Wilson has won five out of six Supersport races this season
Boston's Ben Wilson extended his lead in the British Supersport Championship with a double victory at Croft.
The Gearlink Kawasaki rider, 29, has won five races out of six and has a 39-point series lead after three rounds.
Woodhall Spa's Steve Plater claimed two podium finishes for Padgetts Honda, finishing third and second.
In superbikes Shane Byrne of Louth's HM Plant Honda team took victory in race two while Lincoln's Alex Lowes was an impressive fifth in the opener.
Byrne, who retired from race one with a blown engine while in the lead, dominated the second race to move to the top of the overall standings.
But his team-mate defending champion Ryuichi Kiyonari had a torrid weekend, picking up a solitary point for 15th in race two.
Run in changeable conditions on a drying track, the opening race saw Jon Kirkham take his maiden BSB win, with Lowes coming home a best-ever fifth on the WFR Honda before finishing 11th in race two to take BSB Evo class honours in both races.
Louth's Peter Hickman, on the Tyco Honda, also enjoyed his best BSB result with seventh in the first race, which he followed up with ninth in race two.
