which offset would work better on gsr with 1.5in drop with 16x7 wheels? +40mm or +45mm. Thanks

 

Tire profile also matters. With 205/45 you should be ok with either 40 or 45 offset since you arent dropped a lot. With 215/45 like the Azenis, the best offset is actually about 42-43mm. You can go 45mm and get some 2-3mm spacers if it ends up rubbing on the inside or get the 40 and see if you have to roll the fenders to clear the outside.

 

would I be able to fit 205/55's with either one?

Very good advice Tilt. I have +40 16x7 slipstreams and plan on running the 215 azenis one day. I couldn't get the steel grey in a +45. I went with the +40's and will probably have to roll the fenders to get them to fit. Planning is key when it comes to expensive things like wheels and tires.
