It was hitting curves, weaving traffic, accelerting more quickly and stopping faster. I assume the difference in circumsference and rotational mass was the reason. Diameter is the same but circumsference can't be with different size tires.
The biggest problem is that look. That look is just too darn cool with staggered. Since we aren't tracking the cars, the performance difference just isn't enough to compensate for that look. That's it and only it. No need to talk about performance. The slight difference isn't enough to forego the LOOK!

But we are both kidding ourselves to think that the 3GS could actually handle being pushed hard enough to understeer. The suspension is floaty even with coilovers set to the max and the steering feel is non existent
