Virtually all of the two way consumer dampers we know allow for adjustments in both high speed compression and rebound.

The three ways allow another adjustment in low speed compression and the four ways add low speed rebound.

The easiest way to get to know your 2-way dampers and have a bit of fun would be to set your canister pressures equal at all four corners (say at 175 pounds) and run all adjustments on all four corners down to "zero".

Drive the track and feel your car out, thinking about the track surface. Come in and increase compression on all corners up a notch or two. Drive again, rinse and repeat until the track's bumps and ridges begin to become noticeable or even bothersome. Come in and dial each damper down one notch in compression. Done there for the time being.

Then go out and feel your car out for soft body roll and weight (ahem...load transfer). Continue on with the exercise with rebound adjustments until the car firms up. Go one step further, drive for feel and them come in and lower rebound by two. Done there for the time being.

For fun, you can then lower the canister pressures in all four corners to as low as the damper manufacturer recommends. Drive, feel. Come in and run the cans up to their highest rating. Drive, feel.

For a driver, all of the above should be fun and a learning experience. Be sure to write SOMETHNG down in the book you're sure to carry at all times - before you drink too much beer at the end of the day.

Going the extra step and working the suspension - actually tuning it for speed and individual driver needs requires a bit of work, concentration, good tires at all times and all the other things that REAL test/tune sessions require.

I don't have a nitrogen tank, but I can try the rest of what you suggested. I'm signed up for a David Murry Trackday in mid May. Open track all day...will be ideal for figuring this out.
Thanks

You know I've read that and heard that but it seems counter intuitive because isn't the low speed bump and rebound what affects handling the most? Been doing a lot of talking with suspension folks and reading quite a bit lately and the low speed, being like 0-3 MM (or IN I forget) per second is supposed to be what affects the handling the most. The high speed stuff is supposed to be for quick transitions, bumps, undulations and irregularities. But with most suspensions you feel a real difference in the low speed handling aspect when turning *****.

IIRC 2 way shocks control Low speed bump and rebound.

I had to think about this. Copied this directly from the MCS blurb.

2-Way Custom Double Adjustable - For custom applications and low volume production, or with custom valving typically for a specific professional race series/tire setup (custom valving is not required or recommended on MCS products for most applications, but is available upon request). 15 positions of bump adjustment on the remote reservoir and 15 positions in rebound on top of the piston rod. Each adjustment done to the damper (each click) is very noticeable to the driver. Dampers are designed to perform at both low and high piston velocities, giving you total control regardless of the conditions.

3-Way Triple Adjustable - 15 positions of high speed bump adjustment and 15 positions in rebound on top of the piston rod. The 3-Way triple adjustable damper features an additional 6 positions of low speed bump adjustment.


I note that the 2-way paragraph indicated that the dampers are designed to perform at both low and high piston velocities, whereas the 3-way adds in a separate additional low speed bump adjustment.

And this is also similar to the behavior of JRZ and Moton remote reservoir 2-ways as well.
