Yeah, there would be some under-steer, more or less depending on how big the difference in contact patch is front-to-rear.
My biggest personal concern is braking and front-end grip. I don't like under-steer, and I can deal with the back end losing grip before the front. But I do want the damn car to stop as quickly as possible.
