Review: Exedy Stage 1 clutch and Fidanza 7lb Flywheel

This review may be a little slanted by the fact that my throwout bearing was COOKED when I replaced the clutch, but I figure it's worth typing up anyway.

Now, I had heard a lot of people talking about how a lighter flywheel can make the car tricky to get rolling in 1st gear so I was a bit worried about driveability. (note that the stock FW is somewhere around 18lb, and the fidanza is about 7lb) For this particular clutch/flywheel combo anyways, I can say this is patently untrue. Clutch engagement is silky smooth, about 1/4 way from the floor, right where you expect it, with no grabbing, no engine stuttering, no drama at all. I didn't have to make any adjustments to my 1st gear starting technique to get nice smooth starts without coming anywhere near stalling. So, with driveability as my main concern, I am completely happy with this setup.

I haven't had a chance to beat on the clutch at all (supposed to give it a 750 mile break-in with no abuse), but I have wound it out in 1st-3rd gear a few times. The motor seems much more eager to rev past 5k rpms--I noticed significantly less NVH at higher rpms. This addressed my second concern, which was flywheel balance. I had read a few people saying that Fidanza wasn't the greatest when it came to balancing their flywheels, but my early impression is that the overall balance of the flywheel and clutch housing seems to be better than my stock setup. Idle might be a bit smoother, but I didn't notice much of a difference in NVH at freeway cruising speed.

One of the biggest differences obviously is rev matching during up and down shifts. The engine is SO much more responsive to slight throttle inputs between shifts. Downshifting smoothly used to take a bit of coordination and thought, but it's a lot more effortless now. A little blip of the throttle and the RPMs shoot up instead of lagging. Upshifting on the other hand takes a little more thought. RPMs drop quickly enough between casual shifts that I have to either be extra quick between the gears or leave my foot on the throttle just a hair between shifts. It reminds me a lot of shifting in the two older miatas I have driven.

The car just seems all around more responsive with the lighter flywheel. It's probably a little quicker through 2nd (I already just spin through most of 1st. lol), but the big difference is the responsiveness, regardless of gear or throttle inputs. It feels like a lighter, sportier ride. So all in all, I am very happy with the Exedy stage 1 clutch and Fidanza flywheel combination, and would heartily recommend them to any owner of a daily driven MSP with power goals in the low-mid 200hp range.

Oh, and just a heads-up for any locals... I got my parts from MAPerformance in Plymouth, and their prices blew everyone else away.
 
im running the same set up. and i must say when i took it on a very spirited cruise through the canyons and mountains of san antonio i was very impressed. thats the only time i have really opened this car up and seen what it can do and this setup was outstanding.
 
quick question for both of you - if you "miss" a shift, say, have a bad rev match that was off ~800 rpm you really "buck" the car on the stock flywheel. is that bucking any harder or softer with the lighter flywheel?
 
i know the buck u are speeking of, it used to do it too me real bad from first to second. but i havnt experienced it in a long time but im pretty easy on my car. i believe it really helped with the issue. the install was an experience there is alot of removing and reinstalling that takes place when removing a tranny on these cars.
 
and i must add the clutch depresses so smooth and easy with this clutch. its less harsh then the stocker.
 
If i wanted to upgrade the clutch, do i have to "balance" it with the stock fly wheel? Id like to upgrade the clutch but dont see the benefits of a fly wheel upgrade?

if i just buy the clutch, i just put it in and go right?
 
dam I have both these parts and want to install so bad but dont know if it will hold once my motor is built, what do you guys think?

will it hold 15ish psi on a gt28rs? aiming for about 300whp.

dont think so.... not by the descriptions? (pissed)
 
i hear that with this clutch and fly wheel combo, that the clutch will wear out faster as the lighter flywheel , being made from aluminum, under extreme pressure can warp a bit. is this true? great write up btw!!!

In general you're going to get less of that bucking because there is less rotational inertia at the crank, so there is less momentum change when the engine speed has to change suddenly like that.

I agree with Outlawstar98. For all the work that goes into a clutch replacement, I'd totally recommend a lightened flywheel as well. This is the first time I've run a lightened flywheel, and I was a bit apprehensive about drivability, but I have seen the light. haha

There's probably some plausibility to that, but I don't know for sure. There's definitely the consideration that lightweight flywheel will heat up more quickly under abuse because there's less mass there to heat up. But on the flipside, under normal driving the clutch is usually absorbing less frictional energy during gear changes, so you could probably argue the clutch may last longer depending on your driving style. I'm pretty easy on the transmission personally, so I'm not too worried about it.
 
glad youve seen the light. i know im really looking forward to getting one... and finally getting a little more of that racecar feel haha.

by the way i figured the bucks werent as bad... thats certainly the theory, but theres plenty of flywheel theory that doesnt translate to application.
 
hows that chattering noise effect thats characteristic of lighter FW, does it bother you on local traffic(stop and go) ?
 
my Fidanza was ~ 4-5grams off. That's a lot for a FW but, you're not going to get any 'wobbling' if that's what you were worried about. It just promotes uneven clutch wear and you might run into engagement issues if you rev past 7,000 rpms. Normal DD's don't really need to balance them (in addition to it costing ~ $80-100), unless your DD is a honda..

anyone wants to review a stage 2? thats what im thinking of picking up

yes please i do not know what clutch to go with, 300whp.

I wanna stay with exedy cause i love the stock clutch, but the description on the stage 2 kinda scared me away.

I remember reading you shouldnt really ride the clutch at all.
