And you know the reason why done this way...with typical approach, exhaust below the car it's too low and having issues when placing the car at the trailer etc...

Hi... Exactly - far too low

Thanks..

how much heat does it generate inside the car?... and did cutting the floor board create any weakness in the structure?

I like the new giubo flange, Maybe I can make an Alfa flywheel to BMW guibo adapter.

Pretty sure cutting the flat sections floor will weaken the structure a little, but with a full cage which now becomes the new backbone of the car, it's probably not an issue.

I think Giulietta EVO2 said the ring and pinion apparently is shite.
I use more HP and torque than your 3 litre 24V with a 4.56 differential on the track and there are no issues other than a big grin... :D
