if arizona say it works with a +33.. then its probably as close as you want to get.. he runs some retardedly close stuff... so with a +38...........

If you are going to run THAT close.. You'd also better get some toe eliminator bushings.. if the tire is just clearing the swingarm, and you still have the rear steer enabled, you are going to rub the swingarm if you hit a corner hard enough to kick the rear steer in.

 

Well, I run a "retardedly" amount of hp so I need tires THAT wide

The rear wheels are +38 and I run 5mm spacer. With this spacer its close (but have seen worse) and I didn't even try it without. The thing I don't like is the tires are blocky and they seem taller (if you will) than my Pz-'s, but looks really aggresive... I'm good friends with Kevin Wyum and he runs 315's on and FD with no body mods... Now, lets talk close!


anyway, carry on

 

I don't doubt it works dude.... but you and I just look at it differen't..

My Kuhmo mx 245's still can't handle all the power my cars puttin down... BUT, the drag slicks will!!!!!! Thats the only time, personally, i need that much grip.. i RARELY hit the high boost button on the Profec B on the street... (although... 10 psi can still get a bit nutty in first and second).

However... if i ever damage the fenders, or If I go insane this winter... I'm going to slap a widebody kit on the car.. and then go nuts with the wheels!!!

 

Its all good, I was just mess'n with ya.

245's don't last very long for me, so I bought 275's.. They are to tall but the added traction is great. I was hoping my fitments would also help those on the fence... I would say my setup is max fitment depending on tyre manufacture... The Kumho's and RT-615's that I just installed are as blocky as they come... I'll try the rear with no spacer making it +38mm... I have my doubts.

 

front-7.5 wide, 45 offset, 225/45 or 50 (for tires i will be getting sometime), around a 20 mm adapter?

back-8.5 wide, 50 offset, 245/45 or 50 (same again), around 25 adapter?

i want this to be inside the wheel well too. one thing i cant stand, tires sticking like an inch out with beefy tires. i want to look like the perfect fit (haha). about how much clearance should those adapters be giving me from the springs? and from the inside of the fender? oh....and how much of a difference do you guys notice with wide adapters like this for steering?

and when measuring the wheels width, it goes from lip to lip right? the wheels are those sizes because its stamped on them, but i actually measured 8.5 and 9.5 i think. beats me....heres the link for my wheels if anyone wants to see them. https://www.rx7club.com/showthread.p...8&page=1&pp=15

 

Dude... I'm not even going to comment on the adapters, we've hashed that to death on this thread... pick another wheel.

If someone else wants to give you specs.. so be it.. I've grudgingly decided that up to a 5mm spacer is OK.. (and here in PA its about the limit to pass inspection).. but when you start having to put a block of metal 20-35 mm thick between your wheels and the hubs.. usually having to bolt the adapter to the hub and the wheel to the adapter.. thats getting retarded.

I guy at the local track had adapters on his car to fit third gen rims on in and when he launched.. it riped the adapter apart... there were pics posted in another thread a while back...

 

after putting on my 17x8 fn01rc's w a 25mm offset, the rears just arent wide enough for me. Im thinking of getting the 17x9 w a 25mm offset w/235-245's or should i go with the 35mm in the back (my fenders are rolled). Its probably been asnwered but id have to dig through 39 pages :p. Thanks -alex

 

why would it matter? im not doing this to make the wheels stick out 5 inches trying to be cool. im trying to make it actually fit right because the offsets so high. and ripping the adapters apart.............? send me a link.
oh let me guess.........democrat?

 

it happens, on the other message board 87GTR broke 1. Well I think it was him, you could do a search over there.

 

Allright... you asked for it...

YOU ARE TRYING TO FORCE A WHEEL THAT WAS NOT DESIGED TO FIT THE CAR ONTO THE CAR BY ADDING A HUGE HUNK OF METAL BETWEEN THE WHEEL AND THE HUB...

THIS IS NOT SAFE.

