'How Valid is the Concept of Multi-Discipline Competition cars?'

[Jack95griffiths]

Those bare bones are only likely to be the unibody, roll cage, the safety gear etc.
Things like springs, shocks, tyres, are going to be totally different. Never mind the fact that the torque curves required for track racing are different to that on loose surfaces.

At some point, you're talking about something akin to The Ship of Theseus.

Oh, I think we've been on the wrong page then - in essence that's the only way this will work. When I say multi-purpose competition cars, the physical car and whatever is still useful remains the same. To the untrained eye they'll be different cars.

Ken Block basically did this, used the same car (chassis) for Gymkhana, Rally Cross and Rally's and had to essentially rebuild the car each time changing components like suspension, brakes, maps for each discipline, but this worked out better than campaigning 3 different cars for him.
