Hey Mark, awesome car man, love the set up, so jealous. since u are in japan and are in contact with hks, would you be able to do me a favour, could you ask them do they have rebuild kits or anything for hks coilovers still, as i have a set in my R33 gtr, and was wondering how they go about them in japan when they leak? as im sure i will come across this sooner or later, and they are an awesome coilover. so far performance wholesale here in qld seem to be the sole hks distributor in oz, and i was told by them nobody in australia services them really, then was told to try a local place in brissy who might be able to rebuild them.
You can PM me info if u find anything out
Many Thanks
Darren
