West was in stunning form in Wiltshire, winning the two Kumho BMW contests as well as both Classic Thunder races in his E46 M3 - despite some hard-fought battles with rivals.
Those successes have not only allowed West to shoot up 10 places in Autosport's rankings, but have also taken West's tally to nine for the year.
This moves him to within two wins of table-topper Freddie Slater, although the Ginetta Junior dominator is due to be in action again this weekend.
Another driver on the move is Lucas Romanek, who scored his sixth and seventh Formula Ford 1600 wins of 2023.
His latest triumphs came over a very thin United FF1600 field at Snetterton, wins that enable Romanek to climb 13 spots into seventh on the latest leaderboard.
The only other change inside the top 10 comes courtesy of Sports 2000 star Michael Gibbins.
The MCR S2n pilot was another driver to enjoy a fruitful Castle Combe visit as he topped both races, enabling him to rise from 31st to joint 10th.
A little further back, a trio of Irish drivers have also made progress up the winners' table after succeeding at Mondello Park.
Peter Barrable and Michael Cullen are tied in 14th place having both added to their totals at the weekend - Barrable scoring two Legends wins, while Cullen took the honours four times, heading the field in both Stryker and Fiesta ST bouts.
That has propelled Cullen up the leaderboard from outside the top 50, while Barrable rises from 49th.
This duo is one place above Jackie Cochrane, who was another double Mondello winner to leap up from joint 46th to 16th.
Behind them, in 17th, is Dan Silvester after he was also a quadruple winner, this time across both Hot Hatch and Toyota MR2s at Mallory Park.

All car races in UK and Ireland are included except qualification/repechage, consolation and handicap races. No races in other countries.
Class wins are only counted when there are at least six starters in the class. Only classes divided by car characteristics are included. Classes divided by driver characteristics such as ability, professional status, age, experience (for example rookie or Pro-Am classes) are not included.
Where there is a tie, overall wins take precedence. Where there is still a tie, average grid size for a driver’s wins determines the order.
