Performance Racing Industry
Dear Attendees,

The Performance Racing Industry (PRI) Trade Show will not take place as scheduled in December.

We sincerely appreciate your commitment and support of the PRI Show. Despite health and safety guidelines that were being put in place, mounting uncertainty related to the Coronavirus has resulted in an environment that would not be conducive to a productive trade show.

Without reasonable assurance that the experience could be reliably delivered, the announcement is being made to help exhibitors, attendees and partners plan appropriately.
