Riding on the bumpstops in not safe, the tires can become airborne. Not to mention the damage it does to the struts and the terrible ride/handling. If you're going to lower a car do it right or don't do it at all. The only time springs should be cut is when there are no aftermarket springs available, the market is flooded with Civic parts. The first rule for suspension: DON'T BE CHEAP. Some things you can be cheap with. Your ass can't feel a difference between a $20 intake or a $200 intake on the other hand your ass will defintaley feel the cheap springs. Stay away from cheap coilovers, buy a decent set of springs & struts. If you lower more than 1.75" you WILL need camber kits or frequent tire replacement. Don't forget to have it aligned after lowering, even if aren't using camber kits. The toe needs to be adjusted. Toe in will eat up a whole tire while negative camber eats up the inside edge. There is a cheap way to fix rear camber issues -
