Steering

Longer wheel base larger turning radius.

And better ride comfort.

Shorter wheelbase is less comfortable, but better for performance driving/racing.

where is the approximate radius, is the wheelbase, is the steer angle, and is the caster angle of the steering axis.

If you mean "Can I change the wheelbase? What will happen?" That is a different question with different answers.

If you have ever owned a Jeep CJ5 you would know. The common term is " the CJ jitters". A high center of gravity with a short wheel base combined makes for total attention needed at highway speeds. First time i drove one i nearly flipped it on its side at around 35 mph.

The longer wheelbase has a "slower" turn (larger radius) and softer ride also applies to bicycles as well as autos. That's why cruisers are long since quick turns aren't an issue where they are ridden typically and have a soft ride (relative term as a full suspension bike tops a rigid bike no matter what the wheelbase is)while road racing bikes have short wheel bases and are very stiff no mater what material the frame is made from, as your typical roadie geek wants the lower parts of his torso beaten into numbness just so he can sail down twisting Alpine passes at 60mph plus on average. (and believe me, the numbness does occur in some very sensitive parts)

If a cars wheel base is altered the "Ackermann" angle will be wrong causing the front wheels so skid when cornering, causing more wear on the front tyres and losing some grip while cornering.

Google Ackerman angle at wikipedia!

It is for this reason I asked the OP if this is what he meant. See #4.

Smaller Base can negotiate a short curve or turning, with short radius. This will be very much experienced or seen while travelling or driving on a hiily track or mountain.
