Tilton Twin on the street, no thanks!

Oh man... Stay away from the ACT Xtreme. It's great at holding power but driving it around, especially with hills and in the city with NYC traffic I might add; is just annoying. For one the pedal is much harder than stock and if you don't adjust it correctly it'll kill your transmission (but thats with any clutch I suppose). Also, the clutch plate material is about if not exactly the same as the stock clutch so in essence it won't last any longer than the stock clutch.
Sometimes I hit myself for not getting the Exedy or Cusco Twin (haven't really found the difference between them as far as parts go and operational differences). The shop that I went to charged me $1700 for the ACT Extreme, street-lite flywheel and installation (yes, I over-paid
) When I could've payed a little more to get the Exedy Twin HD and right before the price raise. Yes! I feel so good about myself right now!
In-short I'm stupid and stay away from the ACT it's just not worth the price-tag, and def get the Exedy Twin HD or Cusco Twin Disk(doesn't really matter).

after running a quartermaster twin i'll never go back to a single disk again.
the disk material is also important...and while the metallic material holds more power...its not as forgiving.

Once this goes i'm contemplating running either the HD w/ a 6 puck sprung disc or switch to an x-treme w/ a street disc.
I too am debating an Exedy Twin but the price tag for those clutches is a bit much
I'll wait and see what happens when we get closer to 600HP on our dyno and more track passes at this current HP level.
So far verry happy w/ the ACT as many are likewise in the DSM world.

another factor is the clutch's ability to absorb shock from launching/high rpm shifts etc.
a twin/triple setup is going to put less shock through the driveline which ultimately makes our cars more reliable.

Does Mcleod make a street twin for the EVO? I've been really happy with their setup in a chevy LS1 t56 combo... Modulation is easy, the pedal feels stock, but when it hooks it grabs hard.

Dampened crank pulleys are for harmonics. Some would argue this point, but you don't build a clutch to absorb harmonics, that's not it's main function. Whereas it is the main function of a dampened crank pulley.

Are you saying a twin/triple has more "slop" in it, and isn't capable of transferring power as quickly as a single? The only way to transfer less shock to the driveline s to absorb some of the torque within the clutch, either by slippage or other, no? Why would a twin/triple put less shock on the driveline? I would think it's more of a function of the friction material used, and whether the hub(s) are sprung, but not a function of a single vs twin vs triple arrangement.

obviously this is all clutch dependent...but speaking in general terms...
first, twin and triple disk clutches have more surface area which allows them to hold more power with less relative clamping force compared to a heavy duty single disk clutch. anyone who has ever driven a dsm/evo with a heavy duty single can attest to the on/off nature of the clutch...and how unforgiving they are during launches or high rpm shifts.
the type of material and weight of the clutch disks both play a role as well. semi-metallic disks vs organic disks...etc...
its interesting to see the evo community (who generally has more money) run more expensive clutches and the dsm community (with less money usually) still run the tried and true act 2600 etc...and there is a reason for it. new technology simply makes our cars shift better and last longer.

I am close to 2yrs daily driving my tilton everyday as well. I am very used to it now. The only issue is that I am the only one that can street my car. Everyone else that does has trouble. Its not an easy clutch to drive at all and I have gotten to the point lots where I was gonna say screw it and go exedy tripple. I love my clutch now. You will get used to it believe me. And yes there are tons of hills here in Tucson....
good luck!
