actually, junglegym on HS.com has the pro-kit/koni yellow setup and he has 1.5" gap (he has pics of it) in front and a little over 1" in back using the middle perch. the standard koni yellows for 5th gens have 3 perches that are 1" apart. the neuspeed editions of the koni yellows have 5 perches that are 0.5" apart. i believe junglegym has the regular yellows w/3 perches. i got the pro-kits already but a group buy for the neuspeed yellows for $475 fell through...now i'm back to choosing between yellows and bilsteins :angry:
