Im trying to find the perfect ratio of added weight for behind/ in front of rear axle Well, I've heard people say 4 ounces on back axles and 1 ounce on the front axle. I personally try to put all if not most of the weighting material just in front of the rear axle for what ever ratio that works out to be. I might use the small area behind the rear axle to fine tune the weight of the whole car.  HyperDrive |

The physics of weight placement will only determine an ideal location if variables are held constant: - shape/design of car
- steepness of slope to transition
- length of flat track from transition to finish line
.......so there are many different types of ideal weight placements |

Im trying to find the perfect ratio of added weight for behind/ in front of rear axle I don't know about weight ratio, but I like to get the balance point of less than 1.0" in front of the rear axle. On a nice flat aluminum track that is...The rougher the racing surface, the less aggressive you want to be. |

I agree Mike, on a smooth aluminum track, have COM less than 1" in front of rear axle. Maybe about 1 1/4" to 1 1/2" on a very rough track or else make sure your alignment is dead on with anything less.
