a longer wheel base sure but not going wider.
taken from a racing wiki about steering components
Wheel spacers are installed between the hub and the wheel and push the wheels further away from the chassis, widening the track. This in turn increases the amount of grip that your vehicle has in corners, allowing faster cornering.
however it is more hard on the steering components and take more power to turn but it will turn sharper.
no different then me spening over 2k+ on my quad to add the extended racing A-arm's for better steering and stability.
picture your 2wd truck with clod wheels on the front and some 2.2's on the rear and what kinda cyclones you could pull off.
another example in a reversed orientation picture a drag racing rail setup as they are not setup for tight turns but extend them front wheels out 3-4 feet per side and that long rocket will cut corners alot better.
