The Kyosho Inferno GT cars at SS Raceway in our “Spec” class race every weekend. The 2 speed works very well for us. The majority of our cars use the 15/19 clutch bell set-ups and shifting is not a problem. We have a lot of fun with them.
The cars equipped with the 14/17 gear set do seem to shift too early, but once they go to the 15/19, they're good to go.
Most of our racers are looking forward to racing our “Spec” cars at the 3rd Annual US Open Sedan Championships at Kissimmee this April.
