What kinda benefits can I reap from installing thicker bars?
Will thicker bars make my car ride stiffer? What I am looking for is flatter
cornering but not into rock hard washboard ride?
What about bilsteins shocks? Are they good?

thanks

It doesn't affect ride quality in the same way stiffer shocks/springs will.

There is a danger if you put too thick/stiff bars in some of the cars, as people have had their subframes crack. I used the Audi OEM sport bars in my '96 a4q. $200 for both bars from my dealer (Heishman's in VA) with the 15% QCUSA discount. Clair Audi (advertiser here) offers the same prices I paid.
