I didn't go from ae springs to Kyosho springs. I switched completely to Kyosho shocks. I didn't notice a difference between the Kyosho and ae once I got them set for me. Only thing I noticed was that the aes leaked with the new seals and the Kyosho didn't. Old ae shocks never leaked and these didn't until I put new seals in them. I found a set of old seals left over from my rc10t3. Fixed the problem of leaking. I then switched to the Bbs and once again no difference other than they didn't let the car bottom out. I ran the car as fast with all the shocks I just liked the look of bigger shocks. and the same goes for the truck and 44 too.
