what do you guy think of this i'm getting 19x9.5 and 19x8.5 with 265/30/19 in the rear and 235/35/19 in the front. Also i'm dropped on Eibach Sportline

 

First of all weight is everything w/ tires and wheels.
So if you are set on 19's than:
A 235 will fit on a 8" to 9.5" wheel and a 265 will fit on a 9"-10" wheel. If these are you tire sizes than I would go with a 8" and 9" wheel sizes to reduce weight.
If you are sticking with those wheel sizes than go for a tire combo of:
245 front and 275 rear, these fit nice on the Z and have been proven to work with VDC.

 

that the tire combo i had with my 18's that were 8.5 and 9.5 but i want just a slight streched look

 

why? look better that way? your combo is ok. Typical size is 245/275

 

bubble are you saying that they look better stretched?

 

no.
