Try to think about what you're saying. If you have several GT cars competing to the same rules the driver that wins rallies will be the best at going around corners, they will all be the same on the straights. If they're more difficult to drive than R5 then they will need a better driver to get the most from the car too.

As others have said an R5 car has a lot of advantages over a GT for rallying (suspension travel, 4wd etc), so if you want them to compete with each other you have to let the GT keep some advantage in other areas like power. Maybe the Spanish Porsches had too much advantage previously, its a challenge for rule-makers to get the balance right.
