lol i just wrote up something on this 2 mins ago.....
well i had just installed a Whiteline 22-24mm AFSB and having similar experiences. my settings on my bars are at 24mm in the front and 22mm in the rear.
i should mention that i have Tein Coilovers, Tein Front strut, Whiteline front and rear sways(with endlinks), and 17x7 Toyo T1R's, Work CR Kai wheels
what alot of the concerns about having a bigger bar in the front will cause understeer, and this is true to a certain extent. it will cause understeer but ONLY AT THE LIMITS. and since the limits of what the car can do have been raised, this is only a problem if you are pushing the absolute limits of the vehicle. ( got from NASIOC)
However my experiences after the 1st test drive is that the steering felt heavier, but still very controllable. However for the understeer "problem", i barely experienced that at all. for general agressive driving i actually found that the car was more nuetral and was able to take the lines where i wanted. And if i took a corner near or at the limits the front tires would start to hop and skidd across. now this got me thinking on how and why its doing this, but i liked it.....simply because AWD will allow the fronts to slip but the rear power will push the car though the corner. and really reducing my understeer but still some present.
