I have a 90 n/a rx7.

My car is 5 bolt for sure, is it 5x100 or 5x114.3?

Also, what kind of offset do i need / can i use? I am looking at getting 16"'s or 17"s.

Thanks

 

Please read the FAQ for FCs at the top of this forum..this and many other common questions can be answered there..

The wheels are 5x114.3, and are 40mm offset stock.

 

Ok +40 offset is stock, can i use other offsets also? or just 40

 

You could use other offsets, depending on wheel width, etc.. If you are staying with a 6-7" wheel, stick with 40. If going with a wider wheel, you will need a lower offset, 35-38 ususally, but it all depends on the specific wheel and application.
