I can't have any wheel poke whatsoever. I've been reading and I'm really confused on what will poke out and what will not. I'm looking to get myself a set of 17x8 +38 or 17x8 +44 but not sure what to go with, please help me out. Much appreciated!

Are you on stock suspension or lowered?
Both of your posted setups will work, however 17x8 +38 will be more "flush" than +44. It will still be inside the fenders
Here are some pictures of that setup http://www.ft86club.com/forums/showthread.php?t=16850

I have STI pink springs, I'm pretty sure they drop it around 15mm, nothing major. All I really need is to be inside the fenders. Thanks for the link, I'm trying to find something that shows +38 from directly behind or from the top down!

Here are some 17x8 +42 with good sideshoots
http://www.ft86club.com/forums/showthread.php?t=13591

the 17x8 +38 will be 4mm further "out", and the 17x8 +44 will be 2mm further inside the fender.
This is on 235 tires, if you go for 225 tires you will loose about 4-5mm from the outside aswell.
So 17x8 +38 aswell as +44 work if you go for 225 tires. If you're unsure, or like wider tires, go for the +44 option.

Hope this helps

Okay that was very helpful thankyou. That +42 looked pretty much in line with the fender. I may end up going the 44.

I'm on 18x9.5+38 and I'm inside the fender without going past -1.5 camber. Why not go 17x9+38? I regret not going +36.

I dno man I don't really wanna go too wide. Plus in Australia the car modification laws are all messed up. I'm also trying to protect myself with insurance too.

1. +45 should be about flush, +35 will poke about 1cm in the front if not lowered, depending on the tires you're using. If you go for 245 in the front, again depending on the manufacturer of the tires, it might poke a bit with +45 aswell. Be carefull here, 8.5" with +45 and 245 is very very thight to the inner struits, so it may rub if you take a shitty tire that is very wide (not all 245 tires are exactly 24.5cm wide, there are differences between the manufacturers and types of tires)


For reference, this is a 245tires on 8.75" wheels with +35 all around, on stock suspenson. http://www.ft86club.com/forums/showp...1&postcount=75
You can clearly see the tires are a bit outside the fenders


2. 9.5" do even fit in the front, so my reference was for an 9.5" all around. However they do poke out quiet a bit in the front.
If you go for a staggered setup (8.5 fron 9.5rear) the car normally tends to be less agile, and rather understeers than oversteers. Also, you cannot swap the tires front/rear. Also, most wheels have a way more concave design in 9.5" than 8.5", so you'll end up with differently looking wheels. In my opinion this looks cool on a massivle wider rear car like a porsche or a Lamborghini, but not on a GT86, but this is up to personal taste.
For reference, a 8.5/9.5 staggered setup here

About springs/coilovers, see below, I'll make a special note on it at point 4.

3. Really, none. Some less grip, but take it from a guy that runs the alps regularly very spirited (here is a link to a video if you're interessted http://www.ft86club.com/forums/showthread.php?t=40789 ) anything above 245 is not needed unless you have a massive engine boost on the car. Especially if you run stock suspension

4. Suspension. If you lower the car, regardless if with springs or coilovers, the wheels will come a bit more to the "inside" of the car, due to the natural arch of the suspension. (you can see this if you jack up your car, the wheel has a natural arch due to the way its mounted to the car) So lowering the car means the wheels will move a bit inside the fenders. Normally for an 1" to 1 1/2" drop this is about 5-10mm.
If you use coilovers, you can also add some chamber to your setup, the get the wheels more inside. However, mostly this is just for looks, and extreme chamber will negativly inpact your suspension setup (the car gets less stable and less "tight" in corners) But camber and suspension setup is a whole other topic I could write a book about.


Generally, if your goal is the have an agressiv, but still usefull setup on stock suspension in 17", I would suggest the following
8.5x17 +38 or +40 or +44 wheels and 245/40/17 tires (or 235/40/17), all around (front and rear)

I'm leaving you some posts here from different setups, maybe this helps a bit to visualise my theoretical blabla above :-)

Thank you for your answers and the link references, they really helped to visualize the differences in offset with the 8.5f/9.5r staggered setup.

