The new CUPRA Leon Competición has been given a new, 10 mm lower ride height in a change to the TCR Balance of Performance [BoP] calculations with immediate effect.
The car, which made its racing début in TCR Italy earlier this year, has been racing in the Italian, Scandinavian and Eastern European TCR sprint competitions thus far.
Salvatore Tavano gave the car its first victory in TCR Italy in July, whilst Robert Dahlgren was also victorious in TCR Scandinavia at Karlskoga earlier this month.
The BoP adjustment sees the ride height lowered from 80 mm to 70 mm. Elsewhere, the Opel Astra TCR has been given a reduction in ballast from 20 kg to 10 kg.
Also changed are some details relating to the ECU software parameters for the Honda Civic Type-R FK8 TCR and the Peugeot 308 TCR.
The new BoP bulletin also includes a separate list applicable to endurance races, which has a lower target racing weight of 1,250 kg compared to the 1,265 kg applicable to TCR sprint races.
The majority of cars have a target racing weight of 1,250 kg for endurance races, with the exception of the VAG DSG cars, which are 10 kg lower at 1,240 kg. The Peugeot 308 Racing Cup target weight for endurance races is lower still at 1,210 kg.
The assigned ballast for endurance races is reduced by 50 % compared to that in TCR sprint races.
