Does anyone know if the 997 GT3 TRW LCA (JTC1190 & 1191) fit on either the front or rear? They are listed on the Summit Racing site as rear fitment. But from what Ive read the front and rear LCA are interchangeable. Is this correct? Anyone use these on the front of their car?

These would be going on the front of a 997.2 C2S to gain around 2.0-2.5 degrees of negative camber up front.

Not positive but I thought the height of the center rubber puck is different on the 997 front to rear. Use thick washers to shim it. Or replace the front thrust control arms with the 996 version.

I think the washers are needed when using 996 GT3 control arms, but it’s not clear about the 997 GT3 arms. Most kits available are made using the 996 GT3 arms.

The 997 carrera's front arm has a "hydraulic" bushing and is thicker than the 996 and 997 gt3 arm bushing. The corresponding diagonal/caster/thrust control arm has a larger "fork" to accommodate this bushing.

If washers are used, can the 997 GT3 lca fit a 997 c2s? Like they do for the GT3 996 lca kits?
