Been thinking about upgrading my PSK bar for H-sports, but after some research...
I'm considering leaving the front stock and doing the RS6 bar in the rear. For reference, my stock bar was 15.25mm, PSK 18mm, RS6 22mm, H-sport 24mm.
Here is my issue: Since our cars inherently understeer, why increase the diameter of the front and rear? They would both offset each other, and you would still understeer into turns. Does it not make more sense to increase the rear only, there by decreasing understeer?

your after market suspension isn't "stiff" enough to make that change
in understeer. You're essentially just stiffening the rear by just upgrading the rear to an rS6 sway bar... which will still give you more oversteer.. offset it properly with the H-sport bars front and rear or RS6 bars front and rear or PSK bars front and rear.

I took off my front H-sport and reinstalled my stock sport sway bar just a few weeks ago...
I don't know why I put that front bar on in the first place. I left the H-Sport rear bar in at the "hard" setting.
Car definitely has improved turn in (feels more progressive and more noticable at speed), and feels more neutral in the turns. The test for me was Sears Point, where the handling impressed me and the tail came around nicely. Even an early apexer like me noticed significantly less push.
Anyhow, I'd recommend the setup. My canned response to future H-Sport posts will be "install the rear on hard, leave the front alone."
Anyhow, FWIW....

A larger rear bar will delay the onset of understeer. A BIG rear bar will
contribute to a "snap-oversteer" situation.
I put the PSK rear bar on my stock '00 2.7T. The rear end was more firm in it's behavior and ride. The results were a reduced/more controlled "sway" action from the rear, producing a better ride for those in the back, and a slight lessening of speed-induced understeer. You can also reproduce this effect by raising the rear tire pressures to about 3-4 psi MORE than the fronts. You might want to try that before you go to the effort to change rear bars.

As it's been said, if you get to big, you will have major oversteer that can happen at any time...
makes me think of my old 5.0 Mustang! I haven't STF, how many are running the RS6 rear bar??
