yes or no on a vRS?

I go fishing and trips down to reservoirs and venues are often on flattened hardcore tracks....just wondering if on the rear it may save my back bumper a bit?

are they available on the mk2 and a rough cost if anybody knows

are they easy to fit...I assume they just screw to the wheel liner?

Have front ones fitted to my mkII vRS to stop the stone chips on the sills & door bottoms, however I was told the rear ones don't match the profile of the vRS rear bumper, without a "bit of cutting"! Didn't fancy being the first one to try it out, so will wait until I se anotherone with them on! Think the front ones were £20

I've heard from 2 seperate people they won't be manufacturing ones to fit the Mk2, btw one of the lads had his dealer mould a set of standard ones by heating and putting them on.
