back which loosens the car. Putting the left rear radius rod in the top hole on the rear end will allow the left rear wheel to come ahead as the car rolls into and through the corner. This is caused by the left rear radius rod going from a near level condition to a 10-15% angle. This also loosens the car. A common practice to help a car that has an entry and apex push is to put the rods in these two positions and run a spring rod on the right rear radius rod which will let the right rear walk ahead under acceleration. To tighten the car back up while still letting the car roll into the corner and through the apex with the rear having “negative” roll steer, to help eliminate a push condition.

Right Rear Radius Rod: A. A solid link will not allow the rear end to move front to back, except when body roll occurs. B. A rubber bushing in front of the right rear radius rod will allow the right rear to move ahead approximately ¼” under acceleration. This will tighten up the car and let the right rear move back while braking for corner entry, which will loosen the car. C. The spring rod is very popular in asphalt modifieds. Depending on the rate of the spring you use, the spring rod will allow the right rear to move from ¼” to 1 ¼”. This has the same effect as the rubber bushing, but on a larger scale.

Tracking Right Side Wheels: A. Always run the same sized offset wheels on the right side. B. The most common way to check this is to use a string. C. We recommend measuring from the inside of the rear wheel to the out side of the chassis. Square the front tire to the chassis and measure from the inside of the front wheel to the outside of the chassis. The measure ment should be equal on 1997 and newer cars. There should be a 2” dif ference on ‘85-’96 cars.
