Decent set of tyres a must. You dont want to lose control around a tight hairpin corner. Not sure what mods you've done to your ZRE but it would help if it was lowered and had decent tyres. More stability and handling prowess. Front strut brace also is just absolutely magic. Engine oil, check beforehand esp if your going to be travelling a fair distance to the track. Plus check all other fluids that may need attention, being 09 zre if you've kept up with your servicing then you should be okay. As with what daryl said, CAMS or ASAA race licence. A helmet that is also CAMs approved. Mine was 25bux on EBAY ftw! I got half face one, i think full face will hinder me a bit. First time on track with helmet is quite daunting and can get quite hot and uncomfortable, but as the day progresses you get used to it. Brake pads! Your brakes will get a good workout on track, brakes and tyres for sure. Also check your tyre pressure. Lower tyre pressure will give you more grip. I had mine on 40 to start with then dropped to 37psi all round on my RE001's 215/45/17 tyres Empty all unecessary things from your car beforehand or put into a personal box. Your car has to track fully empty and stripped, spare wheel/jack/tools and all. No loose objects in the car/cabin/boot. Do this on the day, not beforehand. lol Drinks, food/snacks, money. Thats about it i think. Just take it easy the first few laps/sessions, get a feel for the track, learn your racing lines and braking markers. By the end of the day, you'll definitely be improving on your time. Have fun and enjoy yourself.
