AZA Z1's 18X9.5 rear 40 Offset... ????

[ELESTWO]

I just got off the phone with Wheelmax, and I have a deal on the table for a set of Z-1's staggered, but the rears they have are a 40 offset rather than 45. Any trouble there?? Im thinking of grinding the rear wells. The tires going on the back are 265/35/ZR18's. Should get a little wider stance. Anyone out there have this setup?? Its an awesome deal, thats why Im considering it. Any help would be appreciated! Thanks!! :stickpoke

You need at least a 45mm offset!

[ELESTWO]

Well, the guy there doesnt know what he's talking about then. He told me a 40 offset would work if the wells were ground. Its only about a quarter inch were talking about.

You have to cut or roll with a 45mm offset is you have stock springs or lowered!

[ELESTWO]

Okay, how about this??? What if I put 8.5's all the way around with a 40 offset?? Then I should be able to grind the wells and be ok?? Also, will be able to rotate. FYI... I have the back end lifted a bit with adjusters in the springs. I can make it so that the well doesnt come down far enough to hit the tire....... just a thought....

That might be too much tire for a 8.5" rim. Maybe someone else here would know.

[DAFFYDRUNK]

18x9.5 40 offset? I'd stay away unless you're willing to do alot of work to stop the rubbing. Not even sure it's possible without major surgery.

add: Might be able to do 255s on all fours with 8.5" 40 offset rims. Even then you could have probs rubbing the front strut and rear fenders. Probably stay away from 265 with those wheels. Depends on the tire I suppose...

[ELESTWO]

No, if I was to go with the 8.5's, I would be putting 235's on them, not 265's. Maybe 245's at the largest.

[1evilgoat]

You can put 245/40's on the 8.5 with no rubbing
I had a set on falken wheels with a 38 offset
Now i have Z-1's staggered they look much better

[ELESTWO]

Yeah, I originally called about the staggered, but the 45 offset wasnt available. All they had was the 9.5's with a 40 offset.... From what people are telling me, it will stick out a bit too much.... It looks like I will have to go with the 8.5's all the way around with 245/40's. I think that will still look pretty good!!!

[Gregory]

I also talked to a gentleman at Wheelmax about some 8.5 and 9.5 on 19" and he said he would work with me as there are different offsets. I'm planning to roll my wheel well lips, but I'm confident it will work with 275 series tires and an offset of about 40mm.

[ELESTWO]

Well, my original plan was 18X9.5 on the rear with a 40mm offset, but the response Im getting is that it will rub bad!! According to wheelmax, it would work..... dont know what to do at this point. I have spring adjusters on the back to stiffen or even raise it up a bit to keep the rears from rubbing.....

[msnell]

18x8.5 40mm offset with 245 all around will work fine w/o fender mods, thats what I'm running on stock suspension.

[mrtosh]

Alan, you've seen my car in person, so take comfort in knowing that I'm running 19x9.5 w/a 40mm offset and 275/30/19's(the 18x9.5 w/275/35/18 is the same height as the 19's setup). I do have the fenders rolled and have drag bags. I've run no air in the bags and have had no rubbing(even w/"spirited" driving). I only have the bags at about 7lbs. right now only for looks. Also depends on the tire you run with. Some brands have fatter and taller sidewalls than others. I have the General's, the Toyo's should be fine too. There are plenty of guys on here running the same width and offset w/no problems. 5mm is just over 3/16". If it does rub bad enough, there's a guy in Hopkin's who will grind 5 mm off for like 40 bucks a rim...

[StinkFingers]

Tell you what AL, you buy that same "wheels" as me and I will here after refuse to drive anywhere near your car. You will be flying solo along with your JBA shortie headers.

So, I should be okay with the 18x9.5s with the 40mm offset. I like the stance you have with the 40mm offset in the rear. Ill just be on 18's instead of 19's. AWESOME! Thats what Im gonna do then!! And Dave, youre funny!! You dont want to ride anywhere near my car if I have the same wheels, but you want me to get the same headers!!! Damn dude, make up your mind!!

