HPDE / TT INFORMATION:

All HPDE classes (1-4) on Saturday and Sunday.

ALL participants in the TT run group are REQUIRED to have a transponder. Also, All drivers registering for HPDE4/TT must be pre-approved by the group leader prior to the event. If you have not participated in NASA SoCal HPDE4/TT within the last two years and do not have a NASA Competition racing or TT license, you MUST e-mail socal@drivenasa.com for screening and approval.


PLEASE NOTE TRANSPONDER RENTAL POLICY: Unfortunately, due to 25% of rented transponders not being returned, we have been forced to implement a $50 penalty on transponders that are not returned to Registration on Sunday, 30 minutes after the last session. On Monday morning, anyone who has a missing transponder will be charged $50 to their credit card on file. If the transponder is not returned to NASA SoCal (see Contacts page for address) by the Wednesday after the event, a replacement fee of $400 will be charged.


Also please note that transponders are not rented to HPDE1 and 2 groups as they are not timed but are REQUIRED in HPDE4/TT. Thank you for your understanding and cooperation.
