I have a set of Gen 2 factory sport suspension springs in excellent condition. They were on my JCW Coupe for about 2.5 months before I lowered it. Asking $100 plus shipping to the lower 48.
Buy these springs and I'll tell ya! Kidding of course. I went with the NM Engineering RS Alpha springs. They've proven to be a great choice if you don't mind a stiffer ride and having to be a bit more diligent in what you drive over.
