First thing I did was get 4 sets of scales and put a wheel on each with the car sitting level. I counter balanced side to side first by putting 20 grams in the pod next to the motor pinion. Next I added 50 grams under the servo 120 grams under the Lipo's. I then placed something like 100 - 120 grams under the speedo. This gave me something like a 67 - 33 % split. Think i had to add 10 grams at the front bulkhead and a couple of 5 gram weights about to fine tune it in.
Here's where it gets tricky. I weighed in at 1740 with a 65.6 - 34-4 split. After running this and moving some weights about i finally settled for 1708 after removing 32 grams from under the lipos. At my first regional the car weighed in at 1760 grams. I then weighed the car at work on calibrated precision accurate scales and got 1690 grams. I weighed them on another set of scales and got 1725.
I think your never going to get the ideal weight spot on but the 35 - 65 split is crucial. For me i think its about 37 - 63 on dry grass outdoor and slippery indoor tracks.
