How Do You Measure the Corner Weight of a Vehicle? If adjusting a coilover, doing so could affect ride height, so changing the spring rate might be needed to arrive at the optimum corner weight balance. If you need more weight on the right rear, you will either have to adjust the left front coilover to get more weight on the right rear, or change that front left spring rate to make it happen. Many racing setups call for preloading the suspension, and when you preload a suspension, you’re playing with spring rates. How Do Vehicle Scales Help Determine Coil Spring Rate?Ĭar scales will show the corner weight balance of the vehicle. Many car scales feature adjustment screws, but you can also use floor tiles, or anything at your disposal to arrive at a level vehicle scale. Then, using a construction-type bubble level or laser guided leveling system, make sure each vehicle weight scale is level.

First, before you put each corner weight machine in place, make sure it is free of debris on the bottom because even the smallest piece of tape or pebble will throw off any measurements and repeatability. Each corner weight scale must be level to get an accurate and repeatable measurement. In that case, steps must be taken to provide a level surface for each individual vehicle weight scale. However, we know that won’t always be the case. Many shops we know work hard and spend the money to make sure their floors are perfectly level. Having the car race ready gives you a baseline, and then you can make your adjustments from there. The vehicle must have the stagger set, all ballast firmly bolted in and the rear end properly square.

This means the car must be full of fuel, radiator topped off, oil in the engine or oil tank, etc., and the driver in the car or the driver weight simulated, as well. The most important part of using race car scales is that the vehicle must be in race-ready trim. With that, the race car scales do the rest. Using ramps also easily allows you to roll the car on and off the scales to check accuracy, as well. The ramps, especially if at the track, make it easier to get the car on the scales with minimal effort. In this manner you don’t have to make sure the springs have settled since you didn’t unload the suspension. When doing so make sure to bounce the car up and down to settle the springs before going through the weight process.Īnother way is to use ramps or slim pieces of wood the same height as the auto scales. If you don’t have access to a lift you can jack up each side or the front or back and then lower the car onto the auto scales. Some people use a lift to raise the whole car, then slide the scales under each tire, and lower the car back down on the race scales. Auto scales allow you see the weight of each corner. Vehicle scales are four individual plates placed under each tire to measure the weight at each corner. You can adjust weight balance, shift weight from front to rear and side to side using these race scales.
Car scales allow you to dial vehicle weight and balance at home or in the shop so you’re not chasing suspension setup at the track. What that means is to have the car ready for optimum handling, weight distribution, and maximum grip either at the launch or coming out of a corner before even putting a tire on the racing surface. What it means to scale a car is to have the car’s suspension set up for competition even before arriving at the track.
