I'm trying to decide between two nearly identically-shaped bodies this year which will allow recessed 1/4" tungsten cubes. My question is has anyone done comparisons between running a 9/16" tall car which can have a double-stack of 1/4" cubes vs. a lower-profile 5/16" car which will have a single, but longer stack of cubes. What's better - having a tighter weight distribution (between the wheelbase) which will reduce angular momentum losses as the car goes through the curve or having a lower profile car with more angular momentum loss but better aerodynamics?
We'll be running on a 35' AL BestTrack. Thanks!!

Thinner car, single stack of cubes with cubes all the way to the back of the car

I agree single stack will be better than the double stack weights do like 5 kid said start with your weight as far back as you can and you can even have the weight be the rear of the car cut the wood all the way out.hope this helps

Thanks for the feedback, guys. I can get the COM to almost 1/4" of the rear wheel axle. How far back is too far back?

1/2 is the most I have played with it takes alot of tuning there to get it stable if you do not have a track I would go with 3/4 to 1 inch to the center of the axle hope this helps.

I have found a COM of between .35" and .50" far too aggressive for my track. I have to use a very large drift to keep the dominant wheel on the rail and I still get some rear wobble. I moved one car's COM from .35" to .50" and it was better but still got some "W". The opinions of most racers of .75" down to .625" (5/8") seems to achieve good results. The more you reduce the COM the more drift is usually required - at least in my experience.
