building up my drift car has got me hankering for some grip racing... I wanna build my 1000 2 door sedan into a track car, but I dont know where to start - what classes could I race in? what engine capacity brakes etc etc do I need to compete in said class, I am 100 percent commited to getting the mighty 1000 on the track but I need some help to get started... any one?

Go for it!
Supersprints are a great place to start. They're cheap, common and you don't NEED to be quick.

You'll need a CAMS licence. Visit their website. Fill in a form and pay the $80 bucks or so and you're good. Then you need head-to-ankle-to-wrist cotton clothing, (Some guys just wear jeans and long sleeve cotton shirt), enlosed non-nylon shoes (dunlop volleys from K-mart ok) and a CAMS approved helmet (start at $90). Um.. fire extinguisher might be mandatory too??!!

The supersprint will cost you about $175 for the day and is mostly insurance and track hire fees.

Contact your local track and ask who the contact is for the next scheduled supersprint.

cheers dude, I already got the stuff like helmet and that, I just eant to knopw whether I have to stick with the a10 or am I free to go a12 a14 etc, is there a site or something you can link me too?

most categories will have the lowest class as
0-1600 cc,so an a15 is the best start to get close to the class limit,but an a14 will be just as good.the a10 only has a 3 bearing main crank, so it's not the best start,& you can't fit bigger cranks.the best bet is to go into you're local cams office & see if they can tell you what categories the local club racers run to.they can also point in in the direction of an active club.get a cams manual at the same time.i know here in nsw they have about 6 different categories,standard,road registered,
improved production,sports sedan, openwheelers & sports cars,then a class for all the wrx's,evo's,prb's,etc.all these have capacity classes at the same time.
