Changes to player speeds?

I am launching this thread to create a place for people to talk about mods they have made on the player ship. Specifically changes they made to speed or acceleration and the gameplay that resulted.

Almost everyone has a modded set of values. Perhaps you removed the lateral thrusters. Perhaps you removed the speed caps on AI ships. Perhaps you decreased top speeds to a crawl. I would like to hear about them. Did you like them? Or hate the change?

What values did you use? So that others may give your ideas a try.
