You could add Standard Suspension (STD) on your list.
They are better quality than Ksport, are monotubes, body-adj. so you don't loose any travel, have a nice gradation system so you don't have to guess the ride height, are one-way adjustable and most of all they are the ONLY COILOVERS WITH FRONT CAMBER PLATES for our cars. You can adjust the damping from outside the shock at the rear, so no need to cut the trunk inner plastic trims. They have a warranty too.
Finally they are really competitive here in Canada in drift, track and rally.

I got them since about a month and trust me they are a quality product, and the price is competitive.
