wow maybe ebay coilovers are bouncy. but if you got yourself a decent set of coilovers like tein or buddy club, it would likely be smoother than what you have now.. however, if you're looking to save yourself some money i was very satisfied with my skunk 2 coilovers. i wouldn't cut my aftermarket springs because when i bought my civic it was riding on some neuspeed springs that had been cut and it wasn't the best ride. skunk 2 coilovers fixed my problem.
