Buy or hire the Race Box if...
- you want one that is 22cm wider inside
- you want one that is 40cm (1.5ft) longer inside
Positioned for classic car owners and smaller motorsport teams who want their car fully enclosed and weatherproof but do not need the wider bed of the Race Sport or Race Transporter ranges. The narrower internal width suits a single classic or compact race car rather than a modern GT car.
