depends how the makers list them.but usually they ignore the lowered models so on yours it would most likely be 60mm where on a sporting it would be 50mm if its already lowered 10mm from the factory
might cause some knocking but a a std cinq is 20mm higher anyway so it would prob go about 80mm+ there is some springs for the sporting that go 80mm but then you need shortened uprated shocks.
so it will still probably sit 60mm lower. thats way too much on my car. the wheels scrub already four up. i think i need to get some lower profile tyres first. im running 185/55/14 at the moment
It'll lower either 70 and 80mm (not sure if difference between S/SX and sporting is 10mm or 20mm) - way too low for everyday road use IMO (though arc'll say it'll be just right )
