hey does anyone know if rota slip streams, 16X7 all 4 with offset +45 all around will fit on our cars? im not planning to lower my car so i dont think i have to worry about rubbing, but do you think it will fit on ap1's? i have found some slipstreams with azenis tires for 300 ONLY so if this works than i'm gonna buy it. thanks for all the help!

 

I ran 16 X 7, 44 offset and staggered winter tires for years. They'll fit. No rubbing, but the handling will suffer because of the staggered tires on non-staggered rims. If you run the same size tires all around, the handling will suffer even more.
Oh, this is assuming the bolt pattern is 5 X 114.

 

xviper is correct. They will fit with the correct size tires but I would not recommend them for handling.

 

so what size should be on the back? and on the front do you guys reccomment the most? thanks for the help guys!

 

What size "what"? Rims or tires?
If it's rims, you didn't say you had a choice of a different size for those rims. You seem to indicate that "16X7 all 4 with offset +45" was all there was for a choice.
The "correct" size would be what the OEM numbers would be.
16 X 6.5, 55mm offset front with a 205/55/16 tire.
16 X 7.5, 65mm offset rear with a 225/50/16 OEM tire or a 245/45/16 non-OEM tire.
