Hey there guys , have anyone use this combination on a 4G15 here ?

Just wanna get some opinion regarding this . As some said the flywheel should be skimmed as it is heavy , some said if skim will loss top speed ,i'm quite confused ...

Im using Clutch Pump Manual Box from Wira SE , can this gearbox use 8.5" clutch ?

Should i skim down the supertouring flywheel ? if yes how much weight i should target for ? it is intended to be daily driven .

Thanks for any advice from sifus here =)
