I think trying to make it 4wd will over complicate and over budget it, it isn't neccisary unless you want an exact replica.
My 5 sits at 1000kgs and with 235 road tyres I don't get any wheelspin in the gears (apart from 1st) with 400bhp.
And I have only set the car up at home myself.
I expect once a pro does it I won't get spin in 1st, and that's with an open diff.

With a 200, it will b a wider chassis, wider tyres, properly setup, 4wd isn't needed but obviously will make it a better replica.
