It does cause input lag but it's there to stop screen tearing when you have an FPS higher than the refresh rate of your monitor. By capping your FPS with VSync it's just slowing down the amount of information sent to your PC because before the frame can be drawn it has to know all the information from your controller etc and it can only check for changes in position or for button presses every 60th of a second (if it's capped to 60 FPS). This is from what I've heard it could be wrong though.
There is an option though in iRacing to cap your FPS without VSync.
