I just got my ACT 6 Puck Sprung with Prolite flywheel installed. I will be doing a first impressions write up of it this evening, just follow the link in my sig.

Drove the car today (got it back, sniff, sniff). The clutch is obviously harder than stock, but not obnoxious at all.

The engagement is fast, but I can tell right away its not as harsh as the 6 puck varieties. You can slip it a bit.Its not the type of as soon as there's some little contact BOOM, is completely engaged. I know this might change after break in so I will updated when I complete it.

There is a little bit of clutch noise when idling in neutral, but it's very minor compared to most other aftermarket clutches. This clutch is 100% parallel parking friendly.

Please contact us, if you'd like any additional information.

I'm not FI but my act street clutch and prolite flywheel is perfectly street able. It idles just fine. There are some funny noises at idle when the ac kicks on but it's not a big deal. What kind of setups are you guys running where you're generating 300+ ft-lb of torque? I think if I'm lucky I'll get 220 ft-lb once I'm fully built out (full na engine).

You should probably go with a full face clutch if you can't take the 6 puck sprung.

ACT streetlight flywheel and its a sprung disc. When I drive in the city I get chatter at red lights, moderate vibration under "cruising" conditions and rough engagement. But at The Dragon I felt like the clutch was performing well and holding up to the constant shifting. I will look for ACT to release a street able disc comparable to the fx300/fx350. My friend has a +500whp S2k with the FX350. His car feels better and has none of the noise mine has.

Ok getting some data now.

I am going to give the ACT streetlite street disc kit a go. I have it in stock and have faith it will give me good holding power with good feel. We are probably going to be making a good bit north of the 270wtq rating.

I have driven a couple of clutch setups on my car (avo turbo). But I was chasing an oem feel and nvh so settled for an organic disc with uprated oem style pressure plate and a chromoly flywheel.

ACS Xtreme range. http://www.xtremeclutch.com.au/en/ Paul @ AVO should be able to supply it stateside I think.

Spent some time yesterday breaking in the FX300//350. I need to drive a 6 puck clutch to know the real difference, but this clutch seems pretty easy to drive. This might sound stupid, but I find it easier to smooth shift in this clutch then the stock one. Maybe all of this will change when its completely broken in, but that's how it is driving so far.

FX300/350 it is! Unless something else comes out between now and june/july.
