There are plenty of events for Porsche GT4s and M2 Competitions. This is not one of them.

Inflation creates a natural balance of performance. An A90 Supra (2020, $49,900) can compete with a 911 964 (1994, $54,000). Later model years of the same chassis code are permitted.

If drivers arrive without their exact registered vehicle, they will be turned away.
