Looking for rim style advice

Hello, fellow Z4 fanatics. I recently purchased my Z4 and since my friend told me about this website, I've been on it almost every night before going to bed. A lot of good info here. You guys are pretty helpful.

I was wondering if I can get some advice on rims. I have a white 2008 Z4 3.0si red and black interior with the sport package. The current rims I am considering are the Miro Type 942, VMR VB3 Staggered or the VMR 710 Staggered. What I really like are the VMR 715 because of the chrome lip. Does anyone know if it comes in 18" staggered? Which set do you guys think would look better on my Z4?

I'll be getting a set in 18" since it looks like if I go with 19", I'll have to go with low profile tires or I may get some rubbing. As it is already, the ride is pretty bumpy so I don't want to make it bumpier than it already is. I plan on using the tires that came with my car. I believe they are a set of bridgestone run flat tires. The tires are brand new.

Thanks for the advice!

You will have lower profile tires with 19s, but thats only because they will have to match the total height of your stock set. I believe 26".

I recommend 18s, from VMR, but you will have big fender gap and it will look off either way if you don't lower the car

To tell you the truth, I haven't inspected the car closely enough yet to check out the gap. I've only had the car for a day. I have read people having success with Konig shocks and eibach springs. I'll have to look into this even more and see how much it effects the ride and handling. I don't have any speed bumps in my neighborhood so maybe lowering the car won't be a bad thing. One problem is that I may be voiding some of my extended warranty if I get anything done to the suspension. 19" and low profile tires may be the way to go.

How much harsher is the ride with 19" and low profiles tires?

19's will make your brakes look tiny, and your fender gap look huge, but...

the V715 is a lip-style wheel. lip-style wheels in 18's appear, optically, smaller than they really are. if you plan to go with the V715, please make it 19". i promise you'll regret it otherwise. you might consider a lemans style wheel instead though, as there are more spokes to hide the tiny brake effect.

also, don't forget to plan for an alignment after your install. adding an aggressive offset (a lower et number) will give you toe out (negative toe) in front. this is not so good. so make sure your bank account has enough in it to compensate for that.

typically, "bumpy" is not what i would call stock sports suspension. i'd say it's more "sharp". ditching the runflats will dramatically reduce the jarring sensation. it will also mean you'll need an ///m mobility kit, in case you have a flat.

also... welcome to zpost!

It really depends on what you style you're looking for. VMR wheels are solid but the V715 only come in 19 inch fitment. These days it's all about concavity anyhow .

Here's some quick pictures of VMR V710 and VB3 for your reference.
















Feel free to let me know if you'd like some pricing, we are an authorized VMR and MIRO dealer.

Ok, so what I gather is even with 19" wheels, I'll have a big fender gap even I don't use low profile tires. Either way, I really need to lower the car to get it to look flush. If I go with 18" with a lip, the rim will look smaller because of the lip so I should go with 19".

If I go with 19" and regular profile tires, what's the chance of it rubbing as I've seen other people complain has happened to them? Or did their's rub because their car was lowered too much?

Now going back to the alignment issue. Typically, how much are alignments at a BM dealership? Are alignments covered by the maintenance program I purchased?

Cal@SonicMS,
Those VMRs on the Montego Blue Z4M Roadster look pretty darn good. The car isn't dropped, is it? It doesn't look like it when compared to the white coupe. Those look really flush.

things rub because the fitment is too aggressive of the wheels, or the tires are too fat. Not because the tires are too tall, like I said before, your overall diameter MUST stay the same. Otherwise your speedometer won't work properly, odometer also.

The Montego Blue Z4M roadster is running on 18 inch VMR VB3 and I believe it's stock suspension.

OP - keep in mind the concavity on the rear of your z4 will be much less than what is pictured on that blue z4///m roady. do not expect yours to be that deep if you order wheels based on any rear wheel on an ///m you see. ///m's are significantly different in terms of what will and won't fit.

also, Roffle has it right. stay as close as possible to stock circumference on new tires as you can. the last thing you want is an incorrect speedo, ABS issues, DTC issues, etc...

i do not know of any case that an alignment would be covered under maintenence. you will need to pay for it.

Got it. Stay close to 26" Diameter or things will go awry with the instrumentation, roll-out, DTC, ABS, etc. To get it flushed, I'll need to drop it somehow. Either with lowering springs or shocks and springs.

If I get new 18" rims but keep the same tires or if I switch from the run flats, I need to keep the same size that I am currently running and everything should be good to go.

I just checked out the Adv.1 website and they've got some nice rims. But they are closer to $4500 a set. :-( If I spend that kind of money on rims, that's just less money on other things I may need to get. Will have to think about this one. Since I bought the maintenance program, I really can't mess around with suspension or the brakes.

