Our BMC stopper is designed to mitigate firewall flexing greatly at those moments when the realization hits you that you have brakes  - aka late braking.
 
Based on a 15 year old design thrown together the night before an autocross event (man it was ugly but did the job), it's since improved.  It's now a two piece with the additional third anchor point at the top of the strut tower.  The stopper is now designed to sit perpendicular to the master cylinder's orientation rather than the horizon for more even distribution and improved aesthetics.  It retains the adjustable elevator bolt from the original but now with 2" of wiggle room to work with.
 
This will work with the GTS power steering reservoir still in place with some slight adjusting of the one protruding reservoir mount (see image of unfinished unit installed in GTS chassis w/ the mentioned ps reservoir bracket).
