Maybe I dont have so sensible ass, but for me there is no difference at all even by reving engine on neutral. I am using ZF (Sachs) single mass, organic kit at the moment but 8-blade disc on photos was part of NRC development kit I got. It looks like NRC first kit (pressure plate + disc) didnt want to cooperate with stock dual-mass fw. After couple of weeks I will transport my car from Poland to Germany and NRC will get back their clutch + full Oem kit. I am 100% sure that they will use whole feedback and there will be one of most durable clutches coming on to market soon. Single-mass flywheel + 750 Nm cover plate + 8-blade (usable on street too) sinter disc with damping springs with lowest price on market.

Sachs is a big no for me. (Current experience with my Leon II with a loba/sachs kit rated at 750nm which I can easily slip on 3rd gear @1.8bars of boost - my high is 2.5bars)
Single mass flywheel and lower rotational mass there does make a difference. Since there is lower inertia, I guess rev matching at upshifting should work better.
Many smf kits have noise (chatter) so it is not unexpected.
For me - If I ever change the flywheel/discs/pressure plate, I would go with a twin/triple plate kit.

Whell, when I had Mazda 323 1.6 turbo, I put Fidanzda fw and stage 3 clutch and my engine didn,t rev much faster and I also didn't notice any change from original fw
For me, there was a huge difference when I swapped from the stock Beta Flywheel and clutch to a fidanza with an agressive street clutch in my Tiburon (Coupe, rd2). That car died in 2011, but ircc, the weight savings of the fidanza over stock was somewhere in the 10-12lb range.
It was very noticeable, even after months of use, the engine would rev much quicker, shifts were easier to manually rev match.

It is a bit odd that these parts are available for the 1.6l Turbo Gamma (Elantra GT N-line), and not the more performance oriented 2.0l Turbo the I30N and VN get. Maybe it's because the Gamma has been in production longer, idk.
SXth engineering is selling them though.
So here is something interesting I learnt about why it is so damn hard to change gears fast in the i30N without it jerking. It's because of Rev Hang which I heard of before (and not sure if has been discussed here) but never really understood, until I read this article:
https://www.carthrottle.com/post/rev-hang-explained-and-why-petrolheads-hate-it/
I absolutely hate the fact that I cant hammer it and change gears quick without it rev hanging and hence, jerking, especially from 1st to 2nd gear!

Really? It doesn't jerk when you change gears quickly without waiting for the revs to drop? Could this be different between the i30n and veloster N or do they use the same engine and gearbox?
It could also be the whole emission restriction as its quite high here in Australia. So maybe its tuned to rev hang more here? I wonder if anyone else in Australia has the same problem.
Ok interesting. I know for a fact that mine rev hangs and my guess is that it is how Hyundai Australia tuned it for emission purposes. It would be interesting to know if any other owners in Australia have experienced this.
Do you guys have issues with Rev Matching, keeping up with some downshifts? Especially from 3rd to 2nd sometimes?
Seems to happen to me every now and then, it's like the car cannot rev match as quick as it needs to. I have also noticed how it rev matches when you select a gear at times, but other times it does it when you have selected a gear and then start to release the clutch, which obviously causes a delay. Not a very consistent system that's for sure. My other i30N didn't do this, it would rev match as soon as I moved the shifter towards a gear.

Personally I file Rev Matching in the "its a bit shit" box. It may be wonderful for track driving but for road use I've managed to change gear quickly for almost 25years without having it available.
I also wonder about drivetrain longevity with these systems.
I sound like a parott with this but anything other than Normal setting and it makes me cringe a bit lol.

Same thing goes for the start/stop system... how long can the car endure such "punishment" (for some people)? Personally, rev matching smooths my drive a lot and do like the extra blip on the downshift to ear the exhaust note. As for start/stop, first thing to go off every morning. Sifting wise, not a problem on my MY2018
Yup. I've noticed it from 3rd to 2nd too. It's not very often and always does the job but it does indeed wait untill the last possible moment to rev match sometimes. I use it all the time. I know how to rev-match but the system does is perfectly every time and I don't have to think about it at all. When hard braking from lets say 120 mph to 20 mph I downshift through the gears as fast as possible. I get loud pops and bangs on every downshift without even touching the accelerator pedal. It feels very satisfying
Yep same here. It's not good for the car, just another emissions BS. I wish the car could remember it's setting or that it could get coded out somehow.
