Uhp! broke more stuff.
 
so I was illegally racing a ferrari when oh noes!

but seriously, floored it coming up mccaren and spun the clutch at the top of third. guess im making too much power finally.

anyone have any opinions on sti after market clutches?

im thinking ill rock the twin carbon cusco, or just the twin plate. they seem to be cheapest and best way to go.

I like the ACT unsprung 6 puck that Dean put in his Sti. I'm pretty sure it's what I'll be doing soon. Dean let me drive his and I like the feel, it's still moderatley streetable but holds like hell.

dayofpain 2007-11-24 05:08 PM

which flywheel did he decide to go with ?

pro or streetlite?

dayofpain 2007-11-24 05:13 PM

i wonder how much el cheapo got his installed for...

MattR 2007-11-24 05:21 PM

I don't know which flywheel he used, does it say in his thread? I think GST did his install, so it must have been a good deal on it.

Kevin M 2007-11-24 05:28 PM

I would espect he went with the Streetlite, but I can't say for sure.

MPREZIV 2007-11-24 05:29 PM

Pretty sure Dean's got the streetlight.

dayofpain 2007-11-24 05:37 PM

that would be odd IMO to go streetlight and 6 puck...

ill call gst on monday see what they can offer for install.

MPREZIV 2007-11-24 05:41 PM

Actually, it specifically says so in Dean's thread... "streetlight". It's the same setup I put in Ryan T's car a short while afterwards.

REALLY nice feel to it on high power cars, without being too much of a PITA to drive.

dayofpain 2007-11-24 05:43 PM

wierd, wonder why you wouldnt spring for the extra 20 bucks and drop like 4 more rotating pounds.

MPREZIV 2007-11-24 05:46 PM

Most of the time, cars that are regularly driven on the street will be a HUGE pain with too light of a flywheel... The lack of inertia causes it to be a bitch in stop and go traffic. The seriously light flywheels are typically left alone by guys that want to, or have to drive their cars on the street at all.

dayofpain 2007-11-24 05:51 PM

easily said for an unsprung clutch as well.

im well aware of the disadvantages of both. if 6 puck... whynot super light ? would actually make things easier on the clutch. more rotational weight would make the unsprung clutch feel worse but if the flywheel is light then its less noticeable, buy actually a big difference.

Trust me man, we were all a bit dumbfounded by this as well, but it's REALLY smooth and easy to drive for being a 6 puck, unsprung clutch. There is just some kind of a "zen" little spot, that is found in between the exact weight of the street-light flywheel, and the engagement of the 6 puck clutch. Other combinations of ACT's clutches/flywheels just don't have the reputation for holding as much torque, or being as smooth as this *exact* combination.

My favorite street clutch combo on a 6sp by far, holds well with plenty of grab but able to be slipped when needs be.

We run the unsprung 6 puck in the race cars but with the Prolite flywheel, not sure I would want to drive that on 880 freeway at 8am Monday but makes for a great race setup.

how many hours you guys charge for the clutch / flywheel install ? or do you have some package deal type thing.

Dean 2007-11-24 08:00 PM

ACT 6 Puck w/Streetlight FTW. It will launch like nobody's business at autocross and is still very streetable.

It is already a bit weird on up shifts having to almost sort of rev match. The ultralight would just spin down too fast and not be fun on the street IMHO.

sperry 2007-11-24 11:54 PM

I've got the 4 puck ACT and the Prolight. I wouldn't want to drive it on the street regularly, but it's not impossible.

Let me put it this way, if "10" is the stock clutch's driveability, and "1" is un-streetable, I'd give the 4 puck and prolight a 3. The exceedy hyper-single I had before, I'd give a 4, maybe a 5. From what people tell me, the 6 puck/streetlight is probably a 6 or 7.

I had a Exedy Twin HD in my evo. On scotts scale I would give it about a 7-8 but I don't know if they make them for the sti? The evo guys use them to up around 450-500 whp. My kit came with a flywheel.

We charge based off 5.5 hours and round down :D
