Our clutch and flywheel shares the same as the Mitsubishi CA4A MIVEC so we're in luck. The stock clutch plate has a 215mm diameter. Lotsa imported options available including Alcon, Toda, Cusco, Helix Autosport and Exedy. If you want to go local you can always try Triniti. I decided to upgrade my clutch to an Exedy Race item while having the transmission stripped for my 4.592 final drive install. The Exedy option is reasonably price at only RM880 (was RM950 when originally introduced to the Malaysian market) for the clutch plate and clutch cover. There are however a lot of fakes floating around so shop with caution. Price is not everything. Also despite what other mechanic or people might tell you the Exedy/Daikin clutch that you can buy with the blue/grey cover is NOT a performance clutch. That is the standard Exedy Daikin oem replacement clutch. Only those Exedy in red boxes are race/performance items. Picture below of Exedy Race Clutch Boxes
The Exedy Race clutch plate comes in 2 flavours. The 3 puck full race version and the full face round organic race/performance street version. Both use the same clutch cover. I would really recommend the full face clutch plate unless you have an all out race car and want that little last bit of grip as :
1. You can actually slip the full face clutch and the car will not judder when taking off from standstill
2. The 3 puck clutch plate wears out really fast. The material on the puck is really thin and some of my friends have had their clutch fully worn out within a year
Picture below of Exedy Race Full Face Organic Clutch plate for Mitsubishi F5M22 gearbox. Part Number is MD05S. The springs on the plate (which are required to cushion the impact when the clutch disengages from the flywheel so that you will not have an on/off effect) are really beefy compared to the stock item.

Oh.. before I forget I also decided to change my stock rubber clutch hose to a stainless steel braided teflon lined item from Goodridge. The effect is the same as upgrading your stock rubber brake hoses giving you a firmer and more precise clutch pedal feel. You can get the Goodridge clutch cable from Pentagon Enterprise via my bro Chris Tan.
I also decided to replace the clutch release bearing with a newer Proton oem item - Part Number MD706180. The Exedy clutch does not come with it's own release clutch release bearing. However there are reports of some shops selling the Exedy with the clutch release bearing. Not too sure on that. Perhaps some of you out there running the Exedy Race clutch might wanna comment on this? My bro Jack even got a nice vinyl "Exedy" sticker to go along with his clutch set. I never got mine. Bummer! Oh ya.. The stock flywheel also got replaced with a lightenened one piece chrome molybdenum Jun item and likewise the stock open differential with a Kaaz 1.5 way Power Pot Limited Slip Differential but I'll talk bout that another day. Installation took my mech about 2 days due to the number of parts being replaced. However if you're just replacing the clutch it should not take more than a day. Picture of the flywheel and clutch installed to crank before the gearbox bellhousing is mated to the engine block.
Overall I would say the clutch pedal feel is only about 10-15% firmer than stock. No big deal as you get to exercise your legs more. As stated earlier the clutch is very driveable and you can slip it like a stock clutch. Advantage is that it doesn't slip that much!

My clutch is slipping like a bitch. This eleventh-hour pre-event discovery really isn't happening at all!
Our sponsor Triniti will not supply us with a new clutch until after the R3 TA 2006 event.
Arrgh.
Why the long wait? Get an Exedy first lar or if budget permits Alcon ;)
after the TA 2006 event means after all 5 rounds? if lidat, get another clutch 1st loh... hate to see u lose seconds cox of a damd oem clutch.
i try the 3 puck exedy before on 4G93 mivec with std fly wheel
first week after install, when coming out from the car left leg will shake a little bit, esp after traffic jam. after that is get used to it already.
1 month later was fall in love with it and thinking manual g/b should have the feeling like that.
1 year later was feeling some slipping from the clutch, but still driving it. the respond of the clutch is start to decrease.
another 6 month, it slip like hell, 3rd gear 2000rpm and step on the gas, the rpm climb but the speed will lag about 1~2 second. feel like driving auto g/b.
when remove the clutch and have a closer look of it, clutch pad worn out until cannot see the pad identifation line, clutch cover and fly wheel worn out with a very deep groove on the pad contact surface. something similar with soft material brake disk with metal pad. need to change the new pad, pressure plate n fly wheel.(ouch!!!)
now using std clutch n pad(cannot tahan every year change clutch), will have some slip when driving hard. start to miss the exedy feeling. will give the full face organic version a try after this set "tapao".
anyone try the organic version before? can share some experience ar?
