I want to adjust my rear koni shock harder for 18" wheels. How do you get the bump stops out. It seems like they would get torn up trying to pull them out. They don't seem to move easily.

why would you want to remove the bump stops? if you want a firmer shock, replacing the bump stop isnt the way to do it.

Grab them with two long needle nose pliers, one on each side, and pull. To the second post, you have to remove them to fully collapse the shock in order to adjust them

And if it's an OE Koni or Koni Sport, only the rebound is adjustable

i misread, I could have sworn the OP was talking about bistiens. nevermind!

I sprayed a lot of lithium grease in there and was able to break them loose.

However, upon further inspection, I found the right side shock is rebound much slower then the left side.

Yes, OE Koni's. Are they shot?

This work bench dyno test doesn't really tell you much as you haven't developed enough force to even open the valving. More than likely one shock has a bit more stiction between the piston and the top seal which doesn't mean squat to it's actual operation. With that said, if you need new Koni's we'd be glad to help.

There is a pin hole on top of the shock. Use a hanger to push the bump stop out.

Thanks. I figured as much but wanted to confirm. As far as actual damping is concerned, they seem to be working fine.

However, the ride is stiffer. I wonder what impact too much dampening and not enough spring rate has. Does higher spring rate and less dampening achieve a better ride on the street? I do not track the car.
