We have invested in a Westhold timing system this season, and transponders will be available to rent for: Spec Panther drivers Instructors Advanced HPDE drivers Intermediate HPDE drivers with approval In HPDE run groups, drivers will only have access to their own times, and transponders are only to be used as a supplemental educational tool. Any drivers found to be engaging in competitive behavior, over-driving or otherwise inappropriately using transponders may have their privileges revoked. No refunds will be provided if transponder privileges are abused and revoked. At this time, only rental transponders are available to be used with our system, there is no option to bring your own, or permanently purchase transponders. A $200 replacement fee applies to each lost or damaged transponder, this will automatically be charged to your credit card on file with us upon failure to return, or loss/damage of transponder(s). AutoInterests is not responsible for transponders lost or damaged due to insecure mounting. Each driver is responsible for securely mounting their own transponder(s). Rental Cost: Qualified HPDE Drivers: $30/day $350/season Spec Panther Racers: $30/day $200/season We have a limited number of transponders available, and they are available to rent on a first come, first serve basis. Rental will be available online in the coming weeks.
