Title: 362mm drilled discs
Post by: dan930 on August 08, 2014, 02:33:35 pm

I'm getting a slight on & off humming noise at around 60-70mph..(only 60-70mph) & sometimes between 40-50mph
My mate told me it might be the drilled discs as air gets through the holes...Aks checked everything out
But all is ok...

Sure its not the tyres?

If its brakes it will change under braking.
Could be many things but tyres would be a good shout!

The humming noise started after I fitted the BBK...

Does it happen on throttle as weight is transferred to the rear wheels?

We also did a wheel alignment at the same time.

Car is perfect so all I can think is pads running close to discs, or tyre noise as supersports are noisy.