By doing so, You are adding X amount of length to the end of the lever arm of the suspension (the point wher ethe wheel meets the hub) , thereby increasing the amount of force exerted on the suspension components by the wheel. The rate of force added to the suspension is NOT linear, its exponential. This is basic physics.. leverage increase with distance away from the fulcrum point.

PLUS.. When you get into the realm of ADAPTERS.. you are adding a entire new set of lugs onto the car, thus adding another mechanical breakdown point. Not only do you have to worry about the lugs mounted to the wheel hub, now you also have a set that are outboard of THAT...

Is any of this getting through your head YET???????

BULLSHIT....... you obviously found a set of wheels that you think LOOK COOL... BUT THEY WONT FIT.. Therefore you are trying to find a piece of technical tomfoolery that will allow you to run those wheels on your car anyway. You've let you're vanity/lust cloud your common sense.

NEVER did i mention ANYTHING about you trying to look cool, having the wheels stick out from the fenders, being a ricer, or being a dumb ***... I just figured you were new at this so I'd give you another perspective to look at and then YOU go and attack my politcal views..

Truth be known, i do not subscribe to ANY political party... there are just as many *******, money grubbing, powermad, elitist bastards in the democratic party as there are in the republican party. Politicians make me want to fart. I try to do my best to vote for the lesser of two evils because noboy worth a **** ever makes it past the primaries. There hasn't been a presidential canditate i've WANTED to vote for since i've been able to vote.. and thats probably longer than you've been alive.. John McCain was the first one i even respected.. and he got assholed by big oil money from our fearless leader "Dubya"

 

Hey YearsOfDecay, I think something took a crap in YOUR poi today?


-Ted

 

Yeah..... one of those days.... BUT... I'm not going to apologize either... its a matter of perspective..

You and I both could tell that guy what size adapters he would need to run to make those wheels fit.. however, I'm not going to do it because I don't feel that its "safe". I don't care how many people give testimonial that they have never had any problems with it.. I've SEEN them break, therefore, i don't feel that its safe.. (plus, its not legal to run them in my state.. 1/4 inch or about a 6.25mm SPACER is the legal limit)

Further, that being said, by giving out that kind of information, i would feel partially liable if something were to happen to somebodys car after he put adatpers on those wheels, maybe not legally, but morally at least. And I've got enough to worry about as it is!!!

 

i take it that this is the wront time to ask a wheel question?

 

holy **** yearsofdecay...im not trying to start a damn battle....chill out alright?!

adapters not safe....well its mostly not safe for people who are stupid about it. im not worried about it because im **** about everything and cant stand half ***, only perfection. trust me, im not going to put them on and never check them for the rest of my life.

whole physices point, yeah...your right. not arguing there. the only thing im saying there is this would make my stance wider wouldnt it? although
it is , doesnt it weigh each other out?

ok first off, i cant stand my ******* 7 inch wide tiburon wheels that are too bling bling for my car, and the fact that they can only stand skinny *** tires. obviously, they do need to look good, or how the hell would companies like volk stay in business? we could all just find steelies from the junkyard and put wide tires on them if it wasnt the case. i was mostly doing it because i was getting more traction out of it with wider tires, the wheels were cheap and couldnt pass it up, and yes......finally looks.....SORRY!

honestly...i wasnt trying to be mean about the political thing. i actually dont really care for bush or kerry like you. you just acted like every single thing you said WAS indeed right and everything has to go your way, like most democrats. truely sorry for this one.

trust me...i understand where you are coming from for all the risks you are thinking of. not in a mean way, because i completely believe you, do you have the link for the broken adapters? because i want to see what kind of damage happened. i would really like to stop all this fuss and just get some true info to help me. i dont see why you have to get all on my case (im freeking 15.....give me a damn break!) when a crap load of others use adapters too. well....sorry yearsofdecay. settling it here..........

 

We're still here, but I won't answer some of the questions because YearsOfDecay nailed it on the head - we don't wanna be responsible if something goes wrong.


-Ted

 

trust me...i would never even think of blaming someone else because they told me i need a so and so then something went wrong.

