What are my front brake upgrade options?

On the contrary, stick with ATE rotors, the Brembos seem to be
of lesser quality. If you've had problems w/ the ATEs, maybe Brembo
is worth a try but I'd go w/ Zimmermann or Balo first.
Don't get cross-drilled rotors.
Try stainless steel lines and good pads and fluid- my recommendations:
Ensure the calipers are working fine, first
Stainless steel lines all around
Porterfield R4S, Kerr Friction or Pagid Orange pads
ATE super blue, OEM Porsche, Motul 600 or Castrol SR-F fluid, flush
For a 5ktq, that should be sufficient unless you track the car- that's
a pretty extreme setup I've listed and it will probably squeal a bit.

Thanks for all the tips guys, I am going to try Brembo rotors with KVR
carbon metallic pads, and see how they work before I do a conversion.
