you will be disappointed when you mount these wheels...they'll be too tucked in

 

.

 

these are the worst wheel sizes I have ever seen.

 

you'll definitely need some spacers with those offsets

have no idea if you'll rub though.

 

Those will probably not clear your BBK depending on spoke style. You will need 25mm spacers just to get them out where they should be. I know you got them cheap but dump them for something that is made in correct Z fitment.

 

If you have a BBK, get some good wheels cheapo

Why the hell to people buy first and ask questions later. Just so you know, those will look retarded on your car. Good investment bud.

 

Use a offset calculator to compare your current wheels to the new wheels. With the new dimensions, check the car with a tape. Do you clear the suspension, brakes calipers and fenders? Reference: http://www.1010tires.com/WheelOffsetCalculator.asp

 

Through no fault of my own I'm running a similar setup, and now, thanks to some thieves the wheels are bent and two tires have a slow leak. It looks awful. Stick to 18'' or 19'' and if you insist on getting 20's at least get them really wide with good offsets.

 

20x8.5 +38..sounds like a very cheap(probably chrome) wheels..
I'm sorry man, I wish you had asked us BEFORE you made the purchase.

+1 Uneducated, lazy to search Z owners and their WRX offset wheels in SUV diameters FTL!

 

please, for the love of my350z.com, dont put those horrible things on your car.
