Had mine on for about a year now and they have been ok, apart from the fact I can't raise the back any higher without compressing the helper spring so much the back end becomes a bungee over bumps. Taking the helper out will make the ride lower so thats not really a solution. Its like the adjustable range for the coils are 70mm to 120mm . Having just got some et 18 wheels I need the back end a touch higher so I can sort out the arches etc and not scrape my pricey exhaust on every speed bump!
Any tips or help would be great.
Cheers
