SRO Motorsports Group has made sweeping Balance of Performance adjustments to the Pirelli GT4 America Sprint grid ahead of qualifying for this weekend’s season-opening races on the streets of St. Pete.
Issued in a bulletin to teams on Friday evening, six of the eight GT4 brands taking part in the event have been adjusted following the pair of practice sessions held earlier today.
The hardest hit for the second consecutive weekend is the Porsche 718 Cayman GT4 Clubsport, which has received an additional 10kg of minimum weight.
Other cars have been given weight breaks ahead of the pair of 50-minute single-driver races.
The KTM X-Bow GT4 has received a 20kg reduction, with 10kg less weight for the McLaren 570S GT4 and a 5kg break for both the BMW M4 GT4 and Panoz Avezzano GT.
The Audi R8 LMS GT4, meanwhile, has been handed a 5mm reduction in the minimum front ride height, although retains the same ride height in the rear.
No changes have been made to either the Chevrolet Camaro GT4.R or Ford Mustang GT4, which topped the time charts in Friday’s session by PF Racing’s Jade Buford.
It marks the second consecutive in-weekend BoP change for GT4 America, following a post-qualifying weight increase for the Porsche during last weekend’s round at Circuit of The Americas.
Teams will head directly into Saturday’s qualifying session, which begins at 9:15 a.m. ET, followed by Race 1 in the afternoon.
