The usual extra info on this series exclusively for the Alfa Romeo Giulietta TCR...
There are 55 events (53 Trophy + 2 TT) and the rewards 25-50-75-100% are split 8-13-18-27GC.
At its LTS completion PR of 47.1 you can get to 75% with more in reserve...
To complete the series 100% requires upgrade pattern 5334334 costing a further 102GC
[EDIT] that pattern/cost based on original required PR49.6...now only 49.4 needed = 5343343 costs 10GC less.
Thanks to SJA for pointing this out - sorry I never noticed
