It has to do with the rear axle not being ideal for a floating caliper. I wouldn't be surprised to see rear Brembos after the 2015.

 

What suspension are you looking at? I've been leaning towards the FRPP adjustable kit. I too have the track pack and hate the anemic looking rear brakes, but like others have said, the car nose dives too much to worry about them yet.

 

My car is new and I have not been able to drive it much. Hoping all the rain will stop here in Florida so I can.

Its been my experience that when the car dives to much that can be fixed with the right Shocks. I would like the Brakes to look the same like the other cars do. It's more aesthetics for me than anything. The braking so for seems good.

I have one of the last built cars and do not seem to have a lot of the same issues everyone complains about. If anything I would pick the FRPP adjustable as well.

 

I've been researching suspension options as well. FRPP assembled handling pack is one of the top choices for me right now. Also recently I've been looking at the assembled spring/struts Vorshlag is offering. You can even choose 2 different FRPP springs with it, which is cool.

I actually took it up to Stillen and they installed it.
