get brembo,alcon or AP and even wilwood over the harrops.harrops are way to much money for what they are. harrop charge way way to much for most things they make,cause its made here and harrop is a rip off. the only thing that they do a good price on that i have found is custom studs i.e head and mains. i dont know of any of the race teams using harrop calipers anymore,most are using brembo 12 spoters.
