The difference in track between and S2 Elise and a Vx is about 10-15mm (Elise is wider) but I figured this would be down to wheel/tyre combo rather than subframe/chassis. Yeah, no.
The following is the sheer support rod from SSC's rear toe control arm kit. Meant for an S2 Elise, everything else fits up perfectly, but the dimension between the chassis mounts is clearly quite different meaning th sheer rod need to be cut-n-shut to fit the VX. Not a big drama, but a stumbling block none the less
