The GoldLines are Pro-rate...I have them on my ride. No complaints about ride, although it could use more dampening in the new (lowered) range.

EZ4U... OEM struts, any vehicle-any make, will only perform 'optimally' for upwards of 15K miles, depending on habits (e.g. towing, etc...). Most people exceed this limit with little to no notice of lost performance. Just the oposite is true, however.
I'm not suggesting everyone always change your suspension every 15K, just that they're going to (technically) be 'worn' by 15K- so why wait to lower??? Just my opinion...
