The fibreglass Special Tuning spoiler originally produced
by BL under part number STR 0189. It is available at most MG stockists, although
they are all copies now.
It was designed with wind tunnel assistance and reduced the standard MGB
CD factor from 0.42 to 0.38. I first fitted one to my car in 1976 and found
it to be very effective at reducing the effect of crosswinds on an open road
or motorway. Can't say that it added any performance though, and after I
went V8 I still found that at 130 plus mph at Bruntingthorpe test track,
the front still lifted to make the steering 'quite light'!!
