cant see them but i assume they are either rs or rm's shop around because prices vary but i think for 2" outers your looking at about ?80 a rim.
i re-furbed mine and they were quite time consuming but not too difficult. i'd do them again if i had to!!! if you were to pay to have them done you normally pay about ?65 a wheel for a re-build....it all adds up! thats why i did mine myself!
