I'm looking to install some SS brake lines on my M3. The car is mostly a DD but I do track and autocross the car 5-10 times a year. My last track day the brakes went super mushy and needed to push the brake to the floor to get some brake pressure. If I do a SS kit with just the front and rear lines without the mid will it still firm up the pedal for the track and not cause any issues.

The car has stock rotors, calipers with Hawk HPS pads. I do want to change out the pads as well for EBC yellowstuff. I know some will suggest a true track pad but I'm not serious enough or go enough to be swapping pads in and out.
