Welcome to Colorado National Speedway
The Ownership of Colorado National Speedway is excited to announce that we have finalized a deal to utilize the MYLAPS Transponder system for our scoring and line-up processes. Effective for the 2011 race season each competitor at Colorado National Speedway will be utilizing a transponder during each racing event.
Our competitors have asked for this improvement for several years and we are happy to be able to bring this new technology to our facility for 2011. The transponders can either be purchased at a cost of $425.00 each through the speedway or rented for $40.00 per event. If purchased through CNS the transponder will come with an 8-year graduated warranty.
CNS appreciates that this is an added expense and sincerely hopes that our competitors and fans appreciate that this technological improvement is certainly a benefit to all. Every attempt has been made to keep the cost of this new improvement as low as possible, while providing the best system possible. We are eager to implement this new technology and look forward to improved accuracy and a more streamlined scoring process. 
One of the great features of this program is the ability for each competitor to track their individual lap times both during practice and race events through mylaps.com.
Attached below is a request form to be completed for each car/truck. Please Email or fax as soon as possible to the CNS business office.

We will have this program in place for our first practice event scheduled for March 19, 2011. Guidelines for mounting and placement will be forthcoming.
The correct transponder for the system we will be using at CNS is located here. Yet, keep in mind that if you buy the transponder directly from CNS you will save over twenty dollars, pay NO SHIPPING, and get a 8 year warranty.
Transponders will be mandatory for the following divisions: Late Model, ProTruck, G.A. Modified, Sportsman, Super Stock, Legends, Modified Coupes & Super Modifieds.
Figure 8's and Trains will not utilize the transponder system.
NOTE: The red AMB/Mylaps transponder that they use at Cheyenne WILL work with with the new system at CNS.

We are actively seeking sponsorship for this race, to return it to the huge Late Model Race that it once was. Stay tuned, further announcements will be coming soon. Another change will be the combing of the grand American Modifieds and the Modified Coupes into one division. We are excited to welcome back the K&N Pro Series West on August 6th for the NAPA/Toyota 150.

Colorado National Speedway
Colorado National Speedway Ownership and Management would like to announce a division change for the 2011 race season. As most of you are aware, the Grand American drivers were notified that the Grand American division was being dropped at CNS effective 01/01/11 due to a number of factors. After listening to our racers thoughts and concerns we went back to work to come up with a possible alternative solution. After much discussion, we have decided to combine the Grand American Modifieds with the Modified Coupes for a period of 1 year. Both Divisions have struggled with car counts and this will be our last attempt to help build these classes back up to where they belong in order to maintain an individual class going forward. We believe this will enhance the entertainment value of the product we put in front of our fans each week, as well as provide the participants in each of the two classes an opportunity to increase car counts and build strength within their respective divisions.
Each division will run their own rules, and be awarded separate points. We hope this will allow both divisions to eventually return back to separate divisions. We at CNS are excited about this new combination and will work very closely with both CARC and the Grand American drivers and owners to work through the inevitable challenges that will result from this change. We feel it’s the right thing to do for all of our racers in these divisions that have supported our track over the years, as well as our fans who deserve strong, full field classes to watch each week.
In addition, we have unfortunately also found it necessary to drop the Bus class from the 2011 schedule. As a result of these changes, the Figure 8’s will replace the GAM’s as our 5th NASCAR Weekly Series Division, receiving all of the recognition and awards that come with being a sanctioned class.
Look for our 2011 race schedule in the coming days!
Happy Holidays
Colorado National Speedway Owners and Management.
