thanks for all the suggestions, ive sent my car into my bmw dealership (they are the ones who installed my sc) letting them check everything to make sure everything is in order.
@roman, ambiant temps for that day was around 28-30 degrees C. i set my bmw performance steering wheel to 8200 rpm and shift there. should i be shifting at 8k instead? the course doesnt have too many slow corners. here is the track. back when i did many laps.
ill try the water wetter first. but no way to see if it would work till the next trackday. as the kit is absolutely perfect for any other situations besides the track.
