A huge part of it is tires and foams as well. I know Ryan loves to run the CrowBow setup with the new Profiled foams. The Crowbar in the front has amazing on power steering. This tire gives great on and off power steering but allows you to put the car wherever you want with a little throttle.
Then on the rear we usually run the Crossbows. The crossbows provide amazing forward bite but allows the car to rotate crazy hard. However, as soon as you lay throttle to the car it snaps straight and you are good to go. Look how well his car straightens up when on throttle.
Definitely take the tires into consideration.
