There is a correct amount of crossweight for every combination of setup and weight distribution for your car. If your car needed 51 percent and you run 52 or 53 percent, the car will be tight. There is no need to change springs to try to loosen the car. You need to lower the crossweight by taking cross or wedge out of the car. The correct procedure is to balance the car with some amount of crossweight distribution and then read the left-side tires. If the LF and LR do not have matching tire temperatures, start changing spring rates, moment centers, and so on to balance the car. As the balance is corrected, the crossweight must change with the other changes to maintain the handling balance.
