Found something else in the mag. In the Archive section ( letters page ), an article from Autocar ( Sinclair on show section ) 26th December 1984 says :

Stability has been a key factor in the design brief and he says that Lotus staff have driven C5's on two wheels over to an angle of 45 degrees without it falling over.
