They go to their box-o-springs in the back room and get something that is close to what should be good for 80% of the users in the world. As you know everybody has their car set up slightly differently (sway bars, weight removal, ride height, stereo components, aero, etc.) there is no possible way to please everybody with an out of the box solution.
Jesse, I agree with you on the statement of “add more front grip, don’t just remove rear grip”. Personally my approach would be to try and set the car up for a blanced setup and then tweak components to shift the grip to the front, this is where spending the cash on adjustable components pays off.
