Told you already Turbo
dump the oil out of the shock and note the stick from the o rings by pushing the piston back & forth.
Anyone including a rocket scientist can feel the stick from old swollen seals.
Try this , before you replace the old seals ?
Check your ride height..
After you replace the seals recheck the height.
Car's ride height will be higher and need to be reset.
Hope this helps you.

So I finally broke a front arm last week and all they had was carbon. I really don't want to run them other than a tuning option so I still need front arms. Anyone tried the RPM arms? Tempted too since the seem like they would have to add weight up front. Also seem to remember them being softer. Still trying to find a little more front grip.

Im looking for a bit more, not to mention I'm amazed it took this long to break a stock arm. Still trying to get around without having to be marshaled. I haven't learned that the tenth I save being 2 inches closer to the pipe get lost when you hit it.

The amount of force being applied to the shock shaft, is far greater than any stiction would impede. We are talking about a steel shock shaft being slammed through a rubber o-ring, with 4+lbs of weight behind it....that's on compression. On rebound you have a spring with 3.30lbs (white kit spring in rear) of force behind it forcing that shaft back out again.
That's enough pressure to push that same shock oil through 2, 1.6mm holes fast enough for our cars to handle good....and I am supposed to believe that the TINY amount of friction on two lubricated surfaces is going to make a noticeable impact on the shocks performance???? It's not like when the RUBBER o-ring expands it's putting more friction/force/pressure on that STEEL shock shaft.
See why I believe this is more of the "butt dyno" thing than real life scientific fact?
And out of curiosity, I looked up the term "stiction" and by deffinition it ONLY applies when the shock is stationary...there is no stiction while the shock is moving. So basically that throws the stiction theory right out the window all together.....
"Stiction is the static friction that needs to be overcome to enable relative motion of stationary objects in contact.[1] The term is a portmanteau of the term "static friction",[2] perhaps also influenced by the verb "stick".
Any solid objects pressing against each other (but not sliding) will require some threshold of force parallel to the surface of contact in order to overcome static cohesion. Stiction is a threshold, not a continuous force."

BTW, I haven't noticed this effect with Big bores. It's strange, given o-rings are the same.

In my experiences; which are rather brief so far with the B4.2 any lack of steering issues are usually related to having too much rear traction. At least for me it has been. But also front tire selection can be an issue as well. For me it has been a learning process and I am still learning!

Soo I opened my shocks today to replace the oil after a month of running 2 days a week....... I guess I should have done this sooner it is really dark brown. lol ahh well I still won on thursday night

I have Integy pliers and they suck. I just use small needle nose vise grips and the edge of a towel. Never scratch and they hold tight. It's also more convenient to have them locked solid when I'm putting rod ends on so I can measure with calipers to get equal lengths.
