For a small twin like the A320, a wet/contaminated 6365' [elevation 2635'] pavement can be challenging
only if improper landing techniques are factored, . . .such as touching down more than 1500' from the threshold of the runway, or flying faster than Vref+10kts. Reversers are always excluded from certificated stopping distances.
Many years ago I was often a passenger aboard Transbrasil B727s operating into CGH in wet weather without problems; the 72s being somewhat of a heavier airframe than the A320.
It's a pilot problem, not an airport problem. [I am a current pilot].
