The Intelligent Money British GT Championship’s 2021 entry process officially opened earlier today ahead of the first round at Oulton Park on Easter Bank Holiday Weekend (April 3 & 5).

GT3, GT4 and GTC cars remain eligible for the UK’s biggest GT championship, which this year welcomes the revived Silver-Am class to its senior ranks alongside Pro-Am. Variables within the FIA’s grading criteria mean not all Silver drivers automatically qualify for British GT’s Silver-Am classification. Instead, the Silver element will typically comprise promising but less experienced young drivers, GT4 graduates or those likely to contribute some budget when paired with a Bronze-graded amateur.

Several existing teams with confirmed driver crews have already announced their plans while more are expected to do so in the coming weeks.

The seven-event, nine-round calendar is now also confirmed with #DoningtonDecider taking place as previously provisionally scheduled on September 11/12. Dedicated pre-event test sessions before every race weekend other than Spa will also provide a more cost-effective opportunity to prepare.

However, the traditional pre-season Media Day will not go ahead.

British GT’s regular support series roster also returns in 2021, albeit with a few surprises in store. The BRDC British F3 Championship co-headlines all seven weekends, the Ginetta GT Academy and Protyre Motorsport Ginetta GT5 Challenge feature at five of them, Porsche Sprint Challenge GB’s second season includes three outings once again (Brands Hatch, Silverstone 500 and #DoningtonDecider), and Caterham will also feature.

But it’s the return of GT2 machinery to British GT weekends that’s bound to excite sportscar fans past and present. Domestically, the class became obsolete at the end of 2006 but now returns courtesy of SRO Motorsports Group’s new GT2 European Series, which stages two separate 50-minute races during British GT’s Silverstone and Spa-Francorchamps weekends. The championship announced before Christmas that entries spanning Audi, KTM and Porsche are already confirmed.

Meanwhile, the rebranded GT Rebellion Series for current and older GT3 cars will join British GT’s grid at the three-hour Silverstone 500.
