Clarke and his Phantom PR22 spooked his opposition with a stunning display at the Welsh circuit to win all four races and set a new series lap record at the venue in the process.
Added to three wins he had already snared earlier in the season, these latest triumphs have sent Clarke rising up 26 places in the winners' table.
He has reduced Mazda MX-5 ace Aidan Hills' advantage at the top to two victories and Clarke is only the second driver to score seven or more wins so far this year.
But there are a host of other contenders creeping up on Hills, including Radical Cup UK star James Lay.
He impressively won all three races as the category made its first appearance on the British Touring Car support bill at Snetterton, meaning the reigning SR3 champion jumps 30 positions and into fourth.
Another driver to enjoy a successful Snetterton was local racer Dan Zelos, who claimed two more Mini Challenge victories to take his current total to five and enable him to rise 31 spots to seventh.
