as it is I don't have any rubbing issues with the 25mm drop. Had 5 adults in over speed bumps and all good! Don't think I would drop it any more than 25mm because it looks good as it is!
pointless in your eyes maybe. But I didn't spend the cash on getting them, so I'm not assed! Plus when I put my standard alloys on in winter it gives me the option to drop it then.
