I was able to access the transmission, e-Brake, and rear brake pads from underneath in my last Unique 427SC faster than removing and re-installing the seats and tunnel in my current ERA for the same purpose.

For me, both methods in each of these cars seemed to have their strong points and weak points. Its kind of a toss up to me. The smaller rear access panel idea for the brakes sounds like a good idea though.

You might want to check with Alan or Maurice at Unique on the structural floorpan implications (if any) with making a removable tunnel before you do it on the Unique. I'd bet they have looked into it a least once already. I imagine you would want to consider creating some sort of support strips to screw in to along the cutout edges on the Unique if decided to make it a removable tunnel.
