about Nissan fixing the window streak for free...I assume that you are talking about the grease left on the windows from the motors...

I have an 03 Touring, silverstone, 40k miles, automatic tranny...

I think that I might have the signs of tire feathering...I still have the original Bridgestone tires...They were pulled of the car with about 13k miles on them, and then put back on before selling the car to me...I think they have a total of about 15k miles on them...but I have started to hear some "roaring" noise when braking to slower speeds...

Have you had any experience with this problem?

Any advice on the proper ownership of a Z would be greatly appreciated...
