I tried searching on this, but got nothing helpfull. My question is will lowering a prelude with ATTS do anything to the ATTS? Will it still work fine. I don't want to lower much more than an inch. I just don't want to do anything that will mess that up.

When I worked for Honda there were a bunch of preludes w/ ATTS lowered that came in for service. Some with the ATTS light on but driver related not suspsension.
