Airwaves Yamaha rider Leon Camier and Worx Crescent Suzuki star Sylvain Guintoli have established themselves as the early front-runners and will be looking to stamp their authority over the rest of the field.
Having grabbed three wins out of the four races, former British Supersport champion Camier is the firm favourite to take the spoils.
But ex-MotoGP star Guintoli has emerged as a serious title contender since his winter switch to Superbikes and winning at Brands Hatch.
After a sensational double win at Oulton Park in round two, Camier has taken the initiative and Guintoli will no doubt be desperate to regain control over the series at a circuit he knows well from his time in MotoGP.
"I'm looking forward to racing at Donington. It's the first track that I've been to this season that I have previous racing experience at, due to my time in MotoGP.
"I do like Donington Park as I've had some good races there. I think experience will play a part in deciding where the race will be won or lost.
"I know the circuit very well."
And there is another reason Donington holds fond memories for Guintoli:
"I met my wife there in 2003, so I'd have to say that this is my strongest memory of the circuit."
"I really like Donington Park. It's a technically challenging circuit. I think it will be won in the last few corners, from the chicane down to Melbourne Hairpin and then the last corner.
