These comments are for lower grip asphalt tracks and not for carpet.

Use the 3 hole pistons and leave out the red sponge. You'll have to use 2mm more of spacers than you would on the #54000shocks cause the shock bodies are 2mm longer. This is why this shock is smoother than the shorter 54000. Build them as a 0 rebound shock. With new bladders this is impossible to do, so drill a #60 hole in the plastic end cap to bleed the trapped air. Depending on the amount of droop you want, the shocks should be 56-58mm in overall length, measuring from end to end.

If the above isn't clear, you can PM me on the subject. I've posted this stuff before and just don't have the patience anymore to discuss this with those who don't agree with my methodology.
