You can't have your cake and eat it too. If you design something to take the abuse track driving will throw at it, there are going to be drawbacks somewhere. Parts running hotter will require looser clearances to accommodate thermal expansion, which contributes to less than ideal performance at lower temperatures. Not much the engineers can do about that.
