Reducing the offset with spacers increases the track. A wider track means less weight transfer during cornering which in turn yields more total grip. As jmg pointed out, changing track width differently front and rear will affect the handling balance of the car (over/understeer).
Changing offsets also aters the wheel to spring/damper movement ratio, which essentially changes the effective spring and damping rates. Albeit by relatively small amounts.
IMO, the biggest negative drawback of changing offsets is on the front axle due to the effect on scrub radius and required Ackerman angle when the wheels are steered. It can adversly affect steering feel and feedback and reduce front end grip due to increased scrub (and consequently increase front tire wear).

So with that said if you go to just a wider wheel does it have the same affect on suspension dampening? Thanks guys great information
