LONESTAR: There is something very goofy with your numbers. If you check your numbers before you made your adjustments, you have 775 for left side weight and 670 for right side weight. After your adjustments, you have 725 left and 720 right. The left/ right totals only change if you move weight in the car or add or subtract weight from the car. Spring preload will not change them. Your final numbers are surprisingly balanced, only 5 grams heavy left. Stock TC3 can be off by well over 50 grams on the left.
