I’m (almost) starting to feel a little sorry for the Porsches as things just aren’t going their way. The defending GTLM champions have yet to win a race this season as lady luck has shown them no mercy in 2020. And to make matters worse, IMSA is targeting the 911 RSEs for the second race in a row with an additional 20kg of ballast according to the technical memo released ahead of the TireRack Grand Prix at Road America next Saturday.

Porsche was the only manufacturer in GTLM to see changes to the Balance of Performance this week. The additional 20kg brings up the minimum weight of the 911s to 1320kg. The Corvettes are racing at 1280kg while BMW remains the lightest in class at 1220kg.

The No.3 Corvette C8.R with drivers Antonio Garcia and Jordan Taylor are currently leading the GTLM standings with 165 points followed by Porsche 912 drivers Earl Bamber and Laurens Vanthoor with 146 points. The No. 4 Corvette’s Oliver Gavin and Tommy Milner round at the top three at 145 points.

The six-hour Grand Prix at Michelin Raceway Road Atlanta will be held on Saturday, September 5th from 11:35 AM to 5:35 PM.

  1. Porsche actually has had the fastest car at most races this year and should have won most races. Unfortunately luck wasn’t on their side plus Corvette got a few breaks. This can’t go on forever and Porsche will catch up sooner than later.
