CMS Drifter: where are u entering drift days every month in WA? I'd be interested to know... The only drift events I manage to get to are the Collie track days or the comps held there. Doesn't quite make it once a month, more like one time at Collie bi-monthly...
Anway like the others said, be prepped to damage your car if you're learning and going to go hard
Cost will include the track day entry and fuel etc and tyres - however I manage to source freebie 15s usually so that keeps $$ down. 16s, not so easy but look around and you'll find some cheap old rubber to score.
As for wear-and-tear, I run a 5puck h/d clutch and stock diff and I've been to several drift comps in collie and track days tehre for drift this year. Sure I may not go as hard as the guys, but even my learning this year thru to gettin better with each attempt I have destroyed any driveline components majorly... yet.
Take care of your car and it'll take care of you!
I hope I haven't just jinxed myself
