a lot of guys here run:
8.5 front and 9.5 rear, or
9.5 front and 10.5 rear, or
8.5 front and 10 rear...

anything wrong with 2 inch or more stagger difference???
for example, 8.5 front and 10.5 rear

some aftermarket porsche wheels run 2.5 inch stagger: 8.5 front and 11 rear...

so what are the cons?

 

I think the biggest con is oversteer. Our cars already have this tendancy and if you stagger the front and rears even more you'll just amplify it to some extent.

 

you meen understeer right??? The front grip on the Z will give up before the rear and adding more rubber to the rear will just make it worse...

 

Really? Maybe the G35s handle a little differently. I've never lost grip in my front 2 tires, rear tires however a lot.

 

You might be inducing under steer.

 

Find an empty parking lot. Drive 50 mph. Make a hard right or left turn.
