I think it's time has come!! to change my front rotors & pad...

I was wondering if it's possible to fit 390mm rotors on stock 19 wheels on CLS63 without performance package.

Local mechanic mentioned me about it could be possible if he adjust the

bracket further back..

Has anyone tried to install 390mm disc on stock rims??

Thanks..

That is what stock rotors are
At least my CLS63 came with it. I did not think there is another CLS63 model with smaller rotors??

Thanks for the reply but CLS63 with Performance package comes with 390mm.. otherwise it's 360mm as far as i know..

I attached picture of rims with performance package.. 390mm should look like this..

Yes, that on pic is what I have on my, I think that was only option in US but I may be wrong.

They won't fit. The calipers are longer to fit the larger diameter without hitting the inside of the wheel. Same parts as an S65 I think. If you've got the $ it is noticably better, but I'm not sure if the back brakes are larger too. If they are, you might have a pressure balance issue if you don't change all of them at once.
