For your question, to be better understood by us simple people, it matters if you want to "same height front vs rear" of the wheels' axis to the floor, or fromt he wheel's axis to the wheel arches above them.
If it's the wheel center to floor; then it's easy: only 1 factor influences it and that is the rubber tire. As the diameter is equal, the thickness of the sidewall will determine where your wheel axis is. A good tire shop will be able to help you out for sure.
If you're looking to get the wheel arches at the same height front and back, then there are a lot more aspects to cover: your springs, Alu spacers up front yes/no, rubber spring perch in the rear with 1,2 or 3 dots, to name but a few.
Also, read up on this thread, it may help you already a bit:

@Candia4441 the more important question is what the offset of the wheels are. this discussion has been pounded thru numerous times on the forum and with you ... we have provided you with further insight in understanding offset in relation to wheel width. thanks @eriknetherlands for posting a link to my FAQ on wheel + tire sizes / options. the fight on the coupe is to keep from hitting the fender lips with the tires as well as hitting the springs / struts. a 7.5" wheel on the front may fit but is more likely to hit the strut with a 16" wheel ... depending on the offset, the tire might hit the fender lip - you will need a different offset that et 11 (which is the offset for a 7" wheel). you will probably need about et17?
the standard size wheels for 16" tires is 205/55-16 front and 225/50-16 rears. look up tire specs on tirerack.com and check out the wheel width variables for the given tire size.

Hello,
thank you for explaining, my wheel is clearing by 4mm from spring but I have to roll the fender to clear I did not know what is the right height for the tire now if original tire for 16" wheel is 205-55-16 the height is 24.88" (631.9)mm and side wall is 4.44(112.75)mm now I have to choose rear 9.5" wide tire to be a same height and that was a problem for me didn't know right height.
225/50-16 is the same diameter as the 205/55-16. this is listed in the referenced FAQ.
see below for a screenshot from tirerack.com. the 9.5" rear is going to give you trouble with the 225/50-16. there aren't a lot of wide 16" tires - i have included a pirelli p zero rosso in 245/45-16. the tire section width is 9.5" and the rim width range is 7.5" to 9". i think you are going to have all kinds of problems with a 9.5" rim on a coupe.

thank you again, I choose a 245/45/16 for rear and 225/50/16 for front I have a E46 engine and Wilwood big brake system I hope all this modification will work right the reason back rim is to wide thats how it came it is epsilon wheel that I restore it it is very nice wheel I look all around to fine a drum 9.5 is to wide but I couldnt fined any I hope that will not give me a problem if it dos I have no choice to spend another 3K for BBS
good luck, don't think the 225/50 is going to fit in the front. you better tightly roll the fender lips and have camber plates. i caught both fender lips with 205/55-16's. no idea about the rears. i have heard that 245's fit on 17" x 9" wheels - with a few mm to spare. that's not much room. you have to remember that when shocks / spring compress, the clearances get tighter
iMHO, you should have changed the lip / barrel on the wheels to make it a proper size for the e9. i could be wrong, but i don't think i am. i just hope you don't learn a very expensive lesson.

Hello I couldn't fined a barrel If I could fine 1 inch shorter barrel would be the best front is 7.5 inch and it is ok back is the problem that is 9.5 inch wide
