Both of my Rear springs had snapped on my 10 year old Brera 3.2 Q4, the ProKit was already cheaper than replacing with OEM springs and I reckoned after 10 years the dampeners might as well be replaced at the same time before they started to leak. This kit does not disappoint, not only is body roll kept extremely tight but this kit is significantly more comfortable than the stock suspension setup even with lower arm and adjustable upper arm polybushes! I can highly recommend the Sportiva kit to any and all as an all round setup 5*
