Dan and Peter at Suspension Supplies Ltd (
www.suspensionsupplies.co.uk) are the people to talk to - they did the dev work on the original suspension using Suplex units - it also turns out that some of the work also involved Black Arts Designs (
www.blackartdesigns.com)....why do we know this - we had a broken rod in one of our units - in theory it should have been rebuildable but it turned out that the units on our car were part of a batch of non-rebuildable prototypes made by BAD - luckily BAD had a one-off spare lying in their attic....SSL put us in touch with BAD to make it all happen...great service by all involved.....Incidently our bump stops still seem OK so sunlight or higher ambient temp may be a problem
