Yep, everyone has different tolerances for tire wear and ride quality.

I rode on H&R sports for 2.5 years with no camber correction and I was able to get 25K miles out of some Kumho 712s.

I also had the H&R sports with the stock shocks for 2 years and they kept the ride dampened pretty well. No blowns shocks. Granted the Koni's I have now are much better and offer much more performance and I would still recommend you swap to performance shocks when using sport springs, but the stock shocks really weren't as bad as some people make them out to be.
