Interesting way to look at it.

Having higher compression rears makes the rear tires load up quicker, and having high rebound rates on the front will effectively slow the spring and wheel from falling to the ground, which takes the weight off that wheel quicker when excelerating out of a corner.

The same is true for braking and turn entry. The rears have less rebound which keeps the rears in contact with the road for longer, and because the fronts have lower compression, it takes longer for the weight to get transfered to them. To put it simply, there will be less oversteer upon turn entry and you'll get better rear traction when exiting. Too much can cause the front end to push when excelerating out of a corner though.

Considering the FB's handling trates, the companies setup these shocks up properly. IMO

Don't forget, shocks handle changes is suspension movement, braking, initial turn in, acceleration on turn out, uneven pavement. On a steady corner with no bumps, handling becomes more about spring rate. Shocks are more about transitions. I'm sure most of you know this stuff, just making an observation about the graphs. Good information!

i havent weighed my car, or picked a ride height either. i have measured some of the stuff like the swaybar, but it doesnt use that in that calculator for the shock numbers.

bubbles you will feel...
gotcha ...

Still open for doing other shocks if anyone is willing to spare them for a bit of time.

I've read a couple of books on chassis/suspension. Basic books, but they explain things well. IMO konis are better than Tokico's. Even the 5 way single adjust Koni's that I used to run. I've also run tokico 5way single adjust before. They are slightly better than stock, but probably best used for spirited street driving.

Also, single adjust struts/shocks usually adjust rebound only. Double adjust is for rebound and compression. You can see that on the front shock compression chart. Rebound was the only thing changing.

the idea being you need to put the values from YOUR car in there, and see what
shock position fits best.

i have another spreadsheet, its much more involved, but since there are only 5 adjustments to the shock, it might actually be quicker to drive the thing, you could spend hours on the spreadsheet....
