I've heard the RSR's are pretty noisy, and i occasionally have to do long highway trips, so i don't want tyre noise to be too bad. I'm going to Adelaide over Easter, and 1600 km round trips on the coarse highway with noisy tyres gets annoying.

I also use the RSRs on my AW11 and they handle putting the power down well in the dry. In the wet, well its wet so I take it easy and its not a problem. Too much gas will get them spinning easily.
 
I think they probably are a bit noisy but its hard to tell in an old rattly AW11 :) 
 
On my wife's Mercedes it has Continental Contisport contact tyres fitted and they are very quiet and very grippy wet and dry.
