Proper way to scale a car???
Doubt you are having the problem with it pulling the wheels off the line and not going straight.
I don't know much about what the ride height will do for your traction, but most cars I see will either be level or have a little rake to them.
The biggest thing I can see is to get the weight off of the nose of the car and get your ratio as close to 50/50 as you can..................that's gonna be hard to do, but I think you could do a lot better that 44% rear with out a lot of expense.
