Performance car drivers are being sought by Dunlop to take part in a national tyre test to discover what difference the choice of tyre makes to their car.

The company will provide tyres and tuition from a top Hi-Q British Touring Car Championship driver to transform the driving experience of six drivers from across the UK.

Interested drivers should visit the Dunlop stage at Goodwood during the Festival of Speed on July 4, 5 or 6.
