Here's a neat detail some might miss: See how the Strange Engineering master cylinder is braced? What's with that? When you pump the brakes to stage the car or to perform a burnout (and then set the roll control), the last thing you need is a firewall that flexes. Ditto with bringing the car down to a grinding halt after a pass. You might be surprised at how much a firewall can flex without this support (in a manual brake application).
