Just did the series (not complete) with Porsche (don't have other cars). Can confirm that PR 82 unlocks Porsche Performance Showdown and PR 84 is enough to get 33 trophies.

So your last suggested upgrade plan is needed - that's what I used. I hope I'm replying too late and you already bought upgrades because the sale just ended an hour ago 😊
