My B210 is an early 1976 Jap spec car with H150 etc. I picked up a late model Borg Warner diff for something a bit stronger and I have a few spare centres to weld up before building a proper shortened LSD diff. I picked up the 810 for the L20b and I will stitch on some engine mounts (from a wrecked Stanza, 610 cross members are not so common any more...). I plan to use the 810 struts as I'm considering club registering the car, and not having adapters etc for brakes simplifies engineering certification in Victoria, Australia. I'm also thinking 2" struts opens up a few extra options for inserts and coil over kits.
What springs are common use with the VW Golf/Rabbit Bilsteins in shortened struts?
