A battle which has raged all season concludes on Saturday at Kirkistown with two drivers in contention to be crowned the 2016 Northern Ireland Formula Ford Champion.
Former footballer Noel Robinson seemed to be on a clean run to taking the prize but at the July meeting two non finishes and arch rival Alan Davidson powered to the top of the points table.
Davidson who drives a locally built Mondiale goes into the two final rounds with a slender nine point adavantage and there are 44 points available, with points for pole position and fastest laps, so a major effort is expected from both drivers.
There will be more single seater action from the mighty BOSS Ireland series; Formula Sheane and Formula Vee pay a very welcome return to the fast County Down circuit.
Robinson comes to his home circuit leading the BOSS Ireland Championship, so for him he will be the busiest driver on track tomorrow.
He will aim to gain as many points as possible before the final meeting at Mondello Park next month where the BOSS Ireland drivers will contest the coveted Leinster Trophy.
Tin top fans will be well catered for with the Kirkistown Saloons, the budget class of saloon racing Ford Zetec and the powerful SEAT Supercup Ireland series.
Only Rod McGovern has raced a Supercopa at this circuit.
However he will face a strong challenge from former Irish Touring Car Champion and leading showjumper Erik Holstein, Niall Quinn and Rob Butler.
Roadsports and HRCA Historics add flavour to a very varied programme.
Jonny Forsythe has stamped his authority on the Zetecs so far this season, but he too will face stiff competition while expect the Kirkistown Saloon entry to include BMWs, Hondas and SEATs.
Roadsports and Jim Larkham with his Radical has stamped his authority on this class, but a number of Crossles could just put paid to that ambition.
