Look up reviews on those coils any you'll get your answer. Just google "Solowerks coilover review gti mk6" and you'll find plenty of threads not just from the GolfMK6 forums.
As for what I've read, most people say you get what you pay for in the end. Your ride quality won't be horrific but it won't be very good either. Specially if you're going to drop it on coils. It all depends on the person. Some people can tolerate, others can't. Roads also matter a great deal. I thought Seattle downtown roads were bad, but compared to the east cost, they're nothing. They're actually decent. My cousin runs dropped Raceland coils on his Scion TC and he says the ride isn't actually half bad. But, as you can tell, the majority of this forum bags on Raceland coils.
