And its not completely old school, I actually use my phone now instead of an actual calculator
Can u explain the formula u use to figure out ur sertings? Im sure plenty of people would like to know
Sure. I guess assuming everybody knew it was dumb. Sorry about that.
Okay. I'm sure there are other ways of figuring it including if you would like your suspension a little softer as this method does make for a pretty stiff spring. But, like Johnson said these are flash tunes or I always name them either base or test.
IMPORTANT. Do this step AFTER your build.
1. You will need the curb weight of your car -you can find this on the upgrade page
2. you will need the weight distribution -this is also found on upgrade page but is represented as front only and its a percentage and is found by toggling the Y button once
( ex. POWER 493
TORQUE 567
WEIGHT 3237
FRONT 58%
3. Take the weight of your vehicle and multiply it by your front percentage,,,in this case it is 3237 X 58% which equals 1877
4. Ive seen this step debated but I always do it (it's weight) you take that total the 1877 and add your front aero value to it. If it's a track that favors grip I run full aero so it would be 1877 + 100=1977
5. Repeat step 3 but with your rear percentage this number will be 42% (FRONT 58% so REAR 42%) Why? because your weight distribution should always equal 100% so 3237 X 42% =1359
6. Repeat step 4 in this case we will say its full aero which is usually, but not always, 200. So, 1359 + 200 = 1559
7. Take the numbers you got from steps 4 and 6 and simply divide them by 2 Why 2? because you have 2 springs in front and 2 in the back.
So FRONT would be 1977 divided by 2 which equals 988 Plug that number into your front spring slider on the tuning page
REAR would be 1559 divided bt 2 which equals 779 plug that number into your rear spring slider on the tuning page
So, what do you have after you do this? A fairly stiff spring set up. But, in theory, a perfectly balanced spring set up. If I remember right I think guys were knocking off percentage points from the front and rear in order to get softer spring rates. I almost always have to lower the values so when I do, if I were to do this one I would take the front down 58 points at a time and the rear 42. Basically knocking off a percentage point from each.
And there you have it. I think. It's late and I'm tired so if I missed anything or something doesn't make sense just post it up. And if I'm doing it wrong post that up to so I stop doing it
