Never trust the percentage. If running weight is 1320, your tolerance should be 6 grams (aka 0.5% ) for target fore-aft, lateral, amd cross weight. After you determine the weight placement to get it balanced the way you want, before you hit the trwck the cross should ideally be 50-50 or your car would act funny. Dynamically, the cross and the fore-aft dominates. You could have the lateral off a bit but if the cross is ok, it will still drive fine. But if your cross is off, forget it.
