Mac is right, don’t lift a 420 without a stretch, that rear UJ will bust pretty quickly. In stock form there pretty close to there maximum angle anyway.
You have two options...
Void the warranty, get the tires, a 53% GR and a rear swing arm stretch.
Or... Stick with what you got until the warranty is up.
