You can get B6's or B12's on Rockauto.com for a bit cheaper.
I personally have B6's with a Steeda progressive springs and Whiteline adjustable sways bars. I love it!
I have a problem, when cold, or randomly, when taking off in 1st gear, it completely falls on its face then comes back to life. When I'm full throttle, it shift slow when at 7300rpm.. starts nosing over then shifts.
