A friend of mine is looking to buy some ball joints to make up some sets of droplinks. Does anyone know of a reasonably-priced, UK-based supplier of decent quality ball joints for road use?
There are lots of different designs and materials, but if it's just for anti-roll bar drop links it wouldn't be very demanding. Rally / Marine Design have a wide range which they claim are manufactured especially for them, Aurora and National Rod Ends also do a wide range.
