering.

A lot of people like the twin disc becuase they have smooth engagement, can hold massive trq, and they never wear out. Figure that a good clutch and flywheel are around $900. There are those that want to spend $2000 and have somethign that never needs replacement. That is one of the biggest benfits I see. I got a quote for a clutch job on my 350z, and the shop wanted $500-$600 in labor.

Sharif, just wondering because this was brought up in another thread...how long will this clutch/flywheel last? Forever? Even under race conditions say every Friday and hard driving say...2 or 3 days out of the week, the rest would be normal driving?

Sharif, wait until you drive the 1350 pressure plate. the pedal feel is not like stock, but not so hard that it is annoying. Much firmer with all the benefits of the clutch you drove. You're gonna love it!

I have the 1100KG pressure plate. The heavier plat is available, but the guy at ATS told me its pretty nutty, and he only recommended it for racing.
Nis...twind disc carbon clutches will last almost a life-time...even if periodically raced. If this was a race only car, I would actually recommend the triple disc with heavier pressure plate.
If you do a couple of drag events a week, and then normal driving during the rest of the week, this clutch should outlast the motor. To me, that is the biggest benifit of going with this type of clutch. Twin or triple disc carbon are virtually unbreakable, but they last an incredibly long time.

What's the weight of the flywheel that comes with it?
It'll probably be quite a while before I go FI, but I have considered getting this clutch when I finally need a replacement. I would be ready for FI in the future and get the benefits of a lighter flywheel.
There is a single disc option on this clutch, correct? Can the second disc be added when it comes time for FI? And is this a simple add-on or does the original disc need resurfacing?
Thanks,
Jeff

Not sure of the flywheel weight, but its less than 20lbs. Becuase the entire assembly with flywheel, disc, pressure plate, etc...is just under 26lbs.
There is a single disc option, but you cannot add future discs later. The single disc option is around $1500 IIRC. There is also the triple disc for around $2500.
Its a bolt on affair, and becuase you are replacing the flywheel as well, there is no resurfacing required.

someone on here said the triple disc would be easier to drive than the twin disc. If that's true, i wonder if it'd be worth it at all?

My car is STILL in the shop, but I plan to do a review of the ATS twin 1350kg plate setup as soon as i get my foot in it. So here is a bump for my GB for the ATS clutch!
