To continue, you’ll need to know the how much weight is on the front suspension. Not too long after I bought the car, I weighed it on our Longacre scales. Curb weight (without me in it) is a hefty 3,983 pounds. There’s a combined 2,282 pounds on the front axle and 1,701 on the rear. We realize most of our readers don’t own scales, but you can get an accurate enough number using a public scale. Dividing the weight supported by one front wheel (1,100 in my case) by the force ratio determines the spring force for that wheel (1,571 pounds for my car). To be very precise, I could weigh all the unsprung components (wheel/tire, brake components) and subtract that number from the total amount of weight on that wheel.
