Need Help .. 98 Q45 with 2006 M45 wheel? i have a 1998 Q45 and i wanna put a 19inch factory /M45 wheel on it ... i know the bolt pattern is the same but what kinda spacer do i need 15mm 20 mm or 25 mm . ... ?? has anyone done this or know what combonation work for this , also i dont think i will need hub rings ? ... i tried to put the front wheel on and it hits the strut ... any help is greatly appreciated .. eddie 917-559-6059 or [email protected]

18x9 with a 35mm offset barely clear the struts by 2mm-3mm. You want the offset in front to be at least 32mm-30mm. 25mm is pushing it, especialy if lowered. Any less, and the tire will hit the fender.

Car is at factory height, I want it to look right and not rub. What size should I go with? and who carries them?

19" wheels won't look right at factory height.

what lowering kit you have on your car? how dose the car ride ? still smooth ? send me an e-mail will get you over a pic , you tell me how it looks !! [email protected]

[97Q45t]

You got mail! BTW, the email address in your profile is missing an "i".

My car has 2" drop Tein springs. The ride, of course is worse than stock, but still liveable. The 2" drop Tein is a little softer than the 1" drop Eibach. Contact Kevin (user name: FalkDesigns) for the Tein springs.

19" wheel from the 2006 M45 is 19x8.5 ET50. 25mm or 30mm spacer would be fine.

If you really want to do this, then you have no choice but to use a spacer (although I personally consider this to be a poor decision - some people here think they are fine ... I would not do it).

With a 8.5" wide wheel, remember that that the tire section profile is also important for a Q45. Particularly with a 19" wheel, since you don't much tire aspect to allow the section profile to not be an issue!

These means that you have to be a lot more precise with the offset than with a 17" or 18" wheel.

I suggest that deviating from 32 to 33mm offset (worst case 35mm) will cause one of two problems: strut contact or fender rub. This means that you need a spacer of 18mm or so ... I'd try 15 or 20mm to see how they work out.

Here are earlier posts of mine on this topic! in M45 forum and in Q45 forum

Hmmm ... I think that would be too much of a spacer. Would make the "final" offset be 20 to 25mm, and that would make it stick out under the fender quite a bit. A "final" offset of 32mm would be better.

so your saying to use a 35 mm spacer all around ? 15mm? (245 in fornt and 275 in the rear ) i need to order these spacers up ... thanks eddie

Syed,The Y33 Q is a little wider than the Y34 M45. Therefore, the Y33 Q will be able to accept the same width wheel with less offset (about 10 - 15mm less). I tested fit the 18x9.5 ET22 with 275/40/18 on my friend's Y34 M45 and it stuck out about 15-20mm off the fender. Same wheel and tire were mounted on my Y33 Q and they were perfectly flushed with the fender.

Compare the 18x9.5 ET22 with 19x8.5 ET50, the difference in offset is: 0.5 inch + 28mm = 40mm. So a 25-30mm spacer to compensate for the difference is modest, I'd say.

Eddie,So are you planning on dropping your car or not?If you are going to drop your car, this is how the wheels will fit given that a 32mm spacer is used with the '06 M45 wheels:

There's still about 10-15mm clearance on the rear fenders, probably a bit more than that up front.

Bottom line is:If your car is dropped: 30-35mm spacerIf you car won't be dropped: 25mm spacer

35mm offset in front will probably put your inner rim very close to the strut.

I have 18x9 35mm on mine with 255/40-18. Only about 3mm clearance to strut.

I would recommend at most 32mm, 30mm would be better.

Ah, yes! I was thinking in terms of the first-gen Q45. Sorry if my comments are not applicable to the 1998!

If they can handle 6000hp at 335 mph, I'm fairly confident they can withstand anything a Q45 could dish out. Provided of course, you get good spacers. The ones I ran, that Q_ship bought from me, are made by someone who's main customers are drag racers, so I have no concern about safety with them. Whatsoever.

For Y33 Q45, the perfect offsets from my experience and learning, would be +10 mm in front, and +20mm in the back. My wheels are +20mm all around, the rears are perfect, but the fronts are still tucked in ever so slightly, so I'm getting 10mm spacers for the front.

Also, if you want to drop it, I will have 3 extra sets of Tein S-techs in about 2 months, I recently ordered 5 sets, 2 of which are sold, 1 is pending, and that leaves 2 sets available. I hate that we don't have a PM feature on this forum, (these "Hey so-and-so" threads are the ultimate in ghey), in any case, email [email protected] if you want to reserve a set.

[97Q45t]

Also to add to Kevin's post, offset number alone is a meaningless number unless it is accompanied by the width of the wheel. Kevin's car has 19x8 and 19x9.5.

8" width with 10mm offset, look perfect like Kevin said, is like an 8.5" width with 16mm offset. M45 wheels is 50mm offset, so 50 - 16 = 34mm front spacer.

