Paul Miller Racing and Wright Motorsports have become the latest high-profile additions for next month’s Michelin SportsCar Encore at Sebring International Raceway.

The two teams join the previously confirmed efforts from Riley Motorsports and Black Swan Racing, which will see an expected four-car entry for GT3 machinery.

While Paul Miller has yet to confirm its 2020 program with its Lamborghini Huracan GT3 Evo, Wright is expected to field two Porsche 911 GT3 Rs, anchored by Silver-rated Anthony Imperato and Bronze-rated Ryan Hardwick.

GT3 cars will be permitted for the first time in the four-hour race, after IMSA elected to disallow the class in the inaugural running due to several teams’ requests to run Evo-spec machinery which were not yet homologated.

Drivers beyond Tim Pappas in the No. 540 Black Swan Racing Porsche, have yet to be announced.

Among the LMP3 teams already confirmed include 2018 race winners ANSA Motorsports, Forty7 Motorsports and Performance Tech Motorsports, with Riley, Turner Motorsport and newly crowned Michelin Pilot Challenge GS champions CarBahn with Peregrine Racing set to run GT4 machinery.

A full entry list will be published on Monday following the extension of entries, which is believed to have been due to a lower-than-expected initial turnout.

A total of $100,000 in cash and awards will be up for grabs in the Nov. 10 race, including $7,500 in Michelin tire credit to be applied towards 2020 IMSA events for each of the four class-winning teams.
