## Background
FIELD OF INVENTION
Embodiments of the present invention relate to automotive suspension systems.
BACKGROUND
From the onset of the automobile age, hobbyists and mechanics have sought to personalize their vehicles. Traditionally, automotive manufacturers warehoused parts for repairing currently supported product lines. As product lines became obsolete, aftermarket industries arose to meet the demands of on-the-road and collector's vehicles. In addition, highly modified vehicles became popular as speed and handling became more important to owners.
Conventional aftermarket modifications were, of necessity, highly specific to a particular product line. For example, some multiply dependent components such as suspension components were not readily available since the cost of development to assure compatibility remained high. In some examples, extension modification to stock parts was required to the extent that returning to an original configuration was difficult or impossible. As such, highly modified vehicles became “one-off” and “one-way” propositions. In addition, because the costs for such modifications were high and could not be amortized over a period of time, these types of modifications remained out of reach of the average hobbyist. As such, modular suspension systems are presented herein.

DETAILED DESCRIPTION
The present invention will now be described in detail with reference to a few embodiments thereof as illustrated in the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without some or all of these specific details. In other instances, well known process steps and/or structures have not been described in detail in order to not unnecessarily obscure the present invention.
FIG. 1 is an illustrative representation of a modular suspension system in accordance with embodiments of the present invention. As noted above, modifying a stock vehicle may require high costs and irreparable modifications. Nowhere are these issues more prevalent than in suspension modification. One reason contributing to the difficulty of modifying suspension is that the geometry of the interlinked parts must either be maintained or modified in such as way as to equal or improve stock configurations. For example, a stock control arm typically has a fixed geometry designed to operate within a specific range of use. For this reason adjustments to the geometry to accommodate a different range of use, such as racing, is limited or impossible. In addition, any changes to a stock control arm must account for all other geometry in the suspension system for the change to be effective and safe. Systems provided herein attempt to allow a user to modify their stock suspension in a way that is safe, effective, and cost sensitive. In order to accomplish this, systems must provide improvements over stock components and be forwardly and backwardly interchangeable with stock components.
For example, as illustrated, stock suspension 102 may be modified with any of the following components: control arm component 104, spindle component 106, shock component 108, disc brake component 110, forward strut component 112, and sway bar component 114. Where systems presented differ significantly from conventional solutions is that any of the components may be changed in any order from stock to custom and from custom to stock. For example, a user may choose control arm component 104 to modify stock suspension 102. In utilizing control arm component 104, the user may simply replace the stock components with the new components without any other modification to any other stock component. If the improvements are acceptable, the user may then select any other component (or none) for the future. If the improvements are not acceptable, the user may then simply replace the modified component with the stock component to return the stock suspension to its original configuration. In this manner, the user may selectively change components as needed or as may be afforded. Furthermore, each modification may add additional customization such as adjustability, improved geometry, and increased performance. Still further, combinations of modifications may be utilized at will since the parts are interchangeable with stock parts and require no other modifications to stock components. Thus, for example, a user may utilize spindle component 106 alone or in combination with any of the other components.
FIG. 2 is an illustrative representation of a pair of asymmetrical control arm components 200 in accordance with embodiments of the present invention. As contemplated herein, a pair of asymmetrical control arm components may include a control arm connection geometry sized to replace a pair of stock control arm components. Importantly and as noted above, the pair of asymmetrical control arm components may be compatible with all other stock components of the stock automobile without modification of the stock components. In addition, the pair of asymmetrical control arm components may include additional control arm customization. For example, embodiments may provide an increased range of adjustability over the pair of stock control arm components resulting in an increased range of caster and camber alterations over the pair of stock control arm components. This adjustability may provide improved handling characteristics such as increased high speed stability through additional positive caster which may be unattainable when using the stock upper control arms. In embodiments, adjustment point 202 and 204 may be utilized to accomplish this customization.
