Other places indicate this is a correct part number. I would imagine your springs are fine being you are in AZ. The only thing to consider is that there are no aftermarket replacement fronts available. Infiniti had a rebuild kit available, I think, for ~$400 per side for the fronts but I am not sure they are still sold. If you really like the car, and want to keep it on the road, you may want to look into a set of coilovers. BC Racing, Megan and K-Sport (maybe Godspeed for really low budget) make some. The prices range on options.
