Members,
I just wanted to share this Basic Spring Rate Calculator and run through how I have been use it.
Guide
SR = Spring Rate
TVM = Total Vehicle Weight
Post build, add your total vehicle weight into the TVW(lbs) box and your front distribution into the Front(dist.%) box. Your Rear(Dist.%) value is calculated automatically. Set your Aero Values in game to the lowest they can go.
From the initial values that the calculator has given you, you can then do a couple of things.
Choose a base line spring rate e.g 60%, you should base your decision on the track and whether you want to go softer overall of stiffer overall(a stiff setup will most commonly still be softer than the original values.
After this if you need to work on a specific end of the car, say soften Front SR, then just choose a value lower in the table from the Front SR column, spend a little time on this part. You can also manually alter the 'BASE' values. This is helpful if you want to add in Aero Values(lbs) to your spring rates or discover a finer more accurate break down of your chosen spring rate, are just a couple ways to use the BASE boxes.
Aero Example = Lets say you settle on 400lbs Front SR, which was 40% on the table and 600lbs Rear SR, which was 80% on the table. Your Front Aero is set to 100lbs and Rear Aero 200lbs. You could add these values to the original base figures respectively(+100lbs to BASE Front SR/+200lbs BASE Rear SR) and the see how the new 40%/80% values feel when incorporating Aero weight, again experimenting here is what its about. There are actually a few different ways you can incorporate Aero into the table by manually altering figures. This is just one way and I'm not saying its best either.
Finer Tuned Values = Lets say you settle again on 400/600lbs Front/Rear SR. Simply enter these values into the BASE boxes manually and you'll get some finer tuned percentages. This will only work for softening the springs. It's important to know that to properly fine tune your springs, nothing beats manually sliding up or down the scale 5-10lbs until it feels perfect(or best possible feel assuming springs are what you tune first).
You can even setup your own list of percentages if you want, try it by changing 80% to 1%. It's quite a versatile tool. Refreshing the page will set the calculator back to default.
Additionally
One of the primary functions of your springs is to support the weight of the vehicle. This means that it is very important to remember such things as Ride Height and Suspension Travel whilst setting up your springs. Personally I would leave the Ride Height at its default and get the springs set first. In addition to using the above calculator I will also make sure that the end of the car, front/rear, that travels the most(furthest) under acceleration, braking, and cornering does not bottom out at all. If it does bottom out then using the in game telemetry, and specifically the suspension travel meters. Manage this by making sure the suspension travel meters(in game) don't fully fill up white at any point - coming close to being full but never maxing out is an ideal setting to aim for in this circumstance and both ends are bottoming out then adjust both.
SETUP CHANGES HERE SHOULD NOT BE DRASTIC! 5-10lbs each time is recommended.
NEED MORE TRAVEL = Decrease the SR
NEED LESS TRAVEL = Increase the SR
At this point feel free to lower your ride height equally and repeat the above using the spring rate telemetry so that you're not bottoming out. If you're bottoming out after lowering the Ride Height it's likely you'll need to INCREASE the SR of the end that is bottoming out. See if your laps are faster and the car feels better. If not go back to your previous setting or go higher in ride height if you like.
Hope this helps at least one person
Thank you

PLEASE ALLOW A FEW SECONDS FOR THE CALCULATOR TO LOAD. REFRESH THE PAGE IF IT TAKES TOO LONG