I will most likely be going with something between what your last two link examples were, so using this setup:

Front 17x8.5 +44, and Rear 17x9.5 +40

I will not be competing in this car.

That said, I will be taking it to track days and enrolling in a racing/learning program, and possibly doing a rally cross event or two in the future. I will be doing breaks, suspension, and engine upgrades as needed. I like the staggered look and understand that there will be some inherent under steer with this setup. I do not want to deviate too much from stock ride height or camber.

Thanks again

Widest 0 offset wheels. Only concerned with clearing unibody and coilovers. Fenders bumpers and quarter panels are not a concern for me. I can always go wider with the bodywork. I would like enough room for good suspension settings for track use camber ect. Looking at 17" or 18" options. Prefer 17" but more tires are available in 18". No stretch 295 or wider tires. Guessing 11"-11.5" wide might fit. Any feedback would be appreciated

Does anybody has photos looking down from the top of the wheel arch of 17x8 +38 with a 225 tire?

225 tires on a 9.5" wheels is also not the best idea, and in some countries even illegal, due to massive strech. 225 tires are 22.5cm wide, a 9.5" wheel is 24.1cm wide. Not only does it look bad (well, at least in my view), it also drives bad.




Well, there is a "reasonable" answer to this, and a "MAX" answer to this.

The reasonable would be 8.5" +45 to +35 offset, maybe 9" if you dont mind the front poking out a bit.

The max would be 9.5" +35, however this will poke in front and rear on stock suspension, but is possible to drive (however, dont ask me if its legal in your country.

Tirewise, on 8.5" or 9" 245 or 255 tires, on 9.5" 245 or 255 front, 265 rear

Thank you, but what if I were to go with a staggered setup: 18x8.75 with an +38 offset in the front and 18x9.5 +25 in the rears, could I/should I use a spacer in the rears to equal out the offsets? Wheel wise I'd go with 245 in the back, would the 225 work okay in the front with the smaller width or should I just grab 235's? It is stock suspension right now, but I plan on going on coil overs in the future. I'm not a fan of heavy camber so I don't plan on going that route. I've read that a slight camber is a good thing though? (Up to -3 or so)

Let me start with the tire questions first:

225 on a 8.75" wheel works, however will have a slight strech. But not as exreme as on a 9.5", so its ok. 225 or 235 does not really make that big difference, so use whatever is cheaper
245 on a 9.5" is about the same as above, a slight strech, but nothing that bad so handling will be ok aswell

Now onto the wheels:
8.75 +38 front and 9.5 +25 rear would work, but pokes if not lowered/using some bit of camber. As a reference, this is a 8.75" +35 all around setup on stock suspension http://www.ft86club.com/forums/showp...1&postcount=75 You can see it pokes rear and front. I would suggest to get 9.5" in +38 aswell, otherwise it will poke quiet a bit. Since the 9.5" is wider, it will make up for the front/rear flush issue of the twins.
So a 8.75 +38 front, and 9.5 +38 rear would make sence for the twins, however you will need a drop with some camber to not have an offroad look and also the wheels poking out a bit

As for your spacer question, a spacer lowers positive offset, so a +38 offset can be pushed to an +28 offset if you use a 10mm spacer, but not other way around (so the +25 offset is further "out" than your +38" offset, so it makes no sence to add spacers to the rear)

A sligth camber is a good thing and can add to your corner grip, extrem camber however is bad.

Hope this helps
Cheers

Sounds like a reasonable setup, just be sure to make a mild drop (around 1") as it will otherwise look very offroady and poke a bit depending on tiresizes.
Under steer will be minimal on that setup, so dont worry about it. If you like it from an optical point of view, there is nothing wrong with going staggered.

18x8.5 +38 225/40/18 On Tien Coils will this fit without fender rolling?

[choi0706]

what about using coilovers set at OE ride height, what is the widest one could go without rubbing? 949 wheels 17x9 40
