Expose Var to bp

VehicleMovementComponentW4, the clutchstrength under transmission setup.
Want to build a quick driving simulator (vr and wheel with stickshift) since the driving schools here are locked down and my car is a piece of junk thats probably gonna break down if my girlfriend stalls the engine more. Got everything basically done except for the clutch. thank you for helping btw!
