Replacing Brakes.

[Kaikora]

Hi all! Time to ask another question to gather some information and make a nice informed decision. 
 

I need to replace my rear brake pads and so will do the disks at the same time. My front are okay for the mean time. 
I do not take my 350 on track and don’t necessarily go exceedingly fast where I need super power to stop but I would like to upgrade a little for safety and comfort. 
 

which set do people recommend? I am thinking of getting EBC slotted with red stuff pads. 
 

TIA!
