Some time ago, together with Stuart, we designed an extended stub axle for the Mk3 coupe and convertible. The Stub did away with the various metal brackets which are bolted to the radius arm. In time these brackets and their accompanying spacers rust or become loose. I got some extended stub axles turned. I only made six pairs and five of these stubs are fitted to various Mk3's. The new owners probably don't even know they have them. The idea was very successful and have been used in Mk3's since about 2009. with no reported problems. I've been asked on a number of occasions to reproduce these stub axles, but didn't have anyone to manufacture them, but now I do.
I have the first sample pair made and these have been improved with fillet radius's and stronger heat treated steel. If anyone is interested in a pair let me know. Price will depend on how many we order, but I'm anticipating some where in the region of £80 to £100 a pair, posted to a UK destination.
