I purchased these for my Core just to see what they would be like. My opinion is the ride quality on average roads is the same but compression is much stiffer over big bumps or potholes. Basically, if you're planning on tracking your GR (which I never was) and don't want to go nuts with a suspension kit then here's your upgrade. Otherwise, for a car that's just going to see daily use then maybe not. Anyway, these have less than 100 miles on them, were purchased directly from a dealer and will come with the original receipt. The struts have some marks on the paint from shipping but are otherwise perfect. These are inverted heavy duty struts similar to what Subaru used on the STI. Made by KYB. Price includes shipping.
