Important Stuff To Read Before Proceeding

Before entering a car which DOES NOT have an RMVR logbook, review which situation below applies to the car:

  • Cars without an RMVR or VMC logbook:  These cars can be entered but must be of special interest to vintage racing and largely conform to RMVR years of eligibility. You can review here our detailed criteria for such cars before entering.  When asked for the car's "class" please select “Exhibition." .
  • OR as a special" Gateway Run Group" car: This is for race prepared cars of any class which must have a logbook from a recognized wheel-to-wheel racing organization When asked for the car's "Class"  please select “Gateway."  Please review the following criteria to enter this special "Gateway Run Group."

All "Gateway" entires 1) must be closed wheel and have a current logbook from a well-established and recognized road racing organization, 2) must be nicely prepared – NO LEMONS, and 3) must pass an RMVR Event Tech Inspection and meet all RMVR safety requirements..  Regarding Fuel Cells: as long as the vehicle has passed preparation rules regarding a fuel cell (or not requiring one) by the organization issuing the logbook, the vehicle will be allowed to run in this Gateway Run Group..  Drivers entering the Gateway Run Group must also hold a valid up-to-date medical exam AND a current Competition License OR a Provisional License from their home organization..

  • OR you are a Provisional Student with a waived car:  Recent RMVR competition school graduates may enter the same car they used during driver's school even if it has yet to obtain an RMVR logbook . It will run in our regular RMVR Run Groups. This exception is granted to aid the Student in obtaining their full Competition license. When asked for the car's "Class" please select “Provisional Student's Car."

RMVR requires a fuel cell for all cars racing in our regular RMVR Wheel-To-Wheel run groups If it doesn't have one, you won't be allowed to complete this entry. There are four exceptions. If the car meets any of these exceptions, please check "Yes" to the registration's Fuel Cell question.  This will allow you to complete your registration:

  • If your car has an RMVR Historic Class designation.
  • OR if your car is part of an invited "Spec" run group and your Spec Rules don't require a fuel cell.
  • OR if you are entering the "Gateway Run Group" and your host organization (i.e. who issued the car's logbook) does NOT require a fuel cell.
  • OR if you are a recent Competition School Student with a Provisional License running a car newer than 1981 which doesn't have an RMVR logbook.. 

For Double-Driven cars:  If you are sharing a car with another driver for the weekend, just have the one person enter.  Only that one entry fee will apply.  To avoid another entry fee, simply CALL THE CLUB ADMINISTRATOR, 303-319-3062, to advise who the second driver is.  Don't try to enter that second driver online.  The second driver MUST also go thru registration Saturday morning and have a valid competition license and medical. Thanks. 

When entering you may be required to pay a Membership Fee to complete your registration.  It will be good for the entire year.  After Labor day your RMVR membership will also be good for all of the following year.
