Ah i spent hours under the car sanding everything down and wire brushing all of the components, then air blowing the crap away. All of the components are then covered in waxyol which lasts for bloody years!
Im not too fussed on the finish as its only ever me under my car. The bushes are all coming out in a week or so making way for polly ones, so any that need touching up will be done then. :-)
Im just surprised the price of oem disks were still that high. I imagined that as my mr2 parts had all fallen toyota would have done the same across the board, apparently not.
