Modify This: BMW M Performance and Lightweight for the BMW M4

I think the BMW M4 is already a very good car from the factory, especially with the Competition Package.  My whole goal for the car is to tastefully modify it, while keeping it as stock as possible, I wanted to add a few mods to make it mine and distinguish it from other M4's.

Looking good at magic hour.

Stringer going under the knife.

I added the BMW M Performance side blades and Lightweight front lip.  It goes well with the M Performance carbon fiber rear spoiler and mirror caps that's already on the car.

Now the question is should I call it day here or add the M Performance rear diffuser?  Hmmm...
