Mercedes-AMG has been hit with a pre-race Balance of Performance adjustment ahead of Saturday’s Kyalami 9 Hour, with changes impacting all four GT3 manufacturers in the Intercontinental GT Challenge powered by Pirelli round.

Released on Friday evening, SRO Motorsports Group confirmed a 10 kg increase in the Mercedes-AMG GT3 Evo’s minimum weight, which brings the car up to 1350 kg for the race.

It comes in addition to a 5 kg addition that was made on Thursday afternoon in between the second test session and Free Practice.

The German manufacturer has topped all but one timed session at Kyalami so far this weekend, with GruppeM Racing scoring pole by more than three-tenths of a second.

Other changes since the original pre-event BoP include 5 kg weight breaks for both the BMW M4 GT3 and Porsche 911 GT3 R, along with a increase in turbo boost pressures for the BMW.

Additionally, the Audi R8 LMS GT3 Evo II was given a 1 mm larger air restrictor, which along with the BMW and Porsche adjustments, were communicated to teams prior to the start of Free Practice and were thus in place for qualifying.
