pretty clear to all that although engine problems are a primary reason for the drop off in the RBR performance in 2015 there is more to it than that ; if you compare the relative performance of Toro Rosso with the same engine the gap has closed considerably
so it seems that the titanium plates are achieving their primary objective of stopping the cars being run too low against the FIA rules , wear rate comparison looks very interesting
no wonder sparks are flying at RBR !
