Jaguar, Porsche, Lancia, Mercedes-Benz and Nissan (below) are all due to vie for honours, but there are some interesting newcomers, too.
Paul Stubber is travelling from Australia with his Chevrolet-engined Veskanda. One of only two examples built, this is the rarest car on the grid and was campaigned in the 1985-'87 Australian Sportscar series by John Bowe.
Other newcomers are Adrian Watt in his Argo JM19 and Trevor Knight who will be driving the Damax Spice SE88.
The most eye-catching livery is likely to be that of Henrik Lindberg’s green and white Tic Tac Porsche 962 (above), and the iconic colour schemes of the Martini Lancia LC2 (main image) and Richard Eyre's Jaguar XJR16 (below) will strike a chord with many racing fans.
The race will be split into two classes – C1 and C2 – for the most high-powered and slightly smaller engined Group C cars.
Qualifying will be from 12.40-13.20 on Saturday 5 May and the hour-long race proper kicks off at 15.45 on the Sunday.
Day tickets cost £18 in advance (£25 on the gate) and weekend tickets £30 in advance (£40 on the gate). Children aged 15 and under are admitted free.
