I agree w/Doug...have them valved to your specific set-up/specs either by Bilstein or by a shop like Smart Racing. I'm planning on pulling my Sports this winter and having Smart Racing revalve them after I add larger sways.

Also, you may want to consider going with larger torsion. Many find a 22/28 combo a good street/track compromise. I went with 23/29 torsions and 22/21 sways with Bilstein Sports and while the ride is firm, I think it is ok for the street, especially if you have stock seats.
Just my 02 cents.
