If you're concerned with warranties but want to push a 380hp car to go meaningfully faster then you might be looking at an expensive dead end. It's already really fast. Going faster is just going to require voiding some warranties. Or lying about it later.
Spend your money on things that make you happy first is what I would suggest. Unless that 5% is super important or just a happy side-effect.
