Sorry I did not reply. I'm not a regular in this forum. Anyway, after replacing those parts, I've been using the car for about a year (only race tracks) and have no issues with engine and transmission.

Again, the standard m235 oil system is not designed for the race track use, this is why its cup version M235R has M4/M2 oil system! M4 and M2 are made for the track. If you did't have any oil starvation problems, that only means, that the track that you are driving doesn't have multi apex long corners and you are not experiencing g forces for extended period of time. Or you just not fast enough in the corners.
