When we first announced that we were working on So Dialed, a lot of folks started asking for what is essentially a troubleshooting guide - how to fix common handling problems.
As we have been cataloging various settings and what they do, we just worked backwards to try to come up with just such a guide for y'all. Here is what we came up with - there are a bunch of handling conditions, each with a list of remedies you can try.
The remedies are not necessarily in order. We tried to prioritize, but every car is different, and other settings may affect the ones you are working with. So, please use this as a list of things to try - don't feel like you need to start at the top, you may want to just start with whichever is easier to implement on your car.
We will have a similar guide available in the app when it launches, because it isn't always convenient to look things up on the web.
Also, please note, some items here are only relevant to off-road (like jump handling, etc,) so please make sure the advice is relevant before applying it to your situation.
With all that said, good luck, and we hope this helps!
Reduce understeer
- Thicker rear anti-roll bar / thinner front anti-roll bar
- Softer front tires / harder rear tires
- Higher rear roll center / lower front roll center
- Harder springs / heavier shock oil / smaller shock piston holes
- More Ackermann angle
- More caster
- Increase shock angle (less upright)
- Bias weight towards the front
- Less trail
Reduce oversteer
- Thinner rear anti-roll bar / thicker front anti-roll bar
- Harder front tires / softer rear tires
- Lower rear roll center / higher front roll center
- Less Ackermann angle
- Less caster
- Decrease shock angle (more upright)
- Bias weight towards the rear
- More trail
Increase on-power steering
- Less front toe-in
- Thicker rear anti-roll bar
- Increase caster
- Lower front roll center
- Less anti-squat
- Longer wheelbase in rear
- Thicker fluid in center & front diff / lighter fluid in rear diff [4WD]
- Use laydown transmission layout
Increase off-power steering
- Less toe-out
