Perhaps I could advise that I managed to locate a NOS front undertray Part Number 51 47 1 811 948 a while ago for my car and, knowing how much trouble I had in locating one, I decided to have produced replicas in black fibreglass using the stock item as a faithful pattern for others. I can knock these out at £150 a copy including stainless steel brackets and fixing screws plus post and packing (£15 for UK). I would imagine that most cars have been molested to some degree or other in the front apron department and, for this reason, I can either supply the undertray with the six standard "ears" and drillings on the leading edge or with a blank leading edge leaving the owner to do his own drillings in order to suit his particular car. The cut-outs for the radiator supports are in the right place in both cases, of course.
I know from experience that the original BMW component was not noted for its longevity. From memory, I have got through 3, possibly 4. of these undertrays in my time with the car as they became sodden with oil and water. In fact, it is very unusual these days to see a car still fitted with this undertray. You only have to observe the way the CSL bonnet swells and strains at the fixings to know that this factory-issue component is an essential piece of the car.
I do not have these in stock but they only take about 14 days to produce. Please PM me if you are interested or require further information.
