Well, step one is to purchase an original road going version
of the car you intend to base your racecar on. So, one trip to the scrapyard
later and we have a bog standard Vauxhall Tigra. This will form the basis
of ‘the plug’

What we now need to do is make this standard Tigra into exactly
the same shape we will eventually want our racecar to be. This is done
in a variety of ways, but our preferred method is to cut large blocks
of dense foam into blocks which we then stick to the road car to map out
our basic shape. This foam is then covered in filler, lots and lots of
filler! (30 gallons to be precise in our case)
