thanks for your input
I'm leaning more towards the NT05's, don't care so much for wet weather performance, I mean it's good to have obviously but I only commute to work when it's raining and stuck in traffic half the time.
have you driven in these with a Z though? I use my car a bit for work and the stock tyres are quite noisy, this doesn't bother me myself but sometimes when I'm on a call people can barely hear me if i'm on the freeway.
