IMSA’s Competition Committee released the season’s first technical bulletin outlining the Balance of Performance for the three classes ahead of the official Roar Before the 24 testing session scheduled for January 3-5th. The test is mandatory for all teams competing at the 2020 Rolex 24 at Daytona later in the month.
Scheduled for Daytona are seven entries in GTLM representing four manufacturers: BMW, Chevrolet, Ferrari, and Porsche. The Corvette C8.R and Porsche’s 911 RSR are new homologations for 2020 and both had their initial BoP set while Ferrari saw an increase in performance over last year’s settings. BMW’s BoP was unchanged from 2019’s Rolex 24.
The initial Balance of Performance table for the Corvette C8.R includes:
- Minimum weight: 1260 kg
- Air Restrictor: 44.0mm
- Redline: 7400 rpm
- Minimum Rear Wing Angle: 2.25 deg
- Gurney Minimum Height: 15.0mm
- Fuel Type: E20
- Minimum Lambda Number: 0.88
- Maximum Fuel Capacity: 89 liters
- Minimum Full Refueling Time: 34.0 seconds
Following the Roar Before the 24 test weekend, the IMSA Competition Committee will review the data and determine any final updates to BoP prior to the start of the 2020 Rolex 24 at Daytona.
One of the interesting developments for this year’s Rolex 24 is that IMSA is working to slow the GTD class as a whole to create more separation between them and the GTLM class. In some areas of the track, the GTD cars were just as fast but now the GTLM racers should be able to get around them a little quicker.
As the Roar Before the 24 test requires all teams and drivers to be present, it also means that it will most likely be the first showing of Corvette Racing’s No. 3 C8.R with the Yellow and Silver livery. So far only the Silver and Yellow No. 4 C8.R has been shown so we’re looking forward to seeing it in action for the first time.

Looks like more of this BoP nonsense. Cars that are running slower, and can’t win, need to step up their game, NOT penalizing the fastest cars. That’s why the old Cam-AM serious was so popular, you improved the performance of the race car, NOT playing politics to please the owners and/or fans of the makes running in the series.
I agree with Butler 100% This whole BoP business is idiotic. Just go racing. Let it be a test of who is the best combination of technology, car craft & preparation and driver skill. Colin Chapman must be turning over in his grave when this BoP charade starts up.
I also agree with Mr. Butler.
It is idiotic that we stifle inventiveness. Nearly all forms of auto racing are being destroyed by this cookie-cutter mentality. Does anyone remember the IROC series with the identical Camaros? It was a complete failure. Attendance and interest is waning in F1, Endurance Racing and NASCAR due the totally unnecessary controls being placed on them.
As goes the expression, The definition of insanity is and repeating the same whilst expecting a different result.

Before one can complain about the BOP numbers quoted for the C 8 R above we need to know
what last years BOP numbers were for the C 7 R. Yes I agree BOP sucks and the slower cars
need to catch up but BOP makes for closer and more exciting racing in the eyes of IMSA I believe.
If the C 8 R has been given an unfair BOP to start, then we should complain since it has not been on the track in race conditions. I know that about 2 weeks ago the C 8 R was at Daytona
doing a private track session. We live near Daytona and know who is doing what.
Jim F., if you read this blog let racing be racing and get IMSA to back off.
It’s a hard call. It is called “racing”. Not “best display of speed technology”. While I would love to see what the Corvette team could do unharnessed, I also love to see close tight door to door racing. That is when the best drivers really shine. Whenever a car develops a 1mph advantage, that car pulls away from the field, and the race is essentially over barring human mistakes.
On a side note, I hope the team returns to the full yellow livery. It has a high intimidation factor in the rear view mirror, and the competition can’t say “sorry, I didn’t see you”. The year they switched to the dark blue livery was a disaster. Should be an interesting season!
Well if they are going to set BoP without the cars hitting the track then why bother having The Roar.
Have to admit I don’t understand all these numbers and Lambda, and Gurney stuff. But I agree that restrictions just don’t make sense. The cars ae supposed to be pushed to the limit, why lower the limit? I understand the need for safety, so why not make them all race go karts? They’re safer.
@George. The real problem with the BoP is the last “tweak” before the race based on practice lap times. This gives teams the incentive to “sandbag” their lap times in the hope of a positive adjustment to their BoP.
According to the homagulation rules, how long does Chevy have until it must provide the public a motor similar to the C8-R?
If you can’t compete stay home
racing is passing not following the leader.
The chairman of the IMSA Competition Committee must be either Bernie Sanders or Elizabeth Warren. They are determined to redistribute the points and wins to less fortunate teams. So much for building a better mouse trap. At the same time, I must disagree with Montana Bob, “interest and interest in Formula 1” is not waning, The latest attendance figures for last F 1 season showed significantly higher attendance figures from the previous season. Thus an increase from a 20 race season to 22 races next season.
