I am working on getting my car scaled. My left % is about 54.7, rear% is 52.5, and cross is 56....exactly what is cross weight and how is it figured. What does a person need to do to change the cross% without changing the left and rear percentages. Any advice welcomed.

Cross will not change left or rear %. Shoot for 47-49% cross, then play with it some.

We have tried to add up to 200 lbs to each corner of car one corner at at time and the cross never moved much more then 1%. Nothing we did really seemed to change the cross% much. The scales are brand new also and have been checked agaist scales used on other cars.

hey stealth
Cross is more a result of spring preload than moving wieght around. Adding spacers under lr spring increaces cross removing spacers reduces cross.You could also work withy any other corner to ajust cross.

Actual corner weights would be good too.

Yes stealth every corner matters check all four corners on ride heights and i am sure you will find the problem. If you raise your left front you will take out cross and left % a good height to start with would say. lf-7 lr-7 1/2 rf-7 1/2 rr-8 Look at your weight or scale car without weight and add weight to center if you have to much left %. Give these guys numbers and we all can help a little. Have a good one

The only way to change left or rear weight % is to actually add lead weight. Cross weight change will not change left or rear %. Other than a couple of pounds due probably from chassis bind.
