Okay, I think I misunderstood "after crossing the finish line" of the final…
Martin told me in 1985 the Xtrac was still in 50:50 when he tried his usual donuts, but needed 28:72 to do them. The tarmac at the Estering was very rough by then. However, for the next race Martin’s Finnish mechanic Jorma "Jokke" Hannula had fixed a tiny wheel on each corner of the Mk3 roof.
