Yup, 10gc is all that's required (the upgrade build mentioned above isn't required, you only need 2212231 - where the 3rd tyres upgrade is a R$61k upgrade following the 10gc tyres upgrade). This gets you exactly 48 PR and lets you get the 25 trophies to unlock the Fusion.

It's still well worth it and it's a gold-positive series (+60).

Incidentally, the 100% strategy guide entry for this series is currently out of date (states no gc cost).
