Hi All

Is the front caliper bigger on the S Q4 model? I just got a set of aftermarket wheels. It was tested by the seller with a local Ghibli to make sure it will clear.
Installed them yesterday, the front wheel scratched the caliper while the technician spin it. I wasn't very happy.
Now I had to get temporary universal spacers, order a set of custom spacers (5mm to fit both the hub and the wheel), and extended bolts to make it fit. Also with a scrapped caliper. The car is only 2 weeks old!! Not happy.
But the wheels do look awesome on the car.

So here is what i know.

The Standard Ghibli Front side disc is 345mm x 28 mm and for SQ4 its 360mm x 32mm and the front calipers are 4 piston on the standard and 6 piston on the SQ4 ...

So seemingly i think they might be a bit bigger...

@yxc145 - what company and wheel type was it? I am running into same problems trying to find 19" aftermatket wheels for my Ghibli RWD. Looks like the size of calipers limits significantly wheel design options.

It was bigger on SQ4 until the 2015 model. I was told all ghiblis since 2015 now have the same brakes as SQ4 ... This also solved the noise problem on (apparently) non SQ4

I have 20" wheels. It is not the diameter, but the off set that was the issue. I got the Niche Targa wheels.
