Thinking about getting the sports springs from Drive Gear. Had the wheels off this weekend cleaning everything up before winter and it didn't look like it would be to hard of a job to replace the springs. Anyone done it and what's involved, any special tools needed. Also, can't find much on these springs, anyone know what the drop is, dealer said 3/4" to 1", which is what I'm looking for, don't want to go to low. Thanks, and yes I did search first but could not find anything.
