Mine is a daily drive, and lowered... Which you know as I bought my springs from you (unless I'm going a bit senile :? )
It's fine, especially on motorways - it's speed bumps that are the issue, which affects everyone. The ride is actually better on smoother roads because the springs are designed to increase resistance the harder they are pushed, I believe, unlike OEM that are a constant resistance.
Of course I may be totally wrong - exdos is your man for suspension science - but the ride in my car got better when driving normally.
