I had not seen this thread before but I find it interesting because I had a couple of Mk III GT for 20 years or so.
I made some perspex cowls to go over the headlights, modelled on the items used by the works Spitfires that competed at Le Mans back in the 1960s. At normal road speeds they made little difference but at the speeds you are talking about they would be good.
I am not convinced of the need for a dorsal ridge. The Mk III at least was quite stable in a straight line at 100 MPH. Cornering stability is another matter, particularly on the Mk II. The rear wheels were prone to tuck under if you lifted off mid corner, causing dramatic oversteer. A friend with a Mk II fitted the lower rear wishbones from a Mk III and reported that this was a major improvement, so you might consider doing that, or something similar. Note that not all Mk IIIs had the rear lower wishones - later cars had a wider track instead.
What are your plans for the underside of the car? I made & fitted some panels that smoothed things out and I think helped. It is easy to fit this sort of thing because there is no shortage of places to fix things to the chassiss.
Another oddity with the GT6 is tyres. The Mk III at least was sensitive to tyres and did not always react as you would expect to a change of rubber. Indeed it was sometimes counter-intuitive; for example, increasing tyre pressures on some tyres gave better grip in the wet on sprint & hillclimb competitions. With other cars it was normal to drop the pressures. I have no idea how you would find out what modern tyres would suit the car best without some expensive experimentation.
Do keep the thread updated; I am interested to see your results.
