***Various Balance of Performance updates have come to CTSC ahead of the weekend. Most noteworthy are the ST class pace-setting Porsche Cayman and also the Porsche Boxster have each been given a 50-pound weight increase to 2870 pounds, and a 100 maximum rpm reduction down to 7350; additionally, the GS class Chevrolet Camaro will also increase 50 pounds to 3550 and see a maximum wicker height reduction by 12mm, down to 13 mm.

***Other BoP adjustments within CTSC: the GS class Aston Martin GT4 will have a fifth gear increase to maximum 7500 rpms; the ST class BMW 128i and 328i each have a greater fuel cell, up 0.5 gallons to 18.5; the ST class Hyundai Genesis coupe and Nissan Altima coupe both get weight breaks (25 and 50 pounds off, respectively); lastly the ST class Mazda MX-5 adds 40 pounds.

***The ST points-leading Murillo Racing entry of Eric Foss and Jeff Mosing in the No. 56 car switches from a BMW 328i to a Porsche Cayman this race, the ex-Bodymotion Racing chassis. Murillo’s sister car, the No. 65, premiered a Boxster at Indianapolis in the hands of Tim Probert and Brent Mosing, after a fire damaged the No. 65 BMW 328i at Canadian Tire Motorsport Park. Foss holds a six-point lead on Wayne Nonnamaker, in the No. 42 Team Sahlen Cayman, entering the weekend.

***Doran Racing has had quite a week-plus in preparation for the CTSC weekend. The team’s No. 14 Nissan 370Z, driven by BJ Zacharias and Brad Jaeger, needed to be repaired following an accident last week at Mid-Ohio in a one-off World Challenge appearance; Zacharias made contact with another car. The team’s No. 41 chassis, which was damaged at Watkins Glen, has been rebuilt and is back in action this weekend as the No. 14, while the No. 41 car of John Farano and David Empringham continues on from Indianapolis two weeks ago.

***Turner Motorsport spent most of Friday rebuilding its No. 97 BMW M3 following an accident by Tom Kimber-Smith at Turn 7 during Thursday’s test day. The car missed both Friday practice sessions, but the crew’s efforts made it possible for “TKS” to make qualifying.

***Mantella Autosport, which led the opening practice session with Mark Wilkins and Anthony Mantella in the team’s No. 8 Aston Martin Vantage, also had a thrash to make it to Road America. The team got its engine back late Saturday night and had a shakedown test on Monday before coming to Road America this weekend.

***Racers Edge Motorsports will withdraw its No. 79 Ford Mustang Boss 302R, following an accident for Chris Beaufait exiting Turn 14 in Friday morning’s first practice. Beaufait was scheduled to drive with Nick Galante. The team’s second car, David Levine and Lucas Bize in the No. 78, continues as planned; Bize is pulling double duty this weekend between CTSC and Mazda MX-5 Cup.
