Keep it real

 Keep it real

'We choose mainly rear-wheel drive cars, as they oversteer more and look more dramatic when they move around. They need a locking rear differential so both wheels spin together. It makes for more dramatic slides - and we always disable the traction and stability control. We do the cars up in our own workshop.

'For cars central to the plot we sometime build a hero car and then some stunt versions too. All will have roll cages in, beefed-up engines and we remove the airbags. There's no point in disabling them; with what we do to them, the airbags will go off anyway.'
