Transmission and Drivetrain
Modular Mustang Racing has 10+ years of 5 speed knowledge to bring you the strongest, most reliable high performance line of transmissions available today. MMR owner Mark Luton is the driver, builder and owner of the 2000’ Red Turbo Mustang, and is the current record holding fastest 5 speed transmission Mustang with an 8.99 @154. This was no easy feat and on his way to this record we learned valuable information that no transmission builder today can match, we have pushed these transmissions to the limit and know exactly what it takes to make them live in our customers cars on the street and at the track. Each unit is hand built by MMR and serial numbered for quality control.
