Need answers to questions about rim offset!

Hey guys I was shopping for rims and don't know much about rims fitment and offset and spacers and stuff like that.

Can someone tell me which offset I need if i wanted 17x7.5 5x100 rims? Will these fit? Why or why not?

I might also look into XXR 526 or 006

The rims I'm currently looking into are Drag DR19 black gloss/machined face
They say they are 45 offset, 17x7.5

Feel free to comment about them and tell me how they look laugh (I drive a carbon mica blue 2002 Celica, its basically black at night and a hint of blue in the day)

Thanks for any help smile
