I was following your posts. One of the most important thing to do is to use this link

Street Performance & Racing Spring Rate Tech | Understanding Spring Rates | QA1 Suspension

From QA1 to figure out your spring rate ratio. My kit came with Coil overs and springs...The front was ok but the rear springs were almost a 100 lbs too strong do the leverage and angle of the shocks.

Knowing what each wheel or at least each axle weight is also very important. You can use the scales at a truck stop and just pull the front wheels on and then the rear axle to get where you are at.

In my case I ended up with 53% rear weight but do to the length of my rear trailing arms I still needed lighter rear springs than the front. My kit came with all 4 the same weight.

Hope you enjoy tuning your car.....Ken
