Charlie Eastwood and Chris Smiley are more used to racing on tracks like Silverstone and Brands Hatch but tomorrow they will be taking to the hills - literally.
They are both making guest appearances at Cultra hillclimb, one of the oldest events in the Ulster motorsport calendar.
Eastwood, fresh from another podium finish in the GB Porsche Carrera Cup at Oulton Park last weekend, will drive a road-going Porsche and Smiley, who was racing against Colin Turkington in the British Touring Car Championship at the Cheshire track, will be on board a Lexus GSF as they perform demonstration runs at an occasion which is part motoring competition and part garden party.
Run by the Thoroughbred Sports Car Club in recent years it has adopted a theme and this time it is Triple M, a celebration of the pre-War MG Midgets, Magnettes and Magnas.
Taking part will be a little single-seater special which was built by Alec Issigonis long before he earned world-wide fame as the designer of the Mini.
The Transport Museum will also be unveiling their recently restored Berkeley sports car which will be on display at Cultra Manor during the event alongside the touring MGs.
The Cultra climb also has a strong competitive element and is also part of the Miller's Oil Northern Ireland championship, currently led by Chris Houston.
