Warning - you will love the Michelins so much that a week after install you will order the ESS unit. Regardless of which order you buy these or if you only buy one, you cannot go wrong as both are awesome products.
So I googled ESS flash and I see that it removes the limiter and improves performance. I have 2 questions:

Will this void my warranty in the US? I am leasing.
Is it worth the $800 USD?
