I fitted Toyo's to my 350Z and got about 25K out of the rears if I remember correctly. I have always been quite easy on tyres and brakes though. Sounds quite low to me!
That's a very nice looking zed you have there Phil. I had an Azure till I traded up to a 370. Your reg sounds familiar to me but I am not from the North East so not sure why?
I always wanted a 240Z when I was younger and thought I would never be able to own one so very happy to have a 370Z.
I would like to get a 240Z to restore but I think finding the right one is not easy.
Glad to hear you are loving the ownership of your 350Z. Got any pics?
