It needs the brace, you don't.
Our Bonne'* have a much lighter engine. Check out the weight of the new GXP....3,940 lbs.
That'* about 140 extra lbs of engine weight over those front wheels.
Also note that the new one only pulled .79 g on the skidpad.
The 00 SSEi pulled .81 g stock without the strut bar. :P
I really didn't think the newer +00 models needed one because the firewall meets the strut towers right at the centerline instead of further back like the older models.
