front and rear 5100s + tax and free shipping comes out to about $550 US dollars or $680 for anyone in Canada
150k on the factory xreas now... so starting to think about what's next
here's a link below. does anyone know why the rear shock says "excludes x-reas" . I would assume that simply means it cannot function with the xreas system. I'd pull the entire xreas out anyway, lines, brackets and all, and use stock front coils
