RX7 Tein lowering spring kit on 18"s?

[JohnP]

anyone got this setup?
 
reason i\'m asking is front arch looks close-ish on mine without lowering springs, but the arse annoys me.. as it has about an extra 20-30mm in the arch showing compared to the front..
 
so what i\'m asking really is.. will it rub like a beast if i drop it?
