17x8 +40 wheels with 235/45/17's all around?
What about 17x7.5 +32 with the same size tires? I'm sure the rear won't be a problem but the 235 width tires look a little big to clear in the front

Black91n/a

17x8 +40, no way, way too close to the suspension. 235/45/17's are a little tall, 235/40/17's are a better fit, and will leave more room to minimize the risks of rubbing.

The 17x7.5 +32's are about about optimal, but I don't think 235/40/17's are reccomended to go on a wheel narrower than a 8". 225/45/17's leave more room, and shouldn't rub at all with that wheel. You should be able to fit a 235/40/17 with that offset, but it's not guaranteed (depends on the actual tire, and the suspension used).

man, there's so many pages here... i think the info should be consolidated into a simple chart. Anyways; my friend is running 18x11 in the rear and 17x10 or 9 in the front. He has Tein springs and he rolled both fenders I believe. I don't know what size tires he has, but the rims are Volk GTU-S. He said he doesn't rub at all, not even on hard bumps.

My question is, I plan on running wider fenders on all 4. I was originally planning on running 17x10 in the rear and 17x9 up in front, but since my friend isn't rubbing at all, i'm thiniking about running 17x11 rear and 17x10 up front.

What would be the ideal offsets and tire sizes for this setup? Also, would it be a good idea to go as wide as 11 in the rear and 10 up front. I also have Tein S-tech springs.

A sticky thread with a chart or something like that would be a nice idea.Trying to find something in this thread is almost pointless due to it's size.

what size fenders? and how aggressive of fitment? as for running 10/11's vs. 9/10, depends what size tires you want and what kind of look you want (stretch, or no stretch), etc.

red_s5_fc3s

The fenders I'm looking at would increase the front by 20 mm and the rear 30 mm. I don't want to run crazy camber, and the tires i want slightly stretched.

kaneohe96744

ok so im wondering what do you think about these rims?

gram lights 57pro's
17x9 +12, 25, 27, 30, 35, or 40mm offset. *front*
17x10 +12, 25, or 35mm offset. *rear*

which offset would i need to run these on my FC with just eibach springs on them?
would i need spacers or rolling of the fenders?
as far as tires, im thinking 225.40's?
any info would be helpfull..thanks +1

Bigretardhead

for a more normal amount of rubber... with 17x9's, for a real slight stretch, I'd do something like +12 for the fronts with a 235/40. for the rears with 17x10's, around the same offset... with a 255/40 should fit nicely with not much camber... if the fenders are actually 30mm wider. if they're like the raceonusa fenders, you'll need a bit lower offset, as I hear those are actually more like 50mm fenders...

if you want wider tires then that, on the 10/11 wheel combo.... I'd have to figure it out....

Bigretardhead

+25 front +35 rear should work for a more normal fit. you might have to roll the fenders a bit in front. if you want a more normal fitting tire that would work with the stock fenders, do 235/40 front, 255 or 265 rear. they will still be a 'little' stretched, but about as normal as you can get with those wheel sizes and stock fenders.
225/40 tires will be bit stretched on the 9's... I wouldn't do em' on the 10's unless you really want something crazy.... which would be best with more aggressive offsets like:
+12 front, +25 rear, or +12 rear if you want to pull the hell out of the fenders. fronts should barely tuck under the fronts with ~ 2 degrees camber and a 215/40 tire - the wheel will stick out a bit and the tire tucking in. for the rears, +25 with a 235 tire should fit under stock, just rolled fenders. +12, you'll have to pull em' out a bit and the 235 should tuck in nicely or 225/40 if you want a HUGE stretch... which would be pretty tough to mount...

for a fairly agressive setup ~ +25 front 225/40. +25 rear 245/40 tire. they're going to be a little bit stretched, and tuck under the stock fenders it they're rolled. won't quire too much work and should look good.

red_s5_fc3s

Thanks for the info. I was actually looking at the Raceon fenders, so you say they're actually 50 mm rear? That means that I could probably go with the 10/11 combo, or even a 9/11 combo, right?

Bigretardhead

not sure exactly, but something like that. there was a guy I think on this forum with them and said they were a bit wider than 30mm. I think he said closer to 50mm.
he had I believe 17x10 +12 wheels with 255/40 tires, and they sat in a little bit from the fender still.

owen is fat

wow this thread is hella long!

Hey Guys will these fit Bolts fit these rims

Black91n/a

It depends. If they're M12x1.5 and you're using stock studs then those NUTS (not bolts) will most likely fit. With longer studs then they might bottom out and not fit, if the threads on them doesn't match the studs then they wont fit.

RETed

Those lug nuts look like anodized aluminum.
There's not reason to run those things on the street...unless you're doing it for looks?

