im not sure of the drop, but it is quite low, front splitter is now cracked and scrapped bad on the bottom. I had it lower, but the underbody scrapped on speed bumps, so raised it like 10-20mm and now i can go over speed bumps fine, etc. Its only bad when you go fast down a badly tarmaced road and the suspension bounces and then the splitter hits the floor cause it is soo bouncy!
I run 15" alloys with 195/45/15 no rubbing in the arches ever, even with a full car and luggage in the boot.
I do know that the front splitter is about 8-9cm off the ground. I think i found a good height tbh. No rubbing, minimal scrapping and looks low

problem with 16's is that you cant really get the stretched look as i cant find any tyres that are thin enough, samllest is 195. my azevs that are sat in the garage have 205's on and look v bulgy and they are 7J.
