sod the house
i fitted a whiteline rear sway bar and it makes a difference. i have only tried it on soft which is about +45% i think (i did work it out but cant remember off the top of my head).
i didnt do the front yet as its a subframe out job.
personally i would spend the money on shocks first before ARB's. the ride is class on my car now.
I had Eibach ARBs, Weitec coilovers, S3 brakes, WALK etc etc on my A3 and the ride and handling was awesome. I also had Goodyear Eagle F1's on by then which are light years ahead of the RE050A's. I sold all of the mods as they were a couple years old and I would prefer new stuff on a new car, but I'm too tight to buy it all again.

I'm pretty happy with the ride now it's just really large bumps/dips in the road which unsettle the car a bit, but by then I'd be going faster than I should anyway so it's time to slow down
