Does anyone make one for the LS???

it already has one. But quik made his own that is mounted to the strut tower. If you remove all the black plastic in the rear of the engine compartment you will fill your brace. It serves double duty as a sway abaitment system and a place to mount things like black plastic. :)

right - the LS already has one - but you can't see it (tucked under the plastic cowl).

Here's some threads on it:
