I haven't noticed any traction issues yet. I also haven't pushed it very hard from a standstill, have the dcc which adjusts shock rates during accel, the dsg, and a vaq lsd. Even the super cheap stock tires seem adequate at the moment. I'll upgrade to pss down the road.
For detailing once I took delivery I rewashed it, clay bar, Klasse twins( aio and sg). I touch up with meguiars ultimate quick wax which is a synthetic wax atter every wash.
