British Formula Ford race winner Max Marshall will make his Formula 3 debut with Double R at Thruxton next weekend, replacing European F3-bound Andy Chang.
Macanese driver Chang, who is currently fourth in the British F3 standings, is to replace Hector Hurst in West-Tec's European F3 line-up from the Nurburgring event, which clashes with Thruxton.
Chang will also contest the Hockenheim season finale, but has to miss the other remaining European series round at Imola in October due to a clash with a major karting event in Macau.
Marshall formerly worked as a mechanic with Double R. The 19-year-old is third in the FFord standings following his maiden victory at Snetterton last weekend.
Double R team boss Anthony Hieatt said: "Thruxton is an incredibly challenging track for your debut in an F3 car but we know Max is more than up to the job and capable of a strong showing.
"He had a fantastic run at Snetterton in Formula Ford last weekend. It was great to see him take his first win as we've known Max and his family a long time.
"Although next weekend will be tough, he's definitely got the skills to make a lasting impression."
