Does anyone know of any shops in the Northern VA (Arlington, in particular) area that does installs for performance parts? I was thinking of swapping out my Clutch Delay Valve for a "new" one:

If they do a good job with the CDV, I was thinking of some more substantial upgrades (shocks, brakes, etc). Thanks!


I have a 2002 330xi.
