Blitz ZZ-R Coilovers

[Surruk]

Does anyone have any experience (or knowledge at all for that matter) of the Blitz zz-r coilover range?

They seem fairly popular in Japan and apparently get decent feedback over there as a street and mild track set up, but its close to impossible to find any experience with them outside of japan. Anyone in our community have or have tried them? thoughts?

They are built with replaceable shock units that can be purchased for around $100 a corner. That's an idea that I like because it should minimise expensive Australian labour costs down the road.

Some say they are made in the same factory as BC, but I'm yet to see anything to back that up other than hear say. Besides, being made at the same place does not = identical products.
