About this event
Welcome to NCR Autocross #4!
This event is open to any licensed driver but a few slots are reserved for PCA members. Unfilled member slots will be made available to wait-listed drivers.
Determine your NCR class before you register. NCR classes have changed this year and are different than other regions. You can find the NCR Class Chart in the NCR Autocross rules. Non-Porsches are classified using SCCA classes. If you need assistance, contact the registrar.
The registration form includes an optional donation to Devens Loaves & Fishes, the local food pantry. Please help us support this worthy cause. Learn more about Loaves & Fishes. With your help, NCR raised over $5000 for Loaves & Fishes last year. Please note that we have kept our rates low but we sincerely hope that in return you will contribute at least the suggested donation to Loaves & Fishes. NCR will match registration donations to Loaves & Fishes (up to $5000 total).
