• Highest strength to weight ratio on the market
• Rigid fully triangulated design is rigid enough to withstand years of abuse
• The only K member on the market with a lifetime warranty. 
• Geometry revised to increase:

  -Caster (increased positive)
  -Camber (increased negative)
  -Ackerman (toe out in turn increased)

• Bumpsteer improvements
• Increased header clearance
• Ease of engine and accessory maintenance
• Modular design and manufacturing allows for custom ordering of models for engine swaps, solid engine mountings or for motor plate applications.
• Easy to install
• Excellent fit.

Although a Griggs TorqueArm and Panhard Bar accounts for a large percentage of handling improvement there comes a point at which the factory front suspension geometry becomes the limiting factor in overall chassis performance.  This can only be properly corrected by changing the K-Member to the GR40 geometry. 

The revised Geometry that a GR40 K-Member provides reduces brake dive because the braking effort is focused through the cars center of gravity rather than below it which happens with stock geometry and lowering springs.  By relocating the control arm pickup points relative to the stock location, the dynamic camber gain is increased.  It is important that more negative camber is required as cornering force increases.  This is due to increased tire deflection and body roll which diminish the tire contact area.  The K-member will increase dynamic camber change (during body roll).  Increasing dynamic camber gain means less static camber needs to be dialed into the suspension, allowing more tire contact during straight line braking.  It will also improve straight line feel and driver confidence.  We also make changes to the cars steering effectiveness and feel through fine tuning the Ackerman (Ackerman is the increase in toe out of the front tires as the steering wheel is turned due to the fact the inboard tire is rolling through a shorter radius then the outboard tire.).  Through changes in the K-Member geometry the wheelbase is also lengthened and front to rear weight distribution is improved. 

The GR40 K-Member is the heart of the front suspension system.  Besides providing improved geometry the tubular K-member is a big weight savings and a joy to work with when installing headers and such because of all the room it leaves open.  Modular engine units all have relocated motor mounts to provide clearance for large tube high ground clearance long tube race headers  (Insert Link for Headers Page)
