One major issue faced when lowering a Fox mustang is the change that it makes to the front roll center of the car. The roll couple, defined by the front and rear roll center heights gets thrown out of whack because the front roll center height decreases at a much faster rate when lowered then the rear does. Using a dropped spindle helps to mitigate this factor by using spindle pin position to lower the car as opposed to reducing the height on the coil over. Two other benefit of this method of lowering the car are improved camber curve and more bump travel. It also appears that with these new spindles, we will be able step down the front spring rate a bit. Next time out at the track we will be running a set of 500 lbs/in Eibach Springs on the front of the car, as opposed to the 600 lbs/in springs we ran last time.
