Z4M roady @ thunderhill (video)

Alright... I guess I will be the first one since no one has posted any roady track video.

NCRC event at Thunderhill. I just mounted Dunlop Direzza Sport Z1 Star Spec 245/275 on the stock rims not long ago. the car understeered a bit due to incorrect tire pressure. A little bit more PSI tweaking should help rotate the car better.

Comments and tips are welcomed...
