So far I've written to these companies and these are their responses:
KW - Owns Belltech & ST Suspension so no.
BCRacing - Declined
Hotchkis - Declined
KSport - Declined
Cusco - Declined (unless shipped truck to Japan)
ICON - Requested extended and collapsed lengths
I can't find an email for H&R or Bilstein
If you know of other brands, please post!
