I think it is not possible. The pitstop time is related to what the crew has to do, so tyres change and refuelling, and some fix (a new nose cone...). Bye Claudio
The Pitstop time was 8-10 seconds for anything you had to work on the car. For V1.13, this was corrected, and if you've to change a nosecone or replace anything it'll take you longer. But I don't think this is changeable. Sorry, because I had quite a similar idea some years ago.
