I know this has been beat to death but I have seached and can't find the answer

I have bought Stern ST2 19x8.5with 20 offset all the way around

Will I need Spacers? if so how big front and back

ohh I have 2006 coupe non-brembo application

Sorry again just need a little help

You don't have to search your exact wheel brand to see if you need spacers, anything 8.5 +20ish would give you the idea.

And no, you wouldn't "need" spacers
