Couple things about a narrow track front end
You loose some stability or outrigger effect with it being narrower. If the car gets out of the groove/crossed upped, then the recovery angle gets smaller (tipping effect) compounded by not being 300" of wheelbase. The wider the front axle on a short WB car acts as an outrigger putting weight on the outside tire(of the turn) keeping the car flat at an increrased angle and makes the steering input not have to be as violent into the recovery. In other words a wider front end slows things down for eaiser control on a short wheelbase chassie when things go wrong.
Prefer rear steer over front steer, it just looks cleaner. If you run the steering rod out to the left front spindle then steering arms in front or back does not matter, but if you use a bellcrank then it does
