Hell yeah! it works!
don't expect anything while cornering in indifference....
you have to get to that point of speed while cornering that the body frame gets "loaded" and then you feel it.
of course i can't measure how much, but you feel a difference in the car's response.
at first you feel the front end being slightly indefferent (even slightly understeer) like it is stock and then when you reach the frame "loading" point while turning, there is something like a small

when the brace starts working. front wheels kind of stick down to the ground and the feedback you get from the steering wheel gets better and better. the slap i m talking about is improved traction of the front end and then this helps the traction of the rear end. so prepare to re-learn how the car works now (i had the same experience with the DDM backbone and probeam and HR springs).
beware of the handling of the steering wheel coz stepping from the LV brace-does-not-work phase to the LV brace-is-now-working phase may need you to make small adjustments to the steering wheel angle (just a click less turning). but this is the essence of driving the kappa with suspension upgrades: using the steering wheel to control the car more accurately
combined with a DDM front brace (to get the front suspensions working better as a team)- (while LV brace improves the rigidity of the body frame) it will give a front end like it should be from the factory: obey any orders, improve handling, better traction.
i highly suggest to use it in combination with at least the probeam (also adding the backbone is even better).
Pls note that i have Probeam, backbone, LV brace and HR springs, so i don't know how it will work without these.
Good job LV! (hope the bolts can handle the load

)
