Jason Plato has lauded the impact of a differential change, which the former double British Touring Car champion says has 'transformed' his Subaru Levorg.

Plato enjoyed by far his strongest weekend of the 2017 campaign at Knockhill after snatching a dramatic 50th career BTCC pole position in qualifying on Saturday, which he then later converted into a 96th victory ahead of his Subaru team mate Ashley Sutton.

The 49-year old said his Team BMR outfit traced a small anomaly in the data following qualifying, which prompted his team to change the differential of his Subaru Levorg overnight prior to the opening race.

Plato subsequently went on to control the first race ahead of Sutton as the Subaru duo pulled away from the chasing BMWs of Colin Turkington and Rob Collard.

The Adrian Flux Subaru Racing driver said: "The fire has always been there, I just didn’t have the car to do it. We changed the differential last night [Saturday] and the car has transformed. I can make the car do what I want it to do, rather than arrive at the corner and go ‘there’s the understeer’.

"I’m really happy because it’s been a pretty tough year. It’s been tough to deal with.

"There was something wrong with the differential in the car. Whilst it measures the same, it’s not been working. It’s been pushing the car into the corner. They found a very small but difficult piece of information to find in the data."

Following the differential change, which has seemingly eradicated much of the front-end grip issues which has plagued much of his season, Plato now finally feels he has a car he can attack with for the rest of year.

Indeed, Plato was able to carry the ballast with little ill-effect during the following two races where he secured another a podium result with a second place finish in race two before ending the day with sixth in race three.

"I can race the car now. It does what I want it to do. I can’t drive a car which has got no front end. I need a car which turns," Plato continued."

"It wouldn’t rotate before. The tell-tale sign is that I’m going more and more rearwards on my brake bias. I’m starting to get into a happy place now.

"Whereas before I was a long way out on the numbers in brake bias from where I’ve been historically throughout my whole career, whether it be RWD or FWD. I’ve always had loads of rear bias and we couldn’t run it because we couldn’t get the thing to work. I can attack."

Plato has now moved back into the top-ten of the drivers' standings, but remains 154 points adrift of Turkington's championship lead.
