In theory Cooling & Reliability will cause less damage to the engine & car, making you a little more constant for longer.
But the Race-viewer doesn't seem to notice the changes!. I've noticed the same damage percentages in the viewer, but after the race the damage is a little lower.
How can that be possible to have identical damage percentages, but have slightly less damage on the engine & cost 1 part less to repair the car?
SUGGESTION
Would it be possible to get the bars on Repair page shortened and percentage numbers wrote beside it?
It would be helpful, so that I can leave the race-viewer open and compare the two, to make sure they are in sync.
