Type-HR, etc. The Type-RA is TEIN's top RACING suspension setup for the Z32. The only TEIN setups I have seen other people here have is the Type-HA which is TEIN's sport suspension setup; the Type-HA has regular steel non-rebuildable shocks while the Type-RA has the duraluminum rebuildable LARGER diameter shocks... also with the regular Type-HA, the pillow-ball upper mounts are extra cost options, but they come standard with the Type-RA...
