Change to the DTM BoP: BMW and Ferrari slowed down, more power for Ford!

(Motorsport-Total.com) - Unusually early change to the Balance of Performance (BoP) on Friday evening in Zandvoort: This is because qualifying for Sunday was brought forward due to the Le Mans test overlap and has already taken place - and the next qualifying session is already scheduled for Saturday morning ( all information on TV times, stream, etc. ).

Four vehicles are affected: The BMW M4 GT3 Evo, in which Rene Rast set a pole record and is also in third place thanks to Marco Wittmann, will have ten kilograms of ballast added to the car on Saturday. The boost pressure will remain the same, but the minimum rear wing angle will be increased by one degree.

This makes sense, as the BMW was always the fastest car in the top speed measurement on Friday and overtook one rival after another in the race last year.

Rast and Aitken: Success ballast is also added

In Saturday's race, Rast, after finishing second at the Lausitzring, will also have ten kilograms of ballast added to his car, making the task even more difficult. Jack Aitken's Ferrari, which secured a front-row starting position in qualifying for Sunday, will also have ballast added to it.

The Emil Frey team has to load five kilograms into the Ferrari 296 GT3. In Saturday's race, Aitken will also have to cope with 20 kilograms of ballast.

This is how the Ford Mustang should be faster on the straights

An interesting change is being made to the Ford Mustang: After Arjun Maini's 16th place, five kilograms of ballast are being loaded, but in return the US-American racing car gets a restrictor that is one millimeter larger, thus more engine power.

Since the start of the season, the restrictor's diameter has already been increased by two millimeters, resulting in more engine power. This decision also makes sense, because the Mustang, which is notoriously difficult in the corners, was surprisingly not the fastest car on the straights at Zandvoort on Friday, instead being towards the back.

Speaking of which: The Porsche, which had received a 3.5 millimeter larger restrictor before the weekend , is also in the middle of the field in the top speed measurement.

The BoP for the Aston Martin has also been changed: The Comtoyou team, which set the fastest time with Gilles Magnus at the Zandvoort test two and a half weeks ago, can look forward to slightly more boost pressure in the mid-range. Magnus finished 20th in qualifying for Sunday.
