As an example, there is this nasty area in the "left turn pocket" at one of the intersections near my home where I frequently need to stop on a red light. With stock wheels and tires it's just annoying, but with wider tires on lower offset wheels (et37 in my case) the steering wheel tries to turn left because of those bumps, so I have to hold it while stopping the car.
On the flip side, I know people who have successfully tracked cars with et30 effective offsets and set some very decent lap times :P
Depends on the goals. Not a bad idea to increase the front and rear track equally vs stock, or you can fine tune the balance of the car by using different wheels or spacers.
That being said, perhaps a better strategy would be to maximize grip by maximizing the track width on both ends individually (depending on the regulations, geometry of the car and suspension, tire size, scrub radius considerations, etc.) and then fine-tune the balance with anti-roll bars.

Thanks! That all makes a lot more sense now.
So the drawbacks from a slight change in scrub radius are offset by the benefits of running a wider track (more grip), correct?
That means it would be more beneficial to run the lowest allowed offset (+41) at the front and rear and fine tuning with sway bars?
Just want to make sure I'm understanding correctly.
