yeah mate, Ive lowered it by about 30 mm but the Cupra R starts off lower than the others so it doesn't really
help you. Sorry mate.
I do get some rubbing with passengers in the back, but I have 20mm spacers on the rear so it's no wonder! I'm going to get 215s on the rear for my next tyres so that should eliminate that issue.
Good luck with it mate.
