I dunno Rob...
But everytime someone has contacted a manufacturer... even if ALL the owners WORLDWIDE ordered a part, it was usually not enough for a supplier to tool up.
You're welcome to take the lead on this one, but I for one am satified with cut springs and KYBs.
I think if ya really wanna go for an all out race suspension, modifying coil-overs is the way to go... especially for their adjustability. If interested, start a new thread and ask for photos and info.
