The idea of these two modifications is to increase the flex in the chassis, so that the car can roll or lean into the corner more, which increases grip on medium to low traction surfaces (asphalt). I think you call it torsional flex, i.e. if you take your car and hold the front and back and twist your hands in opposite directions.
So to make the car flex more, you can use less screws to secure the top plate, or put rubber orings below the 4 screws that attach the top deck near the spur.
A lot of guys detach the motor mount from the rear bulkhead by removing the screw there, this increases flex, and more importantly makes the flex more symmetric. If you are being thorough you have to grind the bulkhead or motor plate so there is a gap, but I'm happy without the gap.
