Yeah, checked out their website and they only make springs for 3rd Gen Mazda 3s....Never liked H&R, too stiff. Not the best pairing for bilstein. Not sure what other options there are but Corksport or tanabe would be my first picks. Shame that Eibach doesn’t make springs for the third gen because they go perfectly with Bilsteins. I’ve tried Eibachs on a Scion FRS before and loved em.
