Q:Any reason why you went to a lay down for dirt? More forward weight, steering, rear sticks less etc vs layback
Matthew Gonzales: In testing, the Layback has ALOT of a "roll" affect. No matter what I tried the car wouldn't stop rolling. I like grip but the Layback had a weird grip feel to me. The Laydown is "faster" for me. As I'm well aware of what it does and you can add and take away grip in the car as needed.

Q: Is this the setup you ran yesterday at Coyote?
Matthew Gonzales: I ran this same setup with 3mm on the ball stud mount to get the car to roll though the sweeper.
