well the A539 is the old one (before paradas0, i got them on my swift gti, they were good but nothing like the parada's, (i run them at 195/50/15). lonve the tread pattern on the parada too

these S drive have a good write up, they seem to be mostly for cars with big or wide rims like porsches and stuff so im gonna give them a go.
hope they are as good as the parada, my golf handles like a go kart with them and the coilovers
