Gravity GT12 Tweak Wheel Inserts

While the quarter-drop method of measuring if your pan car is tweaked works reliably with foam tires, you may find yourself running out of patience when using it to work on a rubber tire GT12 car. Because these tires balloon as they age, the tire can become unbalanced leading to inconsistencies in finding and correcting tweak. More than once we've found ourselves chasing our tails to correct what we thought was a tweak in our GT12 only to find we just had an unbalanced tire and we weren't getting the tire in the same position every time. Our GT12 Tweak Wheel Inserts eliminate this by staying attached to the tire in the same position while you tweak the car. As an added benefit, you won't have to balance the quarters on the tire each time you check either. Simply press the insert into the spokes and position them to point forward. Then lift the car from the middle with a wrench and notice which wheel moves first. Adjust your suspension to correct this tweak and repeat the process until the wheels move at the same time. Sold as a pair.
