Goodyear eagle f1 asymmetric 2 by far the best. i had dunlop sp sport max before and had to get rid of them because with them on, my scirocco might as well not have a first and second gear in the wet!
I bought a newer Bluetooth module of eBay for about 80 and then sold my original for 50. Just a simple swap and I now have full iphone 5 integration with my 2010 gt and rns510 head unit.
