997 Carrera 3.6 Mods

[RED110T]

Hi guys

Quick couple of questions if anyone can kindly assist. I've got a 2005 Carrera 3.6 and would like thoughts on the below mods and where best to source them:

- single mass flywheel (want that mechanical chattering noise when idling)

- short Cup gear ratios - what exactly do I need?

Many thanks
Peter

Fantastic, thank you both, very helpful. I wasn't aware it was more involved doing the gearing on non-GT3. I was very fortunate to own a 997 GT3 RS a few years back and it had the shorter cup ratios and compared to my C2 daily, its quite funny. I can literally read a page of PH forum thread before I need to change up from 3rd to 4th : ) ah yes good point also re the LSD, cheers
