Remember Skunk2 Has 2 versions of full coilover the Spec-S and Spec-C the K-sport BASE model is equal to the TOP model from Skunk-2 and comes with a 1 year no questions asked warranty. so apples to apples you get a bit more with the K-sport

the Pro-S is non damping and non-length adjustable. I personally have sold 10 sets of K-sport running around tampa and none have failed since I started selling them 2 years ago.

I rebuild coil overs and have torn apart enough K-sports to stand behind their quality. Not trying to sell you, since there are sever good brands on the market. but Both myself and Loren have had great experiences with them.
