Re: re:
Scaling the chassis and setting the corner weights is all part of the initial chassis set up. It doesn't reflect on the quality of the build although the better the it's built the easier it will be to set up. Usually you will try to start with the rear weight close to even and make passes with the car to find out what it needs. If it goes to the right you need to add weight to the right rear.
It would be better to use scales to do this. The reason I suggest disconecting the 4 link bar is because it will preload the chassis and that will affect corner weights. You want to try to set things up where the rear weights are close to even and you don't have to worry about the front corners, it won't make any difference with how the car leaves. If you want to increase the weight on the right rear (and it looks like you should) you can either adjust the left rear down or the left front up. I have found to offset the driver weight and set the rear even usually adjusting the left front up is the way to go. If the front is higher than what you want you can drop the right front to have the same effect. The weight will change diagonally.
