justin st13

Currently building a st170, was gonna get rid of it but owese over 1500 on parts and starting to see potential init.
The clutch has just slightly started to slip.

Now then. I plan on itb cams and that over the next year or two so want a clutch that will handle this.
I see on the Internet about these stage 1 2 3 clutches, and lighten flywheel.
Have seen that there is a vibration problem but as it not a daily and more a toy and it a problem for me.

Which stage do you guys recommen?
An where can I buy a clutch and flywheel.

I gonna change the master cylinder ect while ie got her apart.

Another quick question. Port and polish. Are they worth doing? I work for a machine shop where we do powdercoating aswell. ( powdercoater by trade) so can get it done for free.

All advice is great full.
