well, i dont plan on really slamming my tour, my main points are to even out the fender gap, gain some stiffness for the corners (street driving) and have the freedom to go all the way back up (for what its worth on GCs) when the ohio winter rolls around. which is why i dont think i will necessarily need konis, because i would guess my lowering wouldnt exceed 1.5" on the GCs, but thats plus/minus a less than an inch to even out the fender gap. i can't figure out the big difference between spax non-adj. and bilstein, but for the price of bilstein (only vendor i know is SP-@ 122.50/corner) i might as well go koni (i found them for 152.60/corner) so on 1.5 inch lowering, +/- a small amount, do you think the spax would be up to the job then?
