Oil and molyslip will make no difference in the 370z mate. Like the guys said it's a trait of the car and you do get use to it
I remember Toby (who was on here for a while) from a local Nissan dealership often said the same
mate loads of good 350z's out there but it pays to have it inspected by a specialist garage or decent engineer prior to a purchase, it could save you a fortune in the long run
I have a snooper one fitted to my car that is similar to this but without the advanced features they are good pieces of kit. I think this will go quick at that price
