Additional costs would just be $55 fer a CAMs licence fer a year and the maintainence of your own car...i just did my first track day on june 6th organised by mountainrunner and i recommend it strongly fer anyone who wants to have some good healthy fun with their cars out on the track...i went there without really knowing anyone but made a few friends and even had advice from a couple of guys who go to the track regularly, best way to learn is to go out on the track and drive...
I had all my fluids and oils checked before track day too..Make sure u have enough meat left on yer brake pads and thread on yer tyres, and brake fluid too....i flushed and filled up with Motul RBF600 just before track day and by the end of it, my brake fluid tank went from max to half...i pretty much exhausted my front brake pads and wore my tyres quite a bit on track day... but that was with getting about 30laps on the day..Last thing u want is to go to track day and end up not being able to enjoy driving on the actual day cuz of problems that could be avoided/rectified before it....
Pity i cant make this coming track day...but put me in fer the next one in Sept! Cheers~
