No rubbing at all on the current setup. Once I install the spacers, I'll have to get the fenders rolled for clearance so that I continue to have no issues.

 

How's the ride comfort vs stock? Just curious.

 

ProKit is much better than early Z stock set up. Marginally better ride than later models, which already have a pretty decent ride with the 04.5+ revised springs/shocks.

Sportline.... Compared to stock, ride is firmer but "better" in a controlled way. It's all in the Bilstein shocks. You put a set of Koni's in with the Sportlines and ride quality DOES go down further but great control.

Bottom line: I personally prefer either to stock and between the two, prefer ProKit because I don't need gonzo lowering.
