I'm about to put my rear flares on my Z, I could go with rear spacers. Right now I have 19 by 10 Piaa Super Rozza
MY question is if I do spacers for now, would it will be a problem later when I get the wheels.. will the wheel sit in the right place when I take off the spacer,
I plan to do 20 by 12.5 in the rear.. but I have to do spacer now so they could put my flares..

 

Offset specs kinda help.

 

offsets would help alot and so would the size of the spacer your putting on.

 

That's the thing on my PiAA wheels I have a big lip and i'm trying to get a bigger lip on the new wheels, I'm new to this don't know much about off set - or + off set that's the reason I need help. to get a bigger lip what off set I need?

 

If you run spacers, and get different wheels, you can either keep the spacers on the car or not.

 

Ones my wheels come in I want to take off the spacer cause the wheels I'm getting are 20 by 12.5. I have 19 by 10 now what sizes spacer do I need to push out my wheel so it will fill the space I did the rear flares V3 on my Z just the rears.. I need to push my wheel out.. some one told me 15mm another person told me 25mm from Ichiba Hub Centric version 2..

 

Ok 19x10 is your wheel size, now what are your offsets?

 

Don't know I got the wheels uses, the ones that I have on there now. They are the PIAA SUPER ROZZA 2pc. for the non brembo Z.. I have a huge lip on the back but with the new flares it won't reach, that's why I need help for what sizes spacer I need to push the wheel out so it would be even with the flares..
I know I'm a idiot, I need (spacers for DUMMIES) book. I hope you can understand what I'm trying to do..

 

The specs would usually be posted on a tab within the wheel saying like "19x10 +18"

if I remember from a post by motormouth, 1" = 27.5mm... so if you're making up about 2 inches of lip would be a pretty considerable size spacer unless they are negative in offset. (negative pushes the face of the wheel towards the axel giving deeper lips)
