Silvester was in the thick of the Hot Hatch action in Wales although ultimately only won one of the three contests in his Honda Civic.
However, he also topped the Mk2 class in both of the Toyota MR2 bouts to charge 13 places up the leaderboard, making him this week's highest-ranked improver.
But Silvester was not the highest-placed driver to increase their 2023 win tally as James Clarke added to his Clubmans Sports Prototype total at Brands Hatch, but remains third in the table.
The presence of Mark Charteris meant it was just a class victory in the opener for the series dominator but his Phantom then suffered a broken stub axle that put him out while leading the second race.
Clarke therefore moves to 15 wins for the year, one behind table-topper Ryan McLeish, who usurped Freddie Slater at the head of the rankings the previous week.
Further back in the top 10, Junior Saloons ace Daire Flock picked up another triumph in the first Silverstone encounter but was unable to deny the charging Cameron Pratt-Thompson in the other two contests.
Nevertheless, the sole success still moves him from 11th to ninth as he joins a small flock of drivers on 12 wins.
