Re: K-Sport Coilovers are INSTALLED!
Sooooooo.....ride quality is mostly determined by spring rate and shock valving (stiffness). But there is also another factor and that is the location of the spring/shock in relation to the swing arc of the wheel/tire. OOOOO-techno talk i know...but think of it this way: The wheel being the outermost part of the suspension, applys the most amount of force to the spring/shock. The control arm/axle acts like a lever (2 inches of tire movement equates to a lesser amount of movement the farther inboard you go on the suspension) Therefore if you change where the spring is located relative to the wheel/tire, you change how much spring rate is needed to control body movement. On our jeeps the spring/strut is located as close to the wheel as it can be without completely re-engineering the spindle. On the rear, you have a small amount the spring could be moved outboard but you also have to account for the front/rear location of the spring due to how the axle is located to the body by the control arms. Using my mustang as an example-the stock front suspension uses a mcpherson strut(spindle bolted to the strut) with an inside mounted spring (located inboard of the strut). My original spring rate was 650 lb/in with my old lowering springs. When i converted to coil-overs, i now use 300 lb/in and get better handling. Why? Because the spring is now a full 6 inches closer to the wheel. The "jacking force" is reduced on the spring and now i have a better handling AND better riding car.
WTF DOES THIS ALL MEAN?!?!?
In relation to OUR Jeeps:
Without relocating the springs you won't get a change in the ride/handling without increasing the spring rate. That will give you a harsher ride. The only advantage the K-sport kit gives you is the ability to easily adjust ride height. I'm not dissing the kit at all, just stating that your ride quality won't change unless they use different spring rate/shock valving.
