So far so good, only had them less than a week. Ride is good, they are an A/T tire and will be noisier than stock, but not terrible. Hasn't rained yet, so no feed back on that.
Bilsteins are a good way to go. The shop who did my level said they would recommend them over any spacer leveling kit. I went against that advice, primarily due to price. I got a deal that I couldn't pass up. Im happy with my readylift 2.25 with UCAs.
