It’s a short turnaround week for Corvette Racing and the Corvette C7.Rs as they head north of the border for the Mobil 1 Sports Car Grand Prix at Canadian Tire Motorsports Park after finishing P2 at Watkins Glen last Sunday.

And just because it’s the 4th of July weekend, don’t think for a moment that members of IMSA’s competition committee took the week off. Race organizers have issued a new Balance of Performance memo that directly, and exclusively, targets the Corvette C7.Rs.

The CTMP BoP Bulletin shows the Corvettes will have an additional 10kg (22 lbs) of weight added, bringing them up to 1250kg in total dry weight.

No other teams in GTLM had changes made to their BoP tables.

IMSA also made two changes in GTD, adding 20kg to the Acuras and four additional liters of fuel for the Lexus.

The Mobil 1 Sports Car Grand Prix presented by Acura begins at 1:05 p.m. ET on Sunday, July 7. It will air live on NBC beginning at 1 p.m. ET. Live audio coverage of practices, qualifying and the race from IMSA Radio is available on

  1. Looks like IMSA is busy with the….. “Bureau of Politics” BS again. Let’s have some REAL race competition,
    and stop playing games with the teams to cater to the fans of a certain make.

  2. I think that the makers of all these other much more expensive sports cars, just can’t stand the fact that they can’t compete with the C7.Rs including ford if left alone. Therefore they push a little cash towards IMSA to add weight to the corvettes or some other method to slow them down. SHAMEFUL!

  3. Wasn’t this done to the Corvettes before It sounds very familiar, penalize them for having faster cars (in class) by making them carry additional weight. It’s not fair, !

  4. IMSA should set a weight and horsepower limit, and as long as you fall within these limits no penalties should be applied. Then if you can’t win while within these limits get out of racing. This should apply weather the name on your car says Ford, Chevrolet or any other make. This also includes all those other much more expensive sports cars!
