It depends on what you want. The bigger the rear bar, the better in terms of overall grip, but worse for transitions. Your car will tend to oversteer (like in my sig), so you'd better be very comfortable with it's setup, or just don't push it.
I have the S3 suspension and the hotchkiss bars. The rear bar is massive compared to the front, but there is enough damper adjustment in the suspension to tune out the oversteer reasonably well. On the street, I have them adjusted about halfway in terms of oversteer (full soft front and rear).
