your best bet is to get a set of tyres identical to the control set used for the winternats;
36R sorex
medium c inserts
sorex dish rims with no mods to rim

there is no point trying to set up a car on shit tyres cuz then when you wack a good set on the car will be totally different. also if you can afford it, try to go down to the actual track and get some practice in. there is no point practicing at a track with a totally different surface, well that's my opinion anyway, some might argue this. there is a race meet at guest park on the 22nd, this sunday!


from here go to a base setup. if you can find the base setup for YOUR style xray, use this, try looking for a high traction, large track setup with either a sunny or cloudy/cold setup.

then try either of these setups, then decide which is best and do small tweaks from here;

this is a good page to find setups.

wd40 and tyre warmers will help of you have them or can borrow it. if no tyre warmers, just use wd40. but before using aditives try the tyres with nothing as the aditives make it initally very slippery and might confuse you even more. ie use additives once it is dialed, and ask a experienced racer how to apply it and then clean the tyre.
