I plan on getting my KW coilovers either by the end of this month or the beginning of the next, So I was wondering how everyone has been running them? How to prelong them on these crappy streets and what settings people have been using on the track. I dont want to leave them too tight on the street because its too bumpy and I dont want them to blow early. How long has anyone used them before they have needed refilling?
