Yeah the mounts are fine but the standard mk4 cups looks sh!te when fitted, An people using the polo cups lasts a few weeks/months and they look wrecked because the rubber rips apart and exposes the metal.
I think its down to psi tuning to ensure the kit works well and lasts, even if they have to make a custom cup to make it work.
I was up for this but waited until people tried them but I think I will stay away and keep to OEM for now.
