First post so be gentle!!
I finally managed to do Suzuka in the Nomad Diablo, after playing around with the setup since I found it really tricky in the wet. I then stumbled upon a Suzuka race whereby it started raining on lap 4 instead of 3 and didn't get wetter than 30%, actually stopping raining on lap 8. (Previously it had always started raining on lap 3 and got up to 57% wet). Managed to win by 12 seconds staying on on Soft slicks.
Completed Spa first (well second time after a hasty restart to change the gearing) in a 787B on rain tyres. So much faster than the other cars as the race wore on, even overtaking 3 at one corner (pouhon?) in the wet!

not sure how much I won by since it stopped counting, maybe 40+ seconds!?
Doesn't spa look beautiful when the rain stops and the sun comes out at the end of the race???
I've not attempted the other race yet but will probably try it in my GTR first.
I've only managed bronze in the time trial so far too....
