K-Member Selection 7 K-Member Selection

Our K-Member is the foundation of the Griggs Racing front suspension system, providing the correct geometry, with superior rigidty and the highest strength to weight ratio. For 40 years we have continued revising and improving our design as tires, downforce and brakes have substantially increased loads and demand on the K-Member structure.

Motor Mount Selection 8 Motor Mount Selection

We offer both Soft (Elastomer) and Solid (Aluminum or Steel) motor mounts depending on your usage. Solid mounts reduce movement of the engine and transmission assembly, increasing shifting precision and a degree of increase in chassis rigiditiy.
If you have a properly balanced engine assembly, including flywheel and clutch, solid mounts can be used on the street, although you may feel minor harmonic vibrations at lower RPMs (for V8 engines, this is usually around 2100 RPMs).