Thanks for all the help, guys!

@Roffle Waffle,
Looks like you've got a set of 19" with low profile tires? It looks pretty sweet!

@Cal,
Thanks! The Montego Blue Z4 doesn't look bad with those rims. Something I will need to strongly consider.

@v3.0si,
I did call the guy who sold me the car and alignment will not be covered. :-(

FYI - maintenence programs do not cover suspension parts. those are only covered by warranty, or extended warranty.

Thanks! That's the dilemma I'm in now. The more I look at this site, the more I want to drop my car with coil overs. But doing so will void my extended warranty. Maybe I'll just go with 18" rim, new tires to replace the run flats and hopefully the ride won't be as harsh. I've got a few more months to decide.

it will only void the warranty on the factory parts that are no longer there, and any parts that they can proove were damaged by the aftermarket parts.

an obvious example...

just because you lowered your car doesn't mean they won't cover a leaking rear main seal.

Thanks for all the advice, guys! I've decided to go with the VMR VB3 18" staggered. Still not sure what tires to go with. No matter, in about a month, the car will just be sitting in the garage for the winter. I won't be getting the rims and tires until this spring.

Guys, isn't a 3.0si with Sport package already lowered relative to a 3.0si without Sport Package?

So, if one were to swap out the stock Style 108 rims with some VMR 18 CSL style rims in a staggered set up, with say the same size Hankook V12s that I currently have on my 108s, wouldn't it run properly without rubbing - and also look correct with respect to the gap between the fenders?

yes. the ///m-sport suspension is, if you believe BMW, 15mm lower than the non-sport suspension cars.

235/40 front and 265/35 rear will yield no rubbing.

you will still have fender gap, albeit 1/2" less than non-sport suspension. my car is a very similar look (fit-wise) to the VMR 18's... http://www.zpost.com/forums/showthread.php?t=515290
...and you can see how some angles make the car look tall, even with the ///m-sport susp.

thanks!

how about on a car without Sport package? Do you think the same set of CSL reps in 18 inch size and staggered would be okay? (I have two very good friends who have each just recently - and quite independent of each other - picked up really nice 3.0si's. )

Cheers!

Here's my car with the sport package:




I'm not sure if this is 15mm lower than without the sport package. The dealer wrote down that I should be using 225/40R18 F and 255/35 R18 B. After researching and much contemplation, 18" VB3 Staggered with some Hankook V12s is the way I'm going. I haven't decided yet where to buy them or if I'll buy them now or just wait until spring. Since I got the car last week, all I've been doing is scouring these forums and websites for ways to blow cash on it.

@Huz Z Let me know how your friends' cars turn out and post some pics!

sport... non-sport... the only difference is the height of coils. most people with the non-sport susp find they have a bit more clearance up front when using the 235/40 tread because it clears the liner just behind the reflector a bit easier. if someone were to use a "square shouldered" 235/40 on sport susp, there is a chance of rubbing... if you're concerned, use 225/40 instead. since VMR uses an 8.5" et40 on their VB3 instead of an et35 like they do on their damn-near-everything-else, there shouldn't be any issues. keep in mind you'll need an alignment anyway, as increasing to an aggressive offset will yield toe-out up front. if there are (there won't be) any clearance issues, the front camber can be corrected at that time.

OP - sorry for the sidetrack... but one must answer when the president () asks questions!

speaking of which... how did you get to be president? do you have a cabinet? what kind of duties do you perform? i don't know what district i'm in, where do i go to vote? where do you stand on canada's southern border, and its current needs for a very tall fence to keep out all of us roudy american?

(all rhetorical of course... i just like that we have a president!)

those 108's are definitely sport pkg wheels, but i'm still confused by your seats...??? in any case, the car sits like mine does (i.e. no GIANT fender gap).

225 & 255 are the stock sizes, but you'll find that they'll look very stretched on 8.5" & 9.5" wheels respectively (especially so for the 255's). consider talking with your wheel rep about tire sizes before you install them on your car. i personally would go with 235/40 & 265/35, but in the end it's your car and you should do what you like.

I'll definitely finalize wheel size first before making the order. Thanks for the heads up! Are those the wheel sizes you have on your car?

Glad to know I'm going to need an alignment after getting the wheels put on. I'll make sure to bring them to the dealer to have the wheels put on and an alignment. Is there a suggested alignment for these kinds of rims for everyday aggressive driving and maybe some autocross next year?

As far as the seats go, I'll take pictures of the interior as soon as I get my pedals and armrest in and I'll update the pics in my garage so you get a better idea of the seats I have.
