HS aren't available anymore, the TT's are the replacement for these. I hardly sell any of these anymore, partly due to stock issues, but also because a set of HR's with lighter springs are a better unit and comparable in comfort.

1kg lighter springs than standard front and rear make a really good street setup for those wanting slightly more comfort, but in my opinion, the stock spring rates are a perfect balance between performance and not rattling your fillings out.. not too stiff and not too soft. You can't expect ANY coilover to have a ride or NVH like a set of springs and struts, even a set of lowered ones.