Do what you want..... but 18x9.5 w/ 275 tires do rub on a 45 offset even with fenders rolled on occasion. When the Z-1's first came out they only offered them with a 40 offset and few members here bought them. Each member had to seriously grind off the lip. I recall seeing pictures and the lip was completely gone. One had a problem down the road with the fender deforming becausing he took off 100% of the fender lip. Additionally, most ran drag bags as well. I'm sure, due to variations between cars, some people have made 18's with a 40 offset work..... but it's typically, not always, but typically a major ordeal. As well..... it has been proven several times that AZA has some inconsistancies with wheel offset. As example, mine are supposedly 45's on the back.... but they are actually 43's. I have more problems with rub then most that have supposed 45 offsets. When it comes to Wheelmax you want to make sure you get the right thing the first time to reduce the risk of having to deal with an exchange with that company. If they tell you they sent 40's, but they actually spec out at 38 or 39, they "might" tell you to go pound sand.

I would not personally risk ordering 18x9.5 40's..... you would be better off going with a 19 x 9.5 if they had 45 offsets.

There is also the look to consider.... I personally do not like the look of wheel that sticks out too far. The difference between too far and just right however is just a matter of mm's. If my 45's had been 40's I believe I wouldn't like the appearance because they already stick out pretty far when viewed from the lower portion of the fender opening... and they are just shy of flush on the top portion of the wheel opening.

I actually have some 18x9.5 with a 45 offset that I would consider selling..... but they have the infamous clear coat problem and they might not match colorwise.....so it's probably not a good idea..... but in all seriousness I would stay away from 9.5's in the back unless it's a 45 offset.

[StinkFingers]

No funny is where I have your wheels shipped back when they arrive at "my" house. Or even better drive them over and put them on your front door for your "ball and chain" to see along with the receipt, then she can ship them back. Either way your fudged so you are better off just looking elsewhere.

There is no denying it, pacesetter is a good header for the money, Shorties are not. Do it once do it right. Asshat. :wall:

[mrtosh]

LOL... Shit's getting deep in here. Honestly the 40mm offset doesn't stick out at all. If you were to stand over the fender and look straight down, you'd see no tire sticking out. Read post #49 for some more "inciteful" info...

Post # 49????

Looking straight down from the top of the fender maybe you are right, but from the rear they do look pushed way out. Mine are mm from being flush with 275 Hankooks and a 45 offset when viewing from the top..... my lip is folded almost flat and I still get rub without dragbags being inflated.....

[Gregory]

Let's see now, you're post #19, where is the #49 you reference.
Or, is that coming up next week?
:huh:

Shit Sean used to run a +35mm offset in the rear w/a 9.5" rim and he only had fenders rolled...

[bill12s]

Good post MrTosh

-- 18/19x9.5" -- 40/45/+ Rear Only, Fender rolling required, recommended tire size: 275/35/18 or 275/30/19 (can't go to 275/35/19 without serious modification--rolling diameter too big) You can do a 285 in the rear with the same profiles...we've done it before and going with a 45+ offset is the better choice but it could be pulled off with a 40. I wouldn't package it that way for general sale though.

Now realize that when you put a 285 tire on a wheel with 45et, you are in effect, making the fitment on the fender side, equivalent to a 275 tire on a 40et wheel! You have to remember how the width effects offset--same goes for wheel widths and that is why a 38et works on 8" and 9" wheels.

A lot of people seem to get hung up on the numbers and as soon as they see it, they react like its the plague. Just keep in mind that the difference you are talking about when going from a 40 to a 45 is ONLY 5mm!!! That's LESS than 1/5 of an inch! 5 hairs or 5 fingernails thick...we're not talking much. Hell, I used to run 35et 9.5" wheels on the back of my goat; only thing I did was roll the fenders completely.

I think the funniest thing is when people say "they stick out too much", really, you can see a 5mm difference in a picture taken from a distance??? Sorry, I don't think so. Now post the same picture and tell everyone it is a 45mm offset and no one would say a thing. Don't let your mind trick you.

However, what snafu doesn't tell you is that his car was almost undriveable with the 35's... he couldn't give it any gas and he couldn't hit a bump. Then when it comes to 40's he was extremely insistant to me not to buy the 40's..... he's the same guy that convinced me to wait on my purchase until the 45's came back in because of looks and fitment.... so his info to me and what he typed in that post contradict.

