Unless you’re competing in a class that has a minimum weight higher than the weight of your car without additional ballast, and mandates that the ballast can be mounted only in the passenger seat area, and prevents the battery from being mounted in the trunk, and allows the use of a Watts Link, then based off the above, the PHB is the better option.
For Project Budget 400whp Track Car, there is no question the best option is to stick with a stock PHB. It’s by far the cheapest option and extremely effective. By sticking with the PHB, we are saving $550-1,140 off the bottom line for a car that will end up performing just as good, if not better since we don’t have any minimum weight restrictions for our track-day fun.
Our 2014 Mustang GT’s worn-out stock suspension would not lead you to believe the platform’s true potential and capabilities. Unfortunately, this is what most people get an impression of when they’ve driven a rental car Mustang back in the day, or a friend’s relatively stock car on track.
We again turned to our friends at RareFab for the suspension install.
The new Steeda S197 Mustang Front Lower Control Arms with X11 Extended Ball Joints and Steeda Chromoly Lower Control Arms are ready to be installed.
When lowering the S197, the front Roll Center (RC) lowers more than the car’s Center of Gravity (CoG). This increases the distance between the RC and CoG, making the “Roll Moment” longer.
A longer roll moment decreases the car’s resistance to roll, thus increasing body roll, which is not good for the front-heavy Mustang with a strut suspension. Increased body roll requires more static camber to keep the desired contact patch when cornering.
A common solution for this is to stiffen the swaybar, but stiffer swaybars hurt braking performance and ride quality. In order to not rely on an extremely stiff swaybar, we decided to reduce body roll by changing the car’s suspension geometry and raise the front roll center with the Extended Ball Joints. Lowering the pivot point of the outer lower control arm (purple arrows), the instant center and roll centers are raised. This shortens the roll moment and increases the car’s resistance to roll, like stiffening a swaybar.