9.5" width with 20mm offset, look perfect like Kevin said, is like an 8.5" width with 8mm offset. 50 - 8 = 42mm rear spacer (calculation wise). Since 275 width tire will be wider than the 8.5" width wheel we should use 35mm (or a little less) rear spacer.

These numbers are consistant with my susgestion of 30 - 35mm spacers if the car is dropped.

Are you running 245/40/19..? If you is the tire touching the control arm from the back of the tire or is the top of the tire (near the tread) touching..?

I doubt you need spacers what you need is a smaller tire. Forty is to thick.

Run 245/35/19 and you will not have the problem. I know because I am running 275/40/20 in the back and 255/35/20 in the front.

I tried 255/40/20 and it was two big. Run 35's and you will be fine. You got to understand that is a pretty big rim. So you can not run the 40 width that is a thick tire.

[szh]

For completeness, note that the 1998 Q45 manual shows the stock wheel as 16.0" x 7.0" with a 40mm offset (this probably still leaves a fair amount of space to the struts, I suspect.)

A 9.0" wheel has 51 extra mm (compared to the stock wheel) that must be "absorbed" somewhere - that must be added to the extra 10mm offset that the new M45 Sport wheel has. Of course, only half that 51mm amount must be compensated for to avoid contact with the struts, since the wheel is half that total extra width around the hub contact point.

So ... to make a long story short, it sounds like a spacer of 25 + 10 = 35mm is needed for the same space to the struts as the stock wheel. Since the original wheel was probably not too close to the strut, and you don't want the wheel too far under the fender, a spacer about 30mm would probably be the right amount, I think.

Regardless, I stand corrected ... my previous comments were wrong (correct for a first-gen, but wrong for the 1998 Q45)!

Q45Caliber, he needs spacers regardless if he goes with 245/35 or not to make that high offset wheel work right, that offset will be completely sunken in, with like 2" to the fender, kinda like a Ford Explorer "Sport" lololololol.

[BadQ45t]

Okay, I have a set of 19" M45 sport rims in the garage. I took them to my mechanic in LA to determine fitment. The rears are just fine and the fronts will fit with spacers no sweat. he's 100% confident that you can do this no problem. I'm back off this due to money constraints to buy the tires and the fact that I'm going to sink a bunch of money into shocks and springs right now. I will sell them to you CHEAP, I stole them from someone (not literally).

Kevin can setup a spacer guy for you, you will FOR SURE require them on the fronts, optional on the rears but it would look silly.

E-mail me at [email protected] and you will not believe how cheap I picked these up for...It's killing me selling them but I have to get shocks and springs before I do new rims.

[szh]

As you perhaps also noted, 19" tires are darn expensive!

the wheels are on and they look great !! the spacers worked out great to ... they are perfectly contoured to the body like yours are in the picture.. Thanks all you guy for your help , i will get a pic out there soon ...

[BadQ45t]

really, interesting. i have a few questions. First how big were the spacers? Where did you get them? Where you able to use the same lug nuts? Where you studs long enough or did you need to make longer ones?

Just asking, I think I have mine sold but at the end of the day if nobody grabs them in 10k more I will have to just mount them now that I hear of a success story.

[[email protected]]

well just like 97Q45t said , i used a 1 inch spacer adapter .. E-mail me

[maxnix]

Picture post please. What tire did you fit with the OEM minimum 95 load rating in the OEM specified 26" diameter?

[BadQ45t]

Infinitied, you've got mail as you at AOL say. Please do post pictures, now my curiosity is raised just enough that I might just keep those rims if someone doesn't jump on them ASAP.

... Very Interesting Read on the above ...

* How does this discussion fit when using a staggered set of G35 RAYS Engineering 19" wheels on a stock Q45t with little to no mods?

* May be of interest:- I already own the wheels- The fronts have a 30 offset on 19x8- The rears have a 33 offset on 19x8.5

* I am thinking that 225/35 may be the correct setup. Any constructive ideas would be appreciated?

[BadQ45t]

I think 225 is going to be too small, these should work too but i think you might need some work with spacers. The best thing to do is if you have a mechanic that you trust drive your car down with one rim and have them check it out. Sounds like spacers will be required for sure and I know you're going to want more meat than 225.

[RAQ45t]

Not really familiar with the Q45 tire and wheel combo,but would like to learn. Previously,managed successfully to lower an E34 BMW 5 series by partially using Eibachs,but used a 225/50/16(16x8" rim) tire instead of the 225/60/15 tire that came with the car.IF you use a very good rated tire("Z") or better as I did, the extra lowering aspect,AND the safety and handling work well.That car(my 20th BMW ,and 7th track car) was dead steady at 140mph with the cruise control on;didn't even change lanes.The car also ran well on track road courses,as I was a BMWCCA instructor.

What year Q? As there's a significant difference in fitment between the G50, Y33 & F50.
