Hotchkis or Bilstein shocks

I would say the better comparison is the progressive improvement instead of a Brand X vs. Brand Y question. There are more people with experience of the Bilstiens, so when you ask this question, the results will reflect that.
That said, how many folks that have made the jump from Bilstiens to the Foxs and love the improvement? I'd dare to say all of them. I haven't seen too many folks complaining about their Fox shocks and looking for a set of Bilstiens to put back on the car.
It's like going from BFG Radial TA's to Falkens/Nittos/Dunlops, you can't tell the difference until you drive on them, but once you do, you'll never want to go back.

Look at what the fastest cars are running...
