Need your help.
Recently I added onto my 370, fiber nismo body kits.
I replaced the diff mounting to poly diff mountings from whiteline
Transmission mount replaced to oem stock ones
25mm Spacers added to the all 4 sides
Problem:
When I drive around 110 km/h and above there is an annoying vibration in the car I can feel it and see it on the steering wheel especially.
I thought it was tires, so refilled the tires. The vibration reduced slightly but is still there.
Am I missing something?
Could use your help guys.