FIG. 3 is an illustrative representation of a pair of spindle components 300 in accordance with embodiments of the present invention. As contemplated herein, a pair of spindle components may include a spindle connection geometry sized to replace a pair of stock spindle components. Importantly and as noted above, the pair of spindle components may be compatible with all other stock components of the stock automobile without modification of the stock components. In addition, the pair of spindle components include additional spindle customization. For example, embodiments may provide a lowering of the stock automobile's center of gravity thereby improving aerodynamic characteristics, fuel economy, and handling over the pair of stock spindle components; and a rotation of a brake caliper mount thereby allowing larger calipers over the pair of stock spindle components. In some embodiments, spindle components may further include a pair of lower spindle ball joint adapters that allow a relocation of a lower control arm ball joint pivot point. The utilization of lower spindle ball joint adapters allow the relocation of the lower control arm ball joint pivot point, providing the opportunity to alter the inner lower control arm pivot to finally arrive at a point where full advantage is taken of the progressive implementation of the aforementioned components resulting in reduced side scrub, camber change throughout suspension travel, increased positive caster fur high speed stability, and reduced bump steer. The vehicle is ultimately more stable under all conditions, handles better, and has a more pleasant ride quality. In some embodiments, lower spindle ball joint adapter 310 may be utilized to move the captive stock ball joint away from being bolted to the spindle and allows the ball joint to be captive in the control arm instead. Relocation provides a pivot point lower by about 2′′ which only then allows the alteration of the lower arm pivot points.
FIG. 4 is an illustrative representation of a coil-over shock component 400 in accordance with embodiments of the present invention. As contemplated herein, a pair of coil-over shock components may include a shock connection geometry sized to replace a pair of stock shock components. Importantly and as noted above, the pair of coil-over shock components may be compatible with all other stock components of the stock automobile without modification of the stock components. In addition, the pair of coil-over shock components may include additional shock customization. For example, embodiments may provide removal of a stock torsion bar suspension thereby increasing an engine compartment space over the pair of stock shock components; and an external adjustment of damping characteristic of the pair of coil-over shock components. In some embodiments, increasing engine compartment space may allow for use of larger headers. In addition, as illustrated, adapter 402 may be provided for matching placement of the pair of coil-over shock components with the pair of stock shock components. As may be appreciated, adapters allow for both stock mounting and custom mounting of some components. Thus, in embodiments, a user may initially use a stock mounting configuration, but with further modification, later use a modified mounting configuration.
FIG. 5 is an illustrative representation of a pair of disc brake components 500 in accordance with embodiments of the present invention. In embodiments, disc brake component 500 may include rotor 502 and caliper 504. As contemplated herein, a pair of disc brake components may include a disc brake geometry sized to replace a pair of stock brake components. Importantly and as noted above, the pair of disc brake components may be compatible with all other stock components of the stock automobile without modification of the stock components. In addition, the pair of disc brake components may include additional disc brake customization. For example, embodiments may provide an increased brake rotor diameter over the pair of stock brake components; and an increased cooling effect achieved by one of, drilling, slotting, and venting a brake rotor of the pair of disc brake components. It may be appreciated that larger caliper pistons or increased number of pistons puts more torque on the rotor over a larger surface area, stopping the vehicle more quickly. Use of modem materials in the calipers allows more rapid cooling and improvements in caliper design reduces caliper distortion, also increasing efficiency.
FIG. 6 is an illustrative representation of a pair of forward strut components 600 in accordance with embodiments of the present invention. As contemplated herein, a pair of forward strut components may include a forward strut geometry sized to be compatible with all other stock components. Importantly and as noted above, the pair of a forward strut components may be compatible with all other stock components of the stock automobile without modification of the stock components. In addition, the pair of forward strut components may include additional forward strut customization. For example, embodiments may provide a resistance to torsional twist and distortion created by an engine torque over stock components. It may be appreciated that large resistance to torsional twist and distortion created by the engine's torque being applied to the front frame rails, may result in more torque being applied to the ground rather than spent in distorting the chassis. The lift of the engine on the driver's side and the downward push on the passenger's side becomes accordingly more controllable with forward strut component embodiments. One beneficial byproduct of the additional rigidity is a reduction in bending and fracturing of the inner sheet metal fender structures.
FIG. 7 is an illustrative representation of sway bar component 700 in accordance with embodiments of the present invention. As contemplated herein, a sway bar component may include a sway bar geometry sized to be compatible with all other stock components. Importantly and as noted above, the sway bar component may be compatible with all other stock components of the stock automobile without modification of the stock components. In addition, the sway bar component may include additional sway bar customization. For example, embodiments may provide a reduction in body roll thereby maintaining an ideal (or established) suspension geometry during corning resulting in better traction and associated predictability in handling.
Other Customization
In some embodiments, a rack and pinion steering assembly may replace a stock steering box. This replacement makes for a much more modern and compact method of steering on the car. In addition, a rack and pinion steering assembly embodiment is lighter and may be mounted forward of the front axle centerline to increase oil pan and header clearance. As may be appreciated a larger oil pan provides an increased oil capacity without mandating that the pan hang below the main k-frame to do so. Rack and pinion steering assembly embodiments may be a manual self-contained unit or paired with a power steering pump.
