"Tires were not the problem. Front passenger side tire still vibrates when hot at low speeds (5-20mph). Now the front brake seems to have a loud metallic squeal that only occurs only when the car is hot. Brakes are only 6 months old. Brakes are always quiet on cool days (<75 degrees).
Obviously something is going in the front. Any ideas how to troubleshoot? I may need to take it to the mechanic when it is hot."

As for the squeal, I would think something like a wheel bearing going bad but if the squeal only happens when compress the brakes, it most likely the pads. Cheap metallic pads are to me a no no...they will feel good but once they start to wear you can get a squeal. Good pads on a Porsche are semi-metallic compound, yes , more dust.
