There have been a number of updates made to the Avon Tyres British GT Championship entry list for this weekend’s double-header at Snetterton.

The entry issued on Monday included two TBAs, which have both now been filled. Aston Martin Racing factory driver Alex MacDowall has been confirmed as Ahmad Al Harthy’s team-mate in the #2 Oman Racing Team V12 Vantage, while Mike Hart once again partners Chris Webster aboard the #62 Academy Motorsport Aston Martin GT4 Challenge.

Elsewhere, there have also been two changes to originally announced GT4 driver pairings. AmDTuning.com boss Shaun Hollamby now partners Graham Coomes in the all-Am #49 Porsche 911, and Century Motorsport’s Aleksander Schjerpen is joined by Sweden’s Fredrik Blomstedt aboard the Silver Cup-entered Ginetta G55.

Both of Sunday’s one-hour races will be shown live on Motors TV (Freeview 71 & 240, Sky 447 and Virgin Media 545). Coverage begins at 12:35 and 16:20 BST.
