Hi Ray,
I recommend a combination of AX and DE days for the first season to really develop skills as a driver and working traffic. Once you qualify you can participate in Time Trials (racing against the clock) at a pretty high level without major changes to your car. When you are ready for Club racing it will be time to strip and cage your car, add fire suppression, containment seat, fire suit, add a trailer, tow vehicle, tire rack with multiple sets of wheels and tires, spares and tools etc. Each level up the ladder is significantly more expensive and requires more commitment.
Rough cost estimates based on average participants:
AX- Quality tires and alignment $1k
TT- Track prep suspension, brakes, cooling, reliability mods, safety gear, multiple sets of comp tires and spares. $10K
Club racing- Fully prepared race car with all safety gear, spares, trailer and tow vehicle. $50K
Welcome to the slippery slope.
