I moved my Ineos cross bar and (under-fitted) Ineos light bar back behind the safari windows as it was way too noisy (wind) at the front of the car. However I had to flip the light bar to bring on top of the cross bar as there wasn’t enough clearance underneath the cross bar if placed by the B Pillar. I also added rubber strips to help noise reduction.
So it’s now behind the safari windows and works very well and with little noise.
I don’t notice any major light coming into the cabin, but you can see it beaming over the top of the safari windows if you look up, but it’s not distracting.
