Typically, the wider the tire up front, the less it has a tendency for understeer.
The downside is that your low-speed manuevering (think parallel parking) requires 'Ahhhnold' type work on the steering wheel due to the increased rolling resistance.
Street cars typically have inherent undesteer for a reason.
A totally 'neutral' car will tax the skills of an ordinary driver.
You really have to work (all the time) to control a 'neutral' car, and if you don't... or can't, it'll get away from you with little warning.
