you get what you pay for. Spacers are the cheapest way to go, but the worst option
their ride sucks, and they introduce the risk of damaging shocks because they extend the shock length without adding any travel
if you're not going to offroad, and you're going purely for looks; and there's no way to save up more money, they'll be fine.
there's lots of people running spacers and are happy with them. However in terms of lift quality, there's a reason coilovers are $1400, to these spacers $250
