If by 'track' you mean road course, UMI makes rear LCAs with a poly bushing at one end and a spherical of some sort (Roto-joint) that is not a rod end at the other. That design is much better suited to cornering than any of the garden-variety LCAs that use poly at both ends. Spohn, with their Poly/Del-Sphere LCAs, being another.with what stuff should i install my handling pack? Like what brand of control arms and panhard bar. Im serching something between track and street use.
