Installed on my 2003 SVTf ZX5. The build quality is excellent, the fit is good, the front lines are a bit short but they fit without any problems. I installed them on all 4 wheels and noticed a significant improvement in pedal feel. I bought these because one of my rear lines had collapsed causing the caliper to hang. I wouldn't say it's worth an upgrade alone, but if you need to replace calipers or lines it's definitely worth getting those in addition to the repair.
