Talk:RR3 Wiki:Upgrades Strategy For 100% Completion/@comment-80.110.66.94-20160630195119

I reached the last two 10 lappers in Endurance Kings without spending any GC for upgrades on any of the cars. I won the Porsche 919 (2014) by completing RTLM and bought the other 2 LeMans Cars for GC during sales. So yeah, I spent GC (a lot), but none into upgrading.
