That scared me when I first saw it (and still does!), especially because Tiff is quite tall for a racing driver and was not wearing a helmet.
Of course, you rarely generate the same forces on the public road that are possible on a race circuit, but even so...
Also, even a four-wheeler can flip when coming back onto a high-grip surface from wet grass at the wrong angle.
I am still running in my M3W and often find that I have to back off or change up just at the point where it might be possible to go neutral or even into oversteer with a heavy application of throttle - and I am not even sure if it is possible.
As most people on here will understand, if you have too much grip in a three-wheeler, stability can be reduced, perhaps to a dangerous extent.
It is interesting that Chris Harris, in his video last year, was able to oversteer the 3 Wheeler impressively on the public road. Chris is a very fast and highly competent driver, like Tiff, but I wonder if that was because the car was on the early setup, with Suplex dampers (I do not know if it was or not).
In any case, there is not a wide choice of front tyre, as far as I am aware. Perhaps more power is the answer - or reduced grip of the rear tyre!
