MMR Spec racing is to keep cars in close racing and grow local club racing.
The number one reason we see racers leaving is when the class they run becomes too fast or too expensive to compete in. We often find by specing the class you continue to grow the class and racers enjoy being able to keep in touch with the car and we see a need to keep the class slowed down. The fast racers will always be fast regardless of Spec so do not fret if you are a hair off there pace.
By no means does the MMR Spec take away from or change any current running class in this case USVTA rules but we add to the rules to increase driver turn out and help maintain current racers in the class. Always remember if the spec class is too slow there is a class already that goes fast, uses the most current in tech and is for the elite hard core racer.
You may also find as we have many are already running a similar type spec in the class and this will allow them all to openly promote a race standard for there events.

Monitor the front post for changes as with all racing the spec is modified to keep the cars in check and as motors, batts, speedcontrollers all change we will adjust as much as possible to continue to give you the most fair standard of racing we can.
There is nothing much more exciting then watching a VTA main were multipule cars are on the exact same lap pace and jocking for position, taking multipule attemps at passes, making runs in short shoots to muscle the line into the next corner. Side by side action through the sweepers for finishes that are meer inches apart across the line. Were a slight rubb on the wall can cost you position & thousands of dollars in support parts are not required to be in that mix.
