In addition to short-course off-road racing, Jenkins Brothers Racing competes in the SCCA MX-5 Cup series. The popular road-racing series places a premium on careful car setup and precise, efficient driving, as the spec-class rules make certain all the specially prepared Mazda MX-5 race cars are as close in performance as possible. Racing graphics aside, the cars appear nearly stock but are modified for racing with stiffer suspension systems, boosted horsepower and full roll cages for safety. Both Mike and Mark Jenkins compete in the MX-5 Cup series at popular road-course venues across the country.
