I have the k-sport full coil over for a EG which is a bit softer 10f/8r than the DC specific.

They are stiff, but not overwhelmingly stiff. I have had them for a few years, although i don't daily drive the car. No signs of blown struts yet. The ride height is low, but not "slammed". I mainly use the car for spirited driving about once a month with approximately 360whp on tap.

If you to want make the drive to Lakeland to test them out before forking over a bunch of cash give me a call.
