19" tire help (spacers?)

Just ordered my 09' m3 coupe and looking at rims/tires. Im ordering the H&R sport springs and trying to guess by reading as much as I can on what size to go with on the rims/tires.
I am getting the Vorstein front and rear CF lip/diffuser also so was thinking of going with the :

19"x9.0 245/35 front
19"x10.0 265/35 rear

I think I wanna stay with 19" rims
and would rather not use spacers but I would like suggestions on rim and tires sizes I should use..and spacers if you feel its needed.
Any help on tires/spacers with 19"s would be helpful.\\-thanks

You need to post the wheels offsets to properly determine if spacers are needed/can be installed at all.

Im a noob but i guess the rims would be off-set specific for the M3 size? when I look to order rims they ask for make and model to ensure fit.?!!>? So... I put in... say... 19"x9 on the order.. do i need to request a certain off-set? If so what do you recommend? for front and rear at the sizes I mentioned at top.

The "flush look" is a personal thing, some members prefer the "barely-sticking out" look, others like me like the "barely inside the fender" look.

A front 19" x 9" wheel with an offset of 20 will look like the OEM 19" front wheel with a 15mm spacer. A rear 19" x 10" wheel with an offset of 15 will look like the OEM 19" rear wheel with a 13mm spacer.

So a front ET20 and a rear ET15 with those custom wheels of yours should fill the fenders up to their very edges without rubbing with those tire sizes.

can someone explain the "ET" thing I want the Flush look I guess. Also would it be better you think to go with 19"x9 245/30 front, 19"x10 265/30 rear instead of the 35?

That's the offset term, dude... when you talk to the vendor of your wheels they will know what you are talking about if you tell them those ET numbers. If they are a very experienced vendor they can even recommend other offsets for you depending of what you tell them that you want...

Good luck.

How about I make it easy for you. Go with BBS LMs in this fitment for a "custom made" look. They will be perfect for the car and not require spacers

19x10F ET25
19x11R ET25

Done.

Hey Newb! Read this: https://www.rsracing.com/tech-wheel.html

Specifically, "Measuring wheel Offset" and "Wheel Terminology" sections. Once you've read and understood those sections, you'll be good to go on the concept.

Once you've read that, read this:

Ideally, you'd just buy the offset you want, as you said.

If the wheel you want has too high of an offset, the difference between the actual offset and the offset you want will tell you what size spacer to get.

So if you want a 20 offset (ET20 for short) and the wheel is ET35, you need a spacer that is 35-20 = 15mm. If the wheel offset is too low, ET10 for example, theres nothing to do except get a widebody kit.

Thank you for the link on sizing the rims.
Im at work and manage to skim through it. But, for the most part the rims Im considering are suppose to be completely custom ordered to fit my needs.... I was assuming that I would be able to custom order the off-set of the rims also. Im waiting for a reply about the specs I gave to them: 19x9 ET20(front), 19x10 ET15(rear). I was thinking of using 255/35 (f), 275/35 (r). I was wondering if I actually can order the rims to spec above how well do you think it will fit with the tires I listed on it also lowered using just H&R sport spring.
