Aye, that'll be me. I used to be one of the most proliffic members over there. Still got some good friends over the too - Speedy36, Druck (groan), Hypo and a few others.
tbh, if you didnt think the RX8 handled that great, you will struggle with a Zed in standard form. (Did you have the standard RE040's on the rear of the Rex? If so, they were a major flaw of the car, and once changed dramatically changed the handling of the car. coincidentaly the Zed also has RE040's on as standard)
The Rex is still one of the best handling cars I've driven, and despite being nearly 100bhp less than my old Zed, I could still push it faster around my favourite twisties as it was so well balanced.
