So you’ve bought a set of coilover shocks for your car with spring pre load (or “spring tension”) adjustment, nevertheless do you know the right way to properly placed it? Possibly your coilover system doesn’t have distinct ride level adjustability, quantity it to yield some desired trip height, and so are now just hoping the set pre load is due to proper range. Or maybe your coilovers accomplish have springtime pre load adjustability distinct of trip height item adjustability, but you happen to be unsure of how this has an effect on performance. In this posting we will probably describe the consequences of spring pre load and how they can properly placed it.

Having too much or perhaps too little springtime tension will probably negatively impact suspension effectiveness, but in different ways. Too much springtime tension might make your delay, pause feel like it is certainly topping away. This is really because now the shock reaches its optimum length far too suddenly, and this may sell your trolley wheels from the road surface. Not enough springtime tension might make your delay, pause bottom away excessively. Learning these effects can help produce the correct changes.

Let’s define a few conditions to help understand spring pre load effects. The amount of heart stroke the springtime consumes within static trip height in the weight on the vehicle is called “droop. very well And the sum of heart stroke left over within static trip height is called “compression heart stroke. ” The total shock cerebrovascular accident is droop and compression stroke combined.


Total Shock Cerebrovascular accident = Waste + Compression Stroke

It is essential to understand that springtime tension doesn’t affect the springtime rate of the linear springtime (most coilover systems come with linear springs). For example , raising spring pre load WILL NEVER increase the solidity of your linear spring. Still this WILL boost the amount of compression heart stroke you have that increases bottoming resistance.

Nets on most coilover systems have to become pre packed in order to hold on to a desirable sum of compression stroke within static trip height. For example; if you have some coilover along with a 200 lbs/in spring pace carrying 800 lbs of weight, without any pre placed spring pre load, the coilover will probably compress 4″ just in the static 800 lbs of weight working on it. Whenever this coilover has a total of 5″ of heart stroke, this simply leaves you with 1″ of compression stroke left! In this predicament you must pre load the spring to insure you have got more than 1″ of compression stroke. There exists way too much droop in this predicament.

So we now know that springtime tension has an effect on droop. But some of us wonder what is the proper amount of droop to obtain? This varies depending on how much total heart stroke your coilovers have, and so we deal with the desired droop as a rate of total shock heart stroke. In order to have a proper amount of droop, we all recommend setting droop to become 30-40% on the total zap stroke (see equation below). Now you realize that you have to modify the springtime tension in your coilovers to yield 30-40% droop!


Desired Waste = Total Shock Cerebrovascular accident x. thirty five

How to placed spring pre load:

You first have to measure the entire shock heart stroke of your coilover (including the bump prevent length). After that measure how much the coilover compresses when the vehicle is in static trip height. Take away the compression stroke within static trip height in the total zap stroke to get the droop sum. Adjust springtime pre load until delay, pause droop is certainly between 30-40% of total shock heart stroke.


Waste = Total Shock Cerebrovascular accident – Compression Stroke
