Any problems with these specs? Need spaces if lowered and will it poke out? TIA

Original question: Has anyone mounted Style 326 (19" from E89 Z4) on an E86 (e.g. 2006 Z4M Coupe)?
Answer: Yes - http://www.zpost.com/forums/showthread.php?t=644663

BMW E89 Z4 Genuine M Double Spoke Style 326 Wheel Set
Front Wheels - 8JX19 ET:29
Rear Wheels - 9JX19 ET:40


http://www.1010tires.com/Tools/Wheel-Offset-Calculator shows the fronts would stick out an extra 13mm (~0.5inch) and the rears would be in about 10mm. I assume a 10mm spacer would fix the rears and the half-inch in the front would be negligible/based on tire choice.

I have stock suspension, but kicked the front camber in via the camber pin removal trick.

Anything I should be concerned about, clearance-wise?

Help - need offset advice!

TIA everyone.

I understand the OE wheels and tires are the following sizes:

F 18 x 8 ET42
225/45/18

R 18 x 9 ET30
255/40/18

So this is what's confusing me.

1) I'm currently running 10mm spacers with the OE wheels and tires. The look is perfect...I DO NOT want to extend the outer surface (street side) of the tire any more to the outside no matter what width of tire I use. I want to keep using the 10mm spacers so I can mount the OE 18's for longer trips

2) I know a number of you run a 245/275 combo with no issues but I want to use a 235/40/19 and 265/35/19 setup in Michelin PSS. (So, slightly taller than OE which actually is what I want, and slightly wider).

3) I'll be ordering wheels in 19x8.5" and 19x9.5" but the company wants me to specify the desired offset.

4) Assuming that the extra 10mm tire width and 12mm wheel width would be all to the inside, what should I specify as the offset? Am I correct in taking 10/2 adding it to 12/2 = 11 and therefore adding 10 or 11mm to the OE ET's of 42 and 30 to get the look I want?

On there way!!

VMR VB3 19" Silver

2 Front - 19x8.5 ET40 245x40 - 19"

2 Rear 19x10 ET25 275x35 - 19"

4 Hancook Ventus V12

Ordered from our good friends at EAS - lets see how I make out at customs and duty and taxes The tires and wheels are probably several hundred less cost than here and I have only seen one Imola Red with the CSL replicas in the silver so if they get here before the snow, I will post some pics.

Hi guys, i tried reading back to see if this has been asked before but didn't notice it and to be honest i got lost in all the various numbers and figures..

My question is this, which wheel spec should i choose in order to have identical wheels and tires all around? I'm thinking 18x9 all around with minimum of 255 wide semi-slick tires (think R888 or similar) But i've no clue about offsets!

I don't mind using spacers if needed anywhere and as they'd be my track wheels i don't care if they look flush or not. I also don't care if the tires are a lower profile than stock.

I figure having 4 of the same wheel/tires is easier to swap axles and/or sides so they'd last longer.

At the moment i'm on stock suspension although with the pins pulled out so around -1.5 camber up front but eventually i'll go with a suspension kit and camber plates so more negative camber will be added if/when required.

If my reasoning is not sound or if it's even not physically possible please say so! I'm NOT claiming to be an expert here.

Give it a shot

IF you want to use 18x9 wheels do you want the same offset or space between the fender and wheel as on your stock wheels?

If you do that you can have the 18x9 ET 30 on the rear and 18x9 ET 40 on the front and all you do is add about 1/2 an inch on the inside and outside in the front so their should be lots of clearance, You probably can move them out a little more if you wish but depending on where you get your wheels they can help you.

In terms of Tires 255 or 265x35 - 18" tires

You can put any tires you want and the calculation for wheels is related to the width of the wheel. Where they fit in relation to the struts and the fenders is the offset and there are MANY MANY combinations depending on the make of wheel

Thank you for your reply drbvac. Is there not an option for using the exact same wheel all around? Instead of different offsets front and back? Say for example 18x9 30 offset on all corners?

18x9 et 30 will be very aggressive for track use without some added camber. Also, remember you have a bbk, so not all wheels will clear. I would strongly recommend apex wheels for track use. 18x9.5 et 35 seems to be a common square setup with aggressive camber

I recommend 9.5 +35 square on 255/35/18. Rear will need atleast a 10mm spacer to make it flush. I recommend running -2 up front for clearance. A 5mm spacer may also be needed to clear front strut body (some say it clears without it, but its a little too close of a clearance for me).

Here are some pics for reference to my setup.

Apex are expensive to ship over here though. Was thinking about Team Dynamics Pro Race 1.2. Can get them in many offsets (including the aforementioned 18x9 30) are light, pretty cheap and people report are BBK friendly. I think 9.5 would be overkill for the front for me.

i2ichal2dZ4M, i don't mind if they'll sit flush or not seeing as they're only going to be used on track. I first mentioned the 18x9 30 offset because that's what the rear OEM wheel is and was the first thing that came to my mind. Eventually more negative camber will be added to the car of course. The wheels are mentioned are available is many offsets so i could probably get them in something else if it would fit better.

9 +30 would work if you are set on that setup. Ideally, with my 5mm spacer im technically running 9.5 +30.

Fitment will depend on the particular strut used though right? And I've no idea which kit it will be yet... Anyway you've both been helpful dudes.

Yes, mostly clearance issues were related to KW setups because the spring perch height is relocated.

Got me confused now boys - Do you not have 9" with ET 25 with your spacer? The spacer reduces the offset - doesn't change the width of the wheel ?

so the new ze40's from volk looks perfect to me;

here are the specs for bmw only;

18x8.5 et 50 face 1
18x8.5 et 30 face 1

18x9.5 et 50 face 2
18x9.5 et 40 face 2
18x9.5 et 20 face 3

18x10.5 et 20 face 3

my question is would 18 x 9.5 et 40 be too aggressive for the fronts? and then the 10.5 et 20 rear?

on stock suspension.

Added 10mm spacers in front

VMR VB3 19" Silver
2 Front - 19x8.5 ET40 245x40 - 19"

Member suggested I do this to get the same appearance from the fenders

Bumped them out 10mm and they look better I think but does anyone have any idea if it changes the feel of the tires on the road or the alignment? Nervous to put them on - not hard to get off

Will the following fit with no rubbing on stock suspension, no fender rolling, etc. Will be used for autocross.

FRONT: 265/40/18 on 18x9 ET31
REAR: 275/35/18 on 18x10 ET25

I'm hoping for a quick answer as I am trying to get in on the APEX group buy... thanks in advance!

Edit: 265 - wishful thinking!
