Queries About Damping

Hey everyone,

I’m looking for some help and advice regarding damping. I’ve been a long time forza fan but a very recent tuner. (2-3 months). I’ve read and re-read the excellent tuning guides by both worm and dltuning. I’ve visited the forums often and have read some of the great posts by ERS Johnson, RPM Swerve, PR Kid, Caesars Wrath, gtFOOTw, just to name a few. I feel that my basic understanding of how the various tuning aspects work is OK…all except damping. I understand what the Rebound and bump is.
I’m struggling to even know where to begin with this part of the process at times regarding the values. Should I take what the stock values have to offer and work from there or are certain car types known to have favoured rebound/bump ratios? If I change the front/rear Rebound value does the front/rear bump need to follow suit and vice versa? I think I’m struggling to grasp what the numbers even mean in this area lol if that makes any sense?
I’ve no doubt got more questions but I’ve gone blank at this moment in time lol.
Any advice would be really appreciated. Cheers guys!

Hey everyone,

I’m just bumping this up if anyone can help me out. I signed in with the wrong account on OP hence different tag now. Really appreciate anybodys time with this, it would be a huge help. I think I just need to find a way to process this part of the tuning a little easier in my mind.

Or if anybody can recommend any clubs that wouldn’t mind me tagging along at some point and maybe share some insight and advice. Cheers.

My take on it.

Rebound effects understeer/oversteer when care is transitioning. (Accelerating through turns. /under breaking etc)

Apply the same thought process as you do ARBs
Lower front/ compared to rear to get more over steer on rebound amounts.

I’m not a tuner like some of the others but that how I’ve come to understand it and seems to work out

Hopefully some one comes along and explains it better

I’m probably not going to explain it better, but I adjust damping based on whatever the rear end of my car is doing. If I’m losing the rear end around medium and high speed corners, increasing front rebound damping can help. If I’m losing the rear end when turning on trails or cross country, increasing front bump damping can help.

I’m generally pretty stiff with rebound damping and pretty soft with bump damping. I have a tendency toward understeer with rebound and oversteer with bump. Depends on the car. Trucks and hatchbacks generally better with understeer. Sedans with oversteer.

I think the differential is more important when “transitioning.”

Cheers for the reply guys, appreciate your take on it. I’ve definitely found it one of the more confusing parts of this whole tuning process. I think it’s just getting the confidence in fine tuning these aspects and knowing what I’m changing or applying is making a positive impact on the tune.

I always appreciate any help or advice on tuning anyway. It really helps me along the way and get a better understanding.
