Is there any data supporting the addition of the side bars? I can see the necessity of the lower stress bar side-to-side (Camber), but there is already significant bracing against fore/aft (Caster) movement.
I've dismantled the rear suspension when I did my tranny work and personally, these side bars appear to be overkill in all but the most extreme track use (I do not incl. Auto-X or DEs).
I have the Mantisport 'Ernie' bar and noticed improvement (not extreme or significant, but definitely improved), + Fr/Rr. Strut Tower braces.
Can someone show me some data that this area requires additional bracing, because I'm not convinced that the side bars are a necessity, or even a positive addition. There's no benefit to over-strengthening something which is already strong enough to do the job.
