Haha, no no I would never nor recommend going over the posted speed limit, ahahahahahaahaha. Nor would I recommend street racing either, lol.
Glad your enjoying your car. Here's a video from a Performance Clutch company I've been talking back and forth with, and it will clear up your clutch for you. Forgot to tell you, twin disc clutches are easier to push and smoother to use, for the driver, but inside where we don't see, even though it is so easy to push, it grabs much harder than a tradition single clutch which is why the Viper, Corvette, GT500, Camaro, Challenger....have switched. We just need to get used to the differences.
