They are 60mm 'Driver' springs for a carbed model but ive since modified the top mounts to make them 20mm lower on front.
I was under impression that 16v springs were shorter than carb springs, so if theory 60mm lowering springs for a 16v put onto a carb car would only lower the car 40-45mm depending how much lower 16v are to carb models? does that make sense?

Just been outside and measured my car,
the front spoiler is 3" off floor
the lowest point of front arch is approx 21" from floor
the lowest point of rear arch is 21.5" from floor
the Sideskirts are 4.5" from floor.
All this is measured with measuring tape but not 100% cause although floor looks level it prob isnt.
