I'm in the same boat as you. This is the game plan that I have for myself for next year.
I would have to say full race gear should come first if you don't have it already because safety is number 1.
- 1 piece suit
- back and chest protectors
- race boots
- race gloves
- helmet obviously
I have all my gear already, so right now I'm focusing on transportation for my bike. I don't want to ride to the track because it's inconvenient, and a trailer is neccessary in case you can't ride back for some reason (injury, damaged bike, too tired, etc.) So right now I'm shopping around for:
- Trailer hitch
- Trailer options (uhaul rental or buying my own)
- Bike tie down options for both rental or personal trailer
Next I would take care of track REQUIREMENTS.
- Tape for lights
- Taking care of any safety wiring
- New tires
I'm not at the level yet where I am out-riding the stock parts like brakes, suspension, or stock power so I'm going to leave the bike as-is in terms of performance mods. But I will try to get the stock suspension tuned for my weight. I believe that the biggest improvements to lap times will be to the rider, so I will be signing up for more rider training.
- Setting up stock suspension by a professional
- California superbike school level 3 & 4
- Comparing "local" track organizers and their schedules to my favorite tracks. Comparing their costs and how organized they are.
If mid season I see myself becoming a regular track junkie, then I will be shopping for race bodywork, race tires, lap timer, and tire warmers. But I don't think I'll be buying anything other than race bodywork in 2009.
