Got a reply from TEIN today regarding my inquiry on something for our model:
Thank you for your inquiry. At the current moment we are looking for a test vehicle. Once our R&D stage has been completed we can potentially release a lowering spring kit and coilover kit. Please check with us periodically to confirm if we have release product for your particular application.
Should you have any further questions, please feel free to contact us.

Anyone down that way? Maybe they're still looking!
