Ride height is the way to keep accurate notes about the adjustment of the rear suspension. Be sure to have the same air pressure in both tires for accuracy. Our baseline is 273⁄4 inches. Ride height is the way to keep accurate notes about the adjustment of the rear suspension. What's Next? Grizzled racing veterans have told us many times that you aren't really working the suspension until you have 600 hp. We read that as, “you aren't doing wheelies until you have 600 hp.” And wheelies are what we want. Since the stock 302 is telling us through oil-pressure readings and subtle coolant use that it wants out, we are going to add a Ford Racing 363-inch crate engine to the car and see if we can “work” the front end off the ground. Stay tuned. On a factory Mustang, the center of gravity is 21 inches off the ground and 42 inches behind the front axle centerline. if you remember high school geometry, you can use formulas for a scalene triangle to figure out the static position of the IC.

Stay in school. Rules of the antisquat If your car... is heavy has a numerically lower gear ratio uses a big tire makes no torque Then you should: Hit the tire harder using an IC above the antisquat line If your car… is light has a numerically higher gear ratio uses a small tire makes a lot of torque Then you should: Soften the hit using an IC below the antisquat line In this sequence, you can see the car hitting the tire hard and immediately moving to the right (from the driver's perspective), as the rear dampers fail to control the speed of the car's rotation and the sway bar and front suspension allow the passenger rear tire to rotate up into the body and unload. As the car moves through the frame, you can see the nose dive as the front suspension fails to slow down the weight transfer to the front of the car, bottoming out the suspension and starting the second bounce, again unloading the tires. The MMS parts solved all these problems at once and gave us the ability to fine-tune the car.
