CK2 Review
After a particularly good roasting, my stock clutch finally bit the dust and it was time for a new one. I looked at the usual suspects (exedy, cusco, ACT, etc.), but then remembered that WORKS also offers Clutch Kits. I was looking for a single disc carbon clutch rated up to 400 ft-lb with good driveability, and the CK2 seemed to fit the bill. Since the car was sitting on the shop lift all taken apart and I was itching to get it out of there, I was in a bit of a hurry - Oliver came to my rescue and overnighted a CK2, Al flywheel, and SS clutchline.


Everything arrived on time as promised, and went in without a hitch. The guys as Cascade had never seen a WORKS clutch kit before, and commented on the good quality & fitment. For driveability, I was a bit worried about the lighter fly wheel and the single disc carbon/kevlar, but it turned out my concerns where totally unecessary. If anything, the car is more streetable than before - the clutch engages sooner, there's no problem (or burnt smell) when slipping/modulating it on a steep hill, and the fly wheel makes the engine feel almost as responsive as an NA motor.
Just doing the CK2/FW/line easily halved the time I need to change gears before getting back on the throttle, and heel-toe rev-matching is ridiculously easy now. I'm very, very happy with this setup
. MR short shifter is going on tomorrow, after that the car should change gears like oiled lightning!
Was it cheap? No. Was it worth it? Absolutely. WORKS = it works!

Well, the short shifter is in and I've had a week to get used to it now. Like I told Oliver, I think the way WORKS solved the problem of making a short shifter for the MR is absolute genius - I'm not surprised they are trying to keep a lid on how it's done. Considering the parts involded, the price is also very reasonable. That's all I'm going to say about that ...
The shifter does exactly what WORKS promised, it reduces throw in the forward/backward direction by about 30%. It does not alter the position or height of the shifter. It also does not change the throw in the left/right direction, which is a good thing because it therefore does not increase the chances of missing shift gates (misshifting).
That being said, it also noticeably increases the effort it takes to shift. I know people always rave about how the MR 6sp shifts much smoother than the 5sp (which is true), but better is not always good. IMO the Evo 6sp is still very clunky compared to other cars I have driven. After changing the front engine mount (powerflex), the under shifter bushings (solid aluminum), and using lithium grease on all the shift-linkage parts it's gotten a lot better, but with the short-shifter it still takes considerable muscle to get the tranny in gear (picture Frankenstein's assistant throwing the switch ... ). Together with the CK2 and spin fly wheel it does make shifting a *lot* faster though.
IMO the shift effort is mainly the fault of the transmission design, the shifter cables themselves are very smooth. I've tried all kinds of different fluids individually and mixed in different proportions (stock, Redline MT-90, BG synchroshift, GM synchroshift), and that does make a big difference but no fluid has been fully satisfactory at all driving conditions. Synchroshift is great when the box is cold, but gets burned on the track and gets sticky, the stock stuff is horrible when cold (and the gear box takes forever to warm up because of the extra cooling fins), and MT-90 became sticky after only 600 miles.
So while I still miss the effortless "light-switch" feel of my old Celica's 6sp, the WORKS short shifter did get me a bit closer to where I want to be

One more update - turns out one of my shifter cables was damaged, which increased shift effort noticably. I had it replaced under warranty yesterday, and it made a *huge* different in shifting effort. The WORKS SS feels pretty much perfect now!
clutch, fly wheel, clutch line, overnight shipping = 1600 (parts only)
short shifter was 270 including install
can't tell you how much the clutch install was, because I had it done together with some other stuff ...

Well I no longer have my Evo, but I'll also agree, the CK2 was badass IMO, I had that and the WORKS Flywheel and I loved the combo. If I ever decide to get another Evo WORKS will be the only shop to touch it once again, their not cheap but worth it if you ask me.
