Effective Immediately—Due to an oversight in the rule making process an important part of the engine ignition system was overlooked. After consulting Ford Racing, we feel the rules need to be clarified and we apologize for any inconvenience this might make being so close to the first race. Several racers have not made this modification but there were some questions regarding it. Thank You and see everyone in Florida!
The following parts are the only NMRA and Ford Racing approved parts for use.
