Choosing clutch (ACT/Xtreme) and flywheel (Competition/Driftworks)

[noperope]

I'm currently in the market for upgrading the clutch and figured I'll go with a 6-puck clutch to get a bit more bite as I'm primarily going drifting. The car currently produces 500nm and I'm standing between getting either an ACT clutch (https://www.autoextreme.co.uk/act-clutch-nissan-skyline-r32-r33-gtst-heavy-duty-race-sprung-6-puk-clutch.html) or a Xtreme KNI24007-1B. I'm currently running a fullface clutch so I'm aware about that there will be more bit with a 6-puck. However, I'm wondering about ACT vs. Xtreme, I've been trying Googling but due to their generic names it's not easy.

As I'm changing the clutch I figured I might as well get a lightened flywheel and it's current standing between a Competition ultralight flywheel (steel, 5kg) or a Driftworks flywheel (chromoly, 8.5kg). 3.5kg is quite a difference but the materials are also different, which I was curious if anyone could provide additional insight to.

Thanks in advance guys :)

I'm an ORC/ os giken man myself...looked at theirs? Great clutches, come with moly flywheel.

I cant comment on the other but I used Xtreme one with chromoly fly for good couple of years drifting with similar / more power and did the just just fine !

Dont know where you live but currently using NPC - they built a single plate to my required specs - decent $

Unless you've substantial power upgraded, any clutch will do that is not stock to a degree like what you've mentioned. Until you're going to a multiplate, whatever really. Makes more sense for twin and up as a flywheel change is a given, unlike singles.
