GT3 Lower Control Arms (LCA)

996 and 997 GT3 cars came equipped with adjustable type lower control arms fit to the front of the car. This two-piece design allows the fitment of shims between inner and outer halves, enabling the control arm to be extended. This has the effect of both increasing camber and widening track width, increasing cornering grip and performance.

There are two flavors of factory GT3 LCA:
– GT3 Street Lower control arms have a rubber central bushing and is paired with a rubber inner
– GT3 Cup Lower Control arms have a solid caster-adjustable center bushing and is paired with a spherical bearing inner for added performance, control and precision.These same GT3 lower control arms can be fit to all 996, 997, Boxster and Cayman cars through 2020 to both the front and rear. They can also be fit the front of 991 cars.

This a great performance upgrade allowing increased camber, track width and performance.

The GT3 lower control arm is a system built up of three or four component parts, each ordered separately.
– GT3 lower control arm outer
– GT3 lower control arms shims (various thicknesses, stackable)
– Litronic bracket
– GT3 lower control arm inner
