i have pss9's on my wagon and ausfart has them as well...the ride is unbelievable and no spacers and no problems with stock offset etc. the ride is as smooth as stock sport if the dampening setting is on a softer setting...
i almost purchased these fk's because i had a price similar to this one....and i almost wish i went with fk because of goooood price..although when i contacted fk north america they told me i would need spacers or rubbing would occur( spring to tire )but could not tell me what size etc. so i got nervous and ran...but now that i look back spacers probably are not a big deal
just make sure you know your wheel offset etc. and they could hook you up with the right spacers if even needed!!!
