Ok, guys... this a known problem in DIRT, the lag (delay) in quick steering inputs is one of the complaints of many users with wheel-controllers and it's yet to be adressed with either an official or a 3rd parties patch.
There's a solution for similar problems with other racing-sims and it works great in DIRT.
...note that it won't solve the problem totally though.
For that, I suppose one would need at least 36fps all the time, which is a bit difficult with such a heavy game on resources like DIRT is but it will definitly help a LOT.
The solution is to have pre-rendered frames set at "0" (default is "3") in your graphics-card driver options.
How to do it...?
If you have a Nvidia graphics-card, you'll need either NVTweak (http://downloads.guru3d.com/download.php?det=911) or Riva Tuner (http://downloads.guru3d.com/download.php?det=1264) or nTune (http://downloads.guru3d.com/download.php?det=1675) or Nhancer (http://www.nhancer.com/) to unlock various extra options in the driver options (in the Nvidia control panel/driver in case of NVtweak, RivaTuner, nTune and Nhancer have their own separate controls).
If you have already installed one of these programs, you just have to change the value of the PreRender (in Direct3D options), the default value is "3" (three), if you reduce that value to "0" (zero) you'll have improved response from your wheel controller in game, the steering delay will be partially fixed.
If you have an ATI graphics-card, you'll need ATI-Tray-Tools (http://downloads.guru3d.com/download.php?det=733) (some optimized drivers such as NGO have it included), to unlock various extra options in the driver options (ATT has its own separate controls).
If you have already installed this program, you just have to change the value of the Flip Queue Size (in Direct3D options), the default value is "3" (three), if you reduce that value to "0" (zero) you'll have improved response from your wheel controller in game, the steering delay will be partially fixed.
Remember, this will help a lot to get rid of the wheel lag but it's also impossible to have an instant response without good frame rates (+36fps all the time!), so having the game "tweaked" and with correct options/settings to achieve that is just as important.
Having the latest drivers for your graphics-card is really recommended.
Latest version of DirectX9.0C (current is DX_August'07 (http://www.microsoft.com/downloads/details.aspx?FamilyID=CB7397F3-0949-487B-9247-8FEE451BF952&displaylang=en)) does help for a smoother gameplay, so this is also worth the download and installation. ;)
As a last (personal) recommendation for steering-wheel users, decrease the steering-linearity to negative values (I'm using -20%).
PS: ...we definitly need an option in DIRT to disable shadows in track objects, or at least make them non-dinamic (static). :-/
