New to Track Days.

For my 2 Bobs worth, get those pressures down on good sticky tyres. Slicks do it but that means the dollars keep climbing. I've had the view that the white and yellow groups can have the occasional Kamikazi in them (blokes who think they are a Motogp rider but clearly are not). Just ride your own race and cover your corners.
Remember the 2 metre rule. I suffered 2 lengthy lectures from officials at PI, a third meant a a ban for passing too close. They were right of course, the Rule is there its for safety and also not scarring the crap out of people. I've stuck with the Red group since and behaved.
If you find Track Daze is for you, leave the roadie in the shed and get a dedicated track bike of your choosing. Start with a cheapie then work up.
Most of all have fun but always think about apexes, braking points and your traction control (wrist)

Cheers
