I updated up to a maximum of 8 levels of R&D parts (Rear Wing, Cockpit, Brake Disks, Engine block, Steering wheel), and then found new parts for these R&D parts,why? What is the purpose? What's the point of this, if I upgrade to the maximum and then I get new unnecessary parts? It would be better and smarter to receive parts for other R&D parts that are not upgraded to the maximum, so the game has some sense and purpose.
PLEASE, make an end (maximum) of parts that we can achieve for each R&D part! And when you acheive it you should not receive any more parts for that R&D part.
Thanks & Best regards
