Boost the performance of your Sprint or Sprint 2 on wide, flowing tracks with the addition of a Front One-Way Differential! A one-way diff features unique bearings that allow the outdrives to spin in only one direction. This allows the drive axles to turn the wheels to provide forward drive, but doesn't allow the front wheels to brake. This gives the car truly amazing corner speed in fast corners!
Because only the rear wheels are able to brake on a car fitted with a front one-way diff, care must be taken to practice with the one-way because a slightly different driving style is needed when racing with one fitted.
