It does include a clutch, which similarly, I will not be using. I think for your intended purpose, you are making a mistake using the clutch and brake. You will not have ANY shortage of acceleration, so the 2 speed is totally unnecessary as well. Go straight to the FD of the 2nd gear, you will also shed a lot of weight using no brake servo, shed a lot of rotating mass getting rid of clutch bell clutch shoes, brake, 2 speed. I also think the first thing to break will be your 2 speed, probably the first time you run it. Go ahead and try with clutch and mech brake, but I'd bet my bottom dollar you have gotten rid of it after only a few outings.
Why introduce so many additional points of failure which aren't even needed? Even the racing community is split on the value of using a clutch and brake for racing, let alone parking lot bashing.
