Honestly? None... Steve ran a stick car harder then anyone I know. In one year he broke 11 Jerico trans. He then went to Liberty's. And had 3 ready to rock. One in the car one spare in the trailer, and one ready back at his shop. He makes well over 300 runs a season, and he just flat out got tired of working on the car nonstop.

Here is what the car launched like on every pass when it had the Libery 5 speed.
