Barrable (29) had a number of outings with the Kent-based team in last year’s VW Racing Cup.

A former Ireland FF1600 champion and Formula Ford Festival runner-up Barrable has also competed in the second tier of the World Rally Championship.
Thompson (17) contested last season’s Northern Irish FF1600 series and the previous season he had several outings in the Ginetta Junior Ireland series.
Meanwhile, Barrable hasn’t ruled out competing in this year’s Circuit of Ireland, he also reflected on last year.
“I suppose there is a bit of unfinished business. I shouldn’t have been anywhere near Craig (Breen), but I was until we slid off, but these things happen.
“I’m trying to get a car, I’ve been speaking with Martin Wilkinson of CA1 Sport to see what can happen.”

The following week Moffett will compete in the West Cork Rally, the second round of the Tarmac series.
His younger brother Josh is also on the entry list for the ten-stage event. Other entries are Mark Donnelly (Subaru WRC), Niall McCullagh (Mitsubishi), Enda McNulty (Subaru) and Michael Carbin (Mitsubishi).
