Ok just a quick update, I still have the noise but I managed to get to bottom of the cause of the vibration.
As stated in my more recent thread, it turns out when the
garage that I always use for perfect balancing (hunter machine), didn't balance both my front tyres when fitting my new wheels.
I thought it was odd that there was no weights on these wheels..lol
Anyway its fixed now, fingers crossed, I have taken the car for a blast along the motorway so far so good.
Now I am going to try and get to the bottom of the moaning / whining noise from the NSF.
Going to regrease the cv joints and change the gearbox oil, going to use the stuff that the guys recommended earlier in this thread... MT90, just to see if that reduces the noise.
