You might be sitting a bit high in the back after installing those. The rear doesn't sit lower from the factory, it sags over time. Buying 3" lift springs should give you 3" over factory. Unless you have the front lifted already and I'm just dumb. <img src="/forums/images/graemlins/cheers.gif" alt="" />
Where did you get the springs from?

I'm between toyotas right now... 3rd Gen 4-runner soon.
