My corsa rear setup is almost as good a polo rears... not much in it.
I wouldn't advise Polo coilovers. Speaking from experience.
what downside did you find ?
Shorter the shock the better for you lowered crew. As the shock will be in its specified limit even whilst lowered I'm guessing the corsa b is shorter than corsa c?Corsa lowering shocks arn't too bad with the springs I'm using. Actually more comfy than corsa c rear shocks and cut micra springs...
Unnecessarily hard ride.
