Hey thanks man! I can't offer any specific advice re seats. All I know it that a harness holds your body very still and in an impact your head is too free to move, hence the head restraint recommendation. A stock seat belt allows your body to move a bit. I guess a serious race setup is a race seat, harness and Hans device or similar.

Good luck with your build.

Great looking build. I was also making best handling NA build but its definitively not that anymore. How do you like the CAE Short Shifter?

I have a little hard time to understand the concept. Looks more like a time attack, autoX build than something to have fun with on twisty roads without braking the speed limits to much.
