Too simple for the money, difficult installation, do not fit...
Works for now, but air connections seems not a heavy quality to hold air for a long term, but hope to be wrong... The installation was a total pain in Mazda 5 2012 at least, inclusive releasing the struts, because the air bags are biggers than the internal wide of the springs, causing to force the air bags fitment in a twisted complicated way... Sorry, but I would recommend to look for another more specialized solution for the Mazda 5 2012 weak rear suspension.
THE STRUTS DO NOT LEVEL. THE SPRING HITS THE A ARM WENEVER I GO OVER A MEDIUM BUMP, WHENEVER I GO OVER A SPEEDBUMP OR A SMALL HOLE THE SUSPENSION UNLOADS WITH A HARD THUD AS IF THE SUSPENSION HAS NO TRAVELOR IS OVER EXTENDED tHE FRONT RAKE IS ABOUT 1,5" TO 2" HIGHER THAN THE BACK. BECAUSE OF MY WORK I TRAVEL OVER MILD TO MODERATE DIRT ROADS THIS SUSPENSION DOES NOT WORK FOR ME.
