I was going to say about the same thing, but you said it better Ti.

I have essentially the same setup as you do Dave, except I have an Addco
rear bar.  I bought it many years ago and with the stock front bar, the
car seemed to push more and had a very uneven step from understeer to
oversteer.  After I did the 4kq front bar, it took me a couple months to
remember I had the rear bar.  That went back on and the car is way fun.
I can still get it to push, but I have to pitch it pretty inelegantly to
do so.
