On Road Shock Rebound
 

never found a clear answer on why some people prefer little to none and some like a lot. does it have to do with the track being smooth or bumpy,and I understand it is up to the driver but I am looking for more info. I watched a nice video of DJ Aprilla (Capricorn Driver) build a set of shocks with like 1MM
of rebound.thanks ,always trying to learn more,mike.

It seems the rebound is more to do with the level of traction available on the racing surface. High traction - less rebound. Low Traction - more rebound.

You may find this video interesting. He discusses the difference from 9:40 and shows you how to build shocks with differing amounts of rebound from around the 5:10 mark.

Hope this helps?

thanks dan,very informative.suprised no one else replied,mike.

when traction is low i generally run 1 spring softer but go with more rebound to get a more progressive ride

For a soft spring setup with lots of travel it would assist the downward movement of an arm into a divot on the track. Rather than the shock resisting the spring, a little rebound can help with responsiveness. Rebound would have less effect in a short travel stiff setup as the spring would do most of the work and have enough force

Rebound is something wich i don`t like personally because:
- much rebound needs a leakfree build of the shocks wich is hard and will give more shaftmovement resistance (not so smooth),
- it will give a diminishing effect on the spring/arm stiffness because of leaking.
- chance of left right unequalness (tweak) in the car,
- more hassle on handling issues.(checking the rebound left right),
- effect for me personally is small and messes with the spring choice.

smooth or bumpy is droopwise changes with springs.
high traction: keep the car low
low traction :let it roll more.

Just my way/opinion
