I ordered some. Plan to install today. I would like to know who told you this and if it is an individual experience or if they are an installer/vendor who has seen systemic issues?

Put mine on this weekend. Went in easy enough but had to trim 1/4 off each side of the front Z51/C6Z sway bar as it was touching the spring.

I got QA1's front and rear on C5 using 550 springs. We corner weighted the car after the install and the car is right at .7" lower than stock ride height. The car handles great and tracks and turns best it ever did. I think GM recommends no lower than .75" of lowering for correct camber gain and minimizing oversteer if car doen't have acceptable rake.
No leqak issues on any of mine and I had on two cars before with no problems. My installer shop told me he had heard old president and cob had returned and fired the former head guy who was running the company into the ground.
