Got to see and go for a spin in the car. It's pretty snazzy!
Steven's done a lot of cool little touches that aren't really laid out in this thread. The instrument panel is a really minimalist laser cut aluminum panel mounting SpeedHut gauges with center tach.
The stock center stack is gone, with only the main dash center vent discharge opening remaining... Steven's developing a 3D printed faceplate that screws to the original center stack mounting points on that discharge and mounts only the HVAC control panel. A/C works and the fast steering looks like a blast, although I did not get to drive the car myself... I would never fit into Steven's seat

Steven's also designed a foot pad/dead pedal combo for better foot placement on the pedals with the OE carpet removed from the car. I think he's shown that elsewhere on the forum.
The passenger side still has carpet, but also has a racing seat that's a little tight for me, but I mostly fit. Four point harnesses in both seats with a handy custom harness bar that bolts to the OEM shoulder belt mounts in the B-pillar.
