I think some of your "balanced for racing" ithoughts are perhaps just thoughts. The Tekin ESC weighs 2.6oz total weight - moving this from one side to the other on a truggy will hardly move the "balance point" at all(2.6oz is 1.6% of a 10 pound truggy).
If you weigh the 4s 5500mah g3 pack(21.2oz), one of our battery trays(2.5-3oz) and the ESC(2.6oz), the total weight is 26-27oz for the left side of the chassis. The steering servo, transponder, center diff and mounts,motor mount, Tekin truggy motor, pinion, chassis braces, steering linkage are all on the opposite side and weigh a total of 24-25oz on the MBX6T. This is about a 2oz difference and results in less left/right weight difference than a tank of fuel(which is full in a nitro car at the beginning and empty at the end of a race usually). With the ESC behind the motor as you had it, the balance is within 1-2oz. Neither is very perceptible during driving with a truggy (I am a racer and am pretty particular myself with proper setup).
Now, proximity to the center line of these weighted items plays a role in the actual left/right balance, but the battery(heaviest item on left side) is similarly positioned vs. the center line as the motor and servo position on the right - the result is a quite well balanced vehicle in the end. Add to this the fact that the completed Tekno car will typically weigh 8 or 9 oz more than an RC-Monster converted car, and the "balanced for racing" argument can sway either way.
I haven't done the math on Tekno's kit for balance, but even with a stock chassis conversion, my parts balance out pretty well on the truggy. My regular battery tray can also be moved fore or aft on the chassis to further tune weight bias(front/rear) for additional tuning.
I will be curious to see what your race results yield. Tekno offers quality kits, and their kit descriptions invoke racing confidence(as any product description should). Lap times determines the race winner, though. The Tekno strategy typically yields a heavier car with a well planted feel. The clutch can smooth an otherwise erratic trigger finger as well as impede "pop" over short jumps. The result is usually a smooth transition from nitro, and a well planted ride. Our kit is a bit lighter, faster and more nimble. Personal preference and the end users ability to tune the chassis will also play a factor in the end results. Either strategy can win on race day, but I don't believe there is a appreciable "balance" advantage with either kit. :)
