haven't nor do I plan to lower my civic as I already tap my mud flap pulling out and into my driveway. but for every car I've lowered in the past, including a 95 Civic, 2 94 Accords, my 03 Trailblazer and my 99 firebird, I did it myself and rented the spring compressors from the local parts store using the loaner tool program Advance Auto has or in the worst case (after I had a pair of spring compressors slide and pinch my hand one time) I removed the coilover, took it to a shop and had them swap the springs for a nominal cost of like $20 a piece or something like that.