 

I may have been a bit abrasve bud.... but you also never mentioned that you already bought the wheels... It seemed like you were asking our advice and then after i said they wont fit.. you were saying F-you.. I'm going to buy them anyway so your an ******* if you don't tell me how to make it work.

Look...

On the front you need about a 32mm offset to run a 225 tire.....
on the rears.. a a 30-35 mm offset will work for a 245 tire on an 8.5 inch wheel... 35mm will give you clearance to the swingarm incase you want to step to a 255 later... 30 should flush it up to the outer fender without rubbing with a 245, a 255 will be close but should also make it under the fender depending on the tire.

subtract those numbers from your offset numbers and then go to a local performance shop and tell them what you need to make it work. Hopefully, you will get someone who knows his head from his *** and can explain your options to you without causing even more confusion...

Again.... I'm not reccomending anything.... If the guy at the parts shop thinks it'll fly, then at least you can blame his *** if something takes a crap on you!!! (you might not blame ME.... but i'd still fell like **** if you put adapters on your car after I told you to go ahead and do it and then you ended up a "Timmahy" after a head on collision with a tree when your wheel fell off on a corner.. get it?")

I still think you should sell those wheels, and buy a set that fits when you can get the money. Patience young Jedi... Patience... but... I also remeber what i was like to be 15 and want to be cool. I gave up on being cool long ago.. I'm old, fat and the hair on my head is retreating to my back and fighting for the buttcrack army now.. It must have been that French shampoo i used to use....

 

Hey, someone should make a chart or soemthing, i would but im a dumbass.

something like this:

wheel size lowest offset highest offset biggest tire

15x6.5 ? ? ?

15x7.0 ? ?

15x7.5

.
.
.
16x6.5
.
17
.
18 just an idea...


if that doesnt work out will a 17x7.5 +40 fit for the front, what tire size should i get? not sure what the offset is for the rear ones.


Thanks,
Danny

 

I'm working on it... but theres a LOT of info and tire choices to go through... I'll have an excel spreadsheet out in a couple of weeks.

I have 17X7.5 +38 on the front... I have a 215/45/17 Kuhmo MX on the rims.. got maybe 10-12 mm to spare... so it should work with MOST 215 tires (the kuhmos have an 8.5 inch section width as measure on a 7" wheel.. on the 7.5 inch wheel, they spec out to 8.7 inches.... which pretty much keeps to the theory of .2 inches of section width for ever .5 inch over the measuring rim width.. )

 

thanks alot yearsofdecay. so would the fronts only need about a 13mm *spacer*, and not adapter (wheels are 45 offset for 7.5 fronts)? and same for the back, except a 15 mm (wheels are 50 offset for 8.5 backs)? and these would fit fine on the stock studs? thank god there are people like you to save me, i almost bought 20 and 25 mm adapters. like you said though, you dont want me to take your word on them 100%, because u dont need me coming back and blaming you if its not right completely or something happens. i had planned to take it to our friends dads tire shop for his dad to figure out all the crap just to make sure. well...thanks again man

 

..

 

18x8.5 +35 F
18x9.5 +35 R

FC3S, coilovers etc, etc, i run extended wheel studs in the rear, and with my coilovers i can clear a 17x8 +35 up front just barely...

To Fit or not to fit...that is the question !

 

i wouldnt blame anyone for the wheels not fitting. its always possible to roll fenders and get spacers. im not the type that goes around and blames people for their mistakes unlike some people you may of delt with. so just wondering if 17x9 with a 25mm offset would fit under rolled fenders with maybe 245's and if they hit the fender, there are always overfenders to fix that :p

 

Ok bud... I have no doubt that the WHEELS fit.. here's the deal.... whatever tires you are running up front now.. by adding half and inch to the wheel width, generally you will increase the tire section width by about .2 inches... thats .1 inch per side...

So assuming that you are running the SAME offset and the SAME tires on a rim that is .5 inch wider... your TIRES will extend towards the suspension by .1 inch.. If you are less than .25 inches from the suspension now.... i wouldn't chance it.. but thats me..

NOW... thats all assuming you keep the SAME make, model and size of tire... if you change the tire.. all bets are off.

 

Brilliant!
