This is a large topic indeed. Then again, IMO, it is small. Personally I think PAG got it right generally. I stick to factory parts and upgrades. Depends on how you use your car. For street driving I am very content with stock set up on my Carrera. Track would possibly be a different story.

Donīt know about the SC. There are some upgrades that are well invested, like the Carrera cam chain tensioner.

Better informed will join in soon.