I guess the question is simple... MrTosh are you trying to say that without dragbags limiting your suspension travel are you willing to say that AZA Z-1's with a 40 offset and a 275 tire will not rub your fender assuming its rolled in a traditional manner. (as in with a Eastwood Fender Roller)?

I'd be surprised if you say "it won't rub".... because it will unless you go overboard on the fender grind/roll..... The main thing people use to prevent the rub is drag bags.... which I'm not questioning.... other than to say you are limiting suspension travel and as long as you know that.... then the OP should order the wheels.... I just think he needs to actually understand what he's getting.

Yes, he says that in his "advertising" post.... but that's not a 100% true statement. The OP should call and talk with Snafu about fitment on the telephone.

Depending on the brand of tire, yes... Like I've previously stated I've run w/no air in the bags and have had no problems. Unless I'm one in a million. I've even had about 400lbs of passengers in the back w/the bags at only 7lbs w/some "spirited" driving and have had no issues. I've had the alignment in the rear checked as well as the camber, both are nuts on. Now granted I "may" have my fenders rolled more than the average person(although I'm not sure, seeing as how I've never seen any other rolled fenders in person). There's still around 1/2" of lip. Every car is different. Depending on the cradle alignment and the rear camber of that particular car, who knows. Here's a pic of my rolled fenders...

I'm not here to start another opinion war... I did also post above that if he was having problems w/the 40mm that he can have 5mm shaved off. Like I said every car is different. However, after talking to the OP tonight, he now has some 19x9.5 w/a 45mm offset in the rear w/no fender cutting and some adjustable springs and has no problems.

Likewise, I don't want to start a pissing match either. I can only post from my experiences and you for yours. It is crazy how much the tolerances on these cars vary. If he has 9.5's with a 45 offset now, without rolled fenders then obviously a 40 offset and a slight roll will not be a problem at all. But I've got to believe he either has those springs super tight or he has a freak car with wider fenders then the rest of us.

Realistcally, you provided a good solution to the problem by having the offset increased by your source if there is a rub problem. In fact, as seen on the custom wheelsets you could run a 10 or 10.5 inch rim with a better offset. Something in the neighborhood of 50 or 55 offset you could fit a 10.5 with barely rolling the fenders.

Additionally, looking at your roll job, I'd have to say either your wheels aren't a 40 offset or my wheels aren't a 45 offset. My fenders are rolled much tighter then yours and I get rub...... however it's only with something in the trunk or kids in the backseat... and only when you hit those long compression dips. Doesn't really rub on the quick hits because of the shock dampening, but rather it's a problem on the sweeping dips like at the bottom of a hill.... when the dip causes the suspension to slowly dip... (the shock doesn't dampen enough)

Could also be that the dampening between my 04 and the 05/06's is a bit different.

Ultimately it can't hurt if the offset can be changed for the price you listed. If I was in the OP... I'd buy the wheels if fitment could be altered that easily....... Well, maybe not, but not because of wheel specs... but more because of my dislike for wheelmax.

[ELESTWO]

Okay...Im the "OP" here.... Ive "temporarily" got the 19"x9.5/45mm offset on there right now. Another "OP" wants his wheels back.... changing of minds....again... So, I adjusted the order that he originally wanted and went with the 18"x9.5/ 40mm offset with 275/35/18s. My wells are not ground or rolled.... Ive installed some spring adjusters that can stiffen the spring travel and not allow it to rub.... Maybe a little if I hit a LARGE bump or something. Like Ive said in the past, Im not looking for "mind boggling" performance. I just want it to look good. I like mrtosh's look. It doesnt stick out too far.... As a matter of fact, just standing next to it you cant tell if its a 40 or 45 offset. With this "OP"s wheels on my car... for now... I have adjusted the springs so it doesnt rub. Im guessing the overall height of the 275/30/19's will be pretty close to the 275/35 18's I will be installing next week. So, with all this "war of words" going on, I will try to put it to rest when I post the results of how it comes out, along with pics.

[Rolencode GTO]

Well I guess I'll chime in here as well.

I have 19x9.5 40mm(shaved to 43mm) on the rear of my goat. I have koni rear adjustable shocks. I have very little rubbing, veeery little. My fenders are also cut and rolled.
