Why do you think you need more high speed rebound, but not low speed?

 

With low speed rebound I think I would end up loosing traction over smaller bumps where with high speed it'll eliminate the over extension that I'm getting over certain bumps. low speed rebound feels ok as of now but I still have more driving to do.
A larger brake or end stack washer is what I'd want to do so I don't really change the way the stack works right now on low speed.

I do need to reduce compression a bit in the rear so maybe that'll help reduce the hop that I'm getting. It might just be an issue of comp vs rebound percentage split?

It rides smooth and has really good control especially in front and I think if I take out a bit of rear compression it might be fine.

 

Traction is controlled by bump not rebound. You might want to rethink your valving. I would try more low speed bump vs less if you have wheel hop.

 

That's what I did but you were saying it was too much compression. Maybe there was confusion?
I'm guessing I've doubled my low speed compression over what I was running on with the last revalve and steady state traction has increased.


Rebound = traction killer on the backside of the bumps



Less bump from what I have now but I still have way more bump than before.

 

I don't remember telling you anything about your valving before the last post, but I have been following your progress.

I'm not convinced that the suspensions reaction to bumps is anyway related to rebound.

Over extension of your suspension sounds like a chassis issue and should be approached from the rebound, or spring, side of things.

If you could make both your bump and rebound curves more digressive I think you might like the results.

 

hahahaha, sorry about that. For some odd reason I was thinking of Rob (random1) when I saw your sn. Ooops

 

I understand the other stuff for the most part and appreciate all of the info but don't understand this statement.



Any ideas on how to make a shimstack more digressive?
Does a thicker base shim create a more digressive curve?

 

I have no idea how to valve any shock, I just know what I want the dyno to look like.

What I'm trying to say about bumps and bump (compression) is that they are directly related and I don't think rebound plays much into how the shock reacts to bumps.

 

Rebound can prevent certain hops after bumps. Just imagine a damper without any rebound and what the car would do.
I know that the tires can't hold the car down but I think high speed rebound can control the spring a bit better and prevent the overshoot without having too much low speed.

Let me know if my thinking is wrong.
