E90 LCI 325i Brakes

[nikolarun]

So,
I was on ebay over the weekend and after a few "sherries" i got myself a set of bigger calipers for the 335i.

Have I done something stupid ? I have had the car for 6 months and never been that happy with the brakes.

I paid less than the price showing. I have the 18" wheels so hoping they will fit. Do I need to get any brackets to be able to bolt them on ?

I would also need new discs on the front and back. I was thinking these should do the job, but are there any recommendations ?

Also can anyone point me to the correct pad size ? I was thinking of getting something like Mintex 1144s or similar pads I have used them before and been very happy.

Any other suggestions are welcomed.
