Yeah Steve, the website can be a bit misleading.
If you are running Brembo calipers then I have the correct Goodridge lines in stock, which can be included with your other stuff which will be shipping Monday.
Just drop me a PM.
Alex.
What year and model is your car?
Did you fit a genuine Nissan CPS?
What is the current stored fault code?
Might be the knock sensor or perhaps the flywheel.
Perhaps even a cam position sensor.
Let me have the fault code.
If you continue to bounce them off the kerbs then not very long.
Seriously, the mileage from a set of tyres will depend on many factors including your driving style and if your geometry is spot on and if the tyre pressures are correctly inflated.
The tyre size may not be helping but the main tyre issue is the mixed tyre brands which are just not compatible with the 370 and certainly not conducive to comfortable handling.
The Mishimoto comes with a new aluminum fan shroud and fits exactly as OEM.
