07 touring and going to run with 8.5" +20 up front and 9.5" +20 out back. Will I need spacers for flush fitment and if so what size?

 

Yes, at least 25mm

 

for both front and back?

 

How low are you? What size tires are you going to be running? Why not get wider wheels?

 

omg make it stop

 

hahah I know, this dude has made 9 threads about his wheels already. You should have made one thread titled "multiple questions about my new wheels.", or you could search the 1000's of other wheel threads with similar specs.

 

Lulz---Searching is hard. Now having OTHER people search and tell you is the way to go

 

at this point i am totally confused as to how everyone is unable to just diy...
fitment and look is a personal thing. there is no "one" way to make it perfect.
20" wheels to start on a z is just fail out of the box op.

take a step back and think about what you want - 20x8.5" wheels are a JOKE.

 

^yeah you gotta get 20x7.5

 

i hope he doesn't continue asking multiple questions when he decides to get suspension, bodykit, brakes etc. lol

 

I'm so glad I sold my Z

 

sorry, they arent 20 inch wheels. They are 18" and +20 is the offset...

 

You could just buy the right offset wheels to start with and avoid spacers.

 

Man bunch of haters. Anyway. I just put 20 mm spacer on my rears. Nismo lmgt4. 18x9.5. Forgot offset but I think 25-30.

IMO. I think it's too much. I want to try 15mm. Tires stick out way too much for my taste. And I listened to posts from here. 275mm rear tire btw

 

I would start with different wheels, if you want the flush look start at nothing smaller than 9.5 front and 10.5 rears with offsets no higher than +15

 

You made a thread with the exact same question thats still on the same page . If you want to figure out where your wheels will sit look around at others set-ups.

 

Yes. Front 20 mm. Rear 30 mm.

 

I'm running exact same setup on my G but with 19's. I have 20mm all the way around at +5 & still not all the way flush. I would go 25mm all the way around lik "Jduet" said earlier.
