Stewards clarify Kostecki disqualification findings Repco Supercars Championship By James Pavey Motorsport Australia issued a statement this morning to clarify parts of the Stewards’ decision handed down to Jake Kostecki following Sunday’s race in Townsville. Matt Stone Racing (MSR) was initially charged for a breach of rule D17.1.17 in that the minimum tyre pressure on car #34 for both the left and right rear tyres was below the required 17psi on the grid prior to the race start. Subsequent evidence has been presented following the Stewards’ Hearing to indicate only the one tyre was below the minimum pressures, not two as initially stated.
