strut bars (upper tie bars) don't do much for a car until the suspension has been heavily stiffened. That being said the right thing to do is to dump the rear strut bar and get that front sway bar upgrade.

yah bro i dont have a rear strut bar, i have a front strut bar and since i didnt really feel a difference, i wanted to ditch that and get the front sway bar to complement the rear sway bar.

i'm not a big fan of strut-tower bars. somewhere i read that generally speaking most production cars have "stiff enough" chassis. the wrx being no exception.

a lot of posts have been made about benefits of front anti-roll bars specifically with the wrx. it will decrease loss of grip due to camber gain, or said another way, reduce camber gain in the front giving more grip.

i have finally had some time and good weather to try out my cobb anti-roll bars. the rears are set soft. i've whipped around a few corners and round-abouts and have noticed the different behavior of having a stiffer front bar.

what sticks out in my mind as an example of the different feel is this: when i first got the wrx, i took it about town in a steady rain. i got about 1/2 through a left hand turn on any normal city block, and, in second gear, punched it! what was so great is how the car lurched forward (going off the radius of my turn) and then it seemed the front-end swung right back into the turn. it was really quite fun.

in the recent corners or round-abouts in dry pavement, i've started to notice the same type of feel. that the front grabs more and keeps me tucked into the turn.

EDIT: i can't say what will happen when i increase the stiffness of the rear bar (to the middle of three settings). i think the overall roll stiffness will increase quite a bit more, but i'm not sure about the balance. in theory it'll shift towards neutral or oversteer. but i think the overall grip (the whole car) will increase and i'll be able to corner faster.

A lower arm bar like the Cusco Version 2 or the STi lower arm bar will make a much larger difference than a strut tower bar. You'll feel the increased rigidity immediately with a Cusco V2, and you'll be able to measure the increased grip with a g-meter, but nobody will be able to see it when you pop your hood.

i love my strut bars but i arlready have a rear sway and springs. i think every bit helps to stiffen the chasis. i do think that sway bars should come first tho. and if u get a strut bar get one thats one welded piece, like the cusco ti, carbing bars.

I'd say lose the front strut bar for the sway bar. A strut bar will do little to nothing unless it is triangulated.
