I haven't bought them for the 370z yet but I did it with my 350z twice before getting rid of the car. i heard it from a friend with an evo so I went in and asked and they confirmed it. I think they're basically banking on you to lost the receipt or waiting too long to bring them in. they're good for driving aroudn teh city but I went on a canyon run once and they definitely weren't the best for that.
that's the 370z pad and if you click it it says limited lifetime warranty. Give your local store a call and ask them
