Well, after sending email to both comptech and neuspeed with no reply whatsoever about rear sway bars, I decided to search for somthing local.

To my amazement, Whiteline actually supplied rear sway bars for the Euro. Here's the email I got:

Hello Victor,

Thank you for your interest in Whiteline suspension components.

We do have a listing for a rear sway bar to suit your model vehicle, the part number is # BHR80, with a retail price of $228.00.
However we do not have a listing for a strut brace to suit your vehicle.

I hope this helps you.
Regards,
Wayne Cunningham
So there you have it. Hopefully I'll be getting one installed soon, along with Baboo's Eibach prokit
