The Opel Astra TCR and the Peugeot 308 TCR have been given an increase in their minimum racing weights, whilst the LADA Vesta TCR has had its minimum weight reduced.
A new Technical Bulletin released by the TCR technical department states that both the Peugeot and the Opel must carry an additional 20 kg and 10 kg respectively.
The Opel is currently leading the drivers’ championship standings in TCR Germany, with Austrian racer Harald Proczyk at the top of the table after two wins.
The LADA, which runs only in the TCR Russia series at present, has been given a 20 kg weight reduction.
The changes take the base weight of the Peugeot to 1,305 kg, the Opel to 1,325 kg and the LADA to 1,335 kg.
An appendix to the bulletin lists the changes of the Maximum Boost Pressure and Engine Rotation imposed parameters for Audi, CUPRA / SEAT, Honda, Peugeot and Volkswagen models.
Further, following some controversy in the FIA WTCR event in Slovakia, a further Technical Bulletin has been issued to clarify the conditions and tolerances of the method for monitoring the turbocharger boost pressure.
The BoP applies immediately to this weekend’s races in The Netherlands (TCR Europe), Germany and Scandinavia.
