Really Helpful Tuning Flow Chart!!!

I told Beef and a couple others about this and promised I'd post it up so here's what I was talking about. For a tuning dummy like me this is really cool

"Does [front|rear] roll excessively?".

I'm not sure I could identify that happening. What does that...mean? I believe I understand body roll but I'm not clear on when you know it's too much.

This is badass btw, thanks for sharing it!

Roll is too much in FM4 when you notice it... Wink

Think Roll like and aircraft... turning is Yaw... "dive" (under braking) and "squat" (under acceleration) are pitch

lol! I would say that too much roll in the back is when you can feel the car start to hook itself around the corner when you're exiting, not enough would probably be when your tires break loose in the middle of the corner without the hooking effect. As for the front, I really have nothing...

OK.... Marm has called me out...

How to identify too much roll in FM4....
  1. Run 4-5 laps in Hotlap and save your replay
  2. Watch the reply with the suspension telemetry up
  3. When turning and transitioning, you are looking for a lot of "transfer" side to side (more than 1/4 either way) and spots where the car bottoms out on one side (not front to rear)
  4. Adjust this with your REBOUND first then Spring Rate and not the ARB. ARB is for fine tuning.


Remember.... The stiffer the suspension (less transfer from side ot side) the faster the car will transition. Softer the suspension (more transfer side to side) equals more mechanical grip at the cost of transition speed (time it takes the car to change direction).

The trick... Finding the sweet spot! Wink

Hmmmm, everytime I touch the rebound / damping it seems to make things worse so I've always avoided it. Suppose I'll have to start playing with it again

BTW... I love the diagram...

I also love the Tuning guide by VVV Worm on the FM4 forums... I actually created an offline file I use for reference, which I sourced from the VVV Worm post...

https://docs.google.com/file/d/0Bz4OFHHLsSxmdXRZQnlaS2ZMdW8/edit

Stating in Page 5 are the lists I use the hell out of. It's a lot like the diagram, but more detail...

I assume the BS in that stands for Beef Supreme...?
