Brembo BBK didn't fit my 17" stock rim!
 

Today, I trying to put the Brembo BBK, but my 2001 maxima 17" stock rim didn't fit. The rim didn't have enough depth to put the rim backon.

Any suggestion, may 18" rim?

It is because your stock rims have an offset that is too high. You need to get either spacers (cheap) or new wheels (expensive). The choice I leave up to you.

Can you please tell me where I can get a spacer or if I buying a new wheels, what size is the offset?

Thanks

check local auto store. See if 5mm will work. Anything bigger, you'll need to buy longer studs.

Like ammi said, you need to figure out how much space you need. If its less than 5mm you can just buy one of those, but if its more you will need longer wheelstuds to go along with it. I believe the H&R spacers come with longer wheelstuds.

The 5mm H&R spacers do not come with new studs, they re-use the ones on the car. 15mm and larger spacers do indeed come with new studs.