Well things didn't go all as plain with the vert rims. But it's all good with me and john from San Deigo who i bought the rims from Good Guy Good Buy. I actually got the 86-87.5 GXL/Sport 15x6: rim he painted the rims white here's some pics. Of the Kumho Ecsta AST 225/50-15. Also i wuz lucky they don't rub and great just fine with the ste up. The back is ah lil high on the Stock suspension

Need some advise. I know that mustang rims theoretically fit fine on FC's. But I just wanted to be totally sure atleast because they are pretty damn wide.

The rims themselves are:

Wheel Size: 17x10.5"
Wheel Offset: +28mm (1.10")
Bolt Pattern: 5 x 4.5 inch (5x114.3mm)


Wheel Size: 17x9"
Wheel Offset: +24mm (.94")
Bolt Pattern: 5 x 4.5 inch (5x114.3mm)


Does that look good or are they too wide or the offset too much?

Also what tires can I run on the front and the back? I have no problem rolling any fenders or getting spacers.

Thanks in advance guys,

Ark

Black91n/a

Too damned wide!!!

The rears will need some spacers (~15mm) and wider fenders, the fronts will require about a 10mm spacer and wider fenders.

The mustang wheels that fit are the 17x8's, they fit just fine without the need for wide fenders, spacers or anything like that.

Why do you want to go so wide anyway? It's not needed for the street, and a stagger will most likely make it an understeering pig.

I see ,the only reason I actually considered there were because they were cheap. I kind of figured they were too wide but wanted to make sure. Regardless they are sold now so its cool.

Thanks for the help.

Bigretardhead

do you know what you're saying? I disagree 100%.
first, depends on what tire size he wants to run. definetly wouldn't need even close to a 15mm spacer for the rear, if any at all. if you run a smaller tire, you should be able to fit the rears under the stock fenders with those offsets, if you pull out the fenders a bit. I'd think you could probably do a 265 tire if you pull the fenders just a little. it would be a little stretch, but you should be able to make it work. or you could do wide fenders and go with a bigger tire. you might need a little of a spacer if you go a lot bigger, but I think with a +28 offset, you should be able to clear at least a 285 tire on the inside. (that wouldn't clear the fenders at all though).

you might need like a 3-5mm spacer in front. depending on what tire size you want to run, although I think you could probably run a 235 on those with no spacers, and just barely squeeze them in the stock rolled fenders. but it'd be really close to the suspension... might need a couple mm spacer, depending on your suspension setup... and a little more if you want to run a bigger tire, and then you'd need wide fenders as well.

but if you really wanted to get them and use the stock fenders, you could probably run a 235/265 tire combo (still within the recommended wheel widths by the manufacturer) and get away with it. although it would take a little work on the fenders. it would be a pretty sick looking setup too.

and btw, you can get mustang replica wheels from discount tire, if you're still interested in them. they're really cheap, and look pretty decent.

RETed

This is my take on these wheels...
I assume the top set is for the rear...
Offset is a little too deep back there.
At minimum, you'd need a 1/4" to 1/2" spacer for clearance.
I'm assuming 275 / 40 / 17 tire?
I've never seen a 285 in 17" - if there is, you'd have very limited options.

The 9.0", +24 is too tight inside for my tastes.
I'd say minimum 1/4" spacer, and it'll hit the fender well.
I'm assuming 255 / 40 / 17 tire.

If you're running hippari, YMMV...


-Ted

Bigretardhead

ted, just curious, with all the people running 275's on a +35, why do you think a 275 would need a spacer on a +28?

but I do agree, if you want to run a 255 in front with those offsets, you will need a bit of a spacer. and obviously, I don't think anyone has ever fit a 255 under the stock front fender. but do you think you might be able to fit a 245? I seem to remember someone fitting a 245 on the front on one of those 17x8 +30 mustang wheels. so on the x9 +24, it would just be a few mm farther out, so it should clear the suspension... just need a bit more of a roll/pull of the fender? no?

Finally the thread i've been looking for! I'm trying to get everything ready for a brake upgrade so I need to increase my rims to at least 17". I think i've found the rims I want and this is the necessary numbers:

first choice:
front:
17X7.5 offset +41mm; 215/45-17
rear:
17X8 offset +38mm; 215/45-17

second choice:
front & rear:
17X7 offset +40mm; 215/45-17

third choice:
front:
18X7 offset +38mm; 215/45-17
rear:
18X8 offset +40mm; 215/40-18

(I have more options to look at but I these are my top three)

Would I need any spacers for a stock suspension and fenders? I do plan on upgrading the suspension at a future point (probably after I put on the new brakes) probably an adjustable suspension and a variable rate coil over. And further down the line I will probably alter the body (still debating on whether I want to go wide body or not--leaning towards no wide body at the moment, but that might change).

Also am I correct in thinkthing that a wider foot print on the rear tires will will give me more traction when driving (giving appropriate conditions of the street)?

EDIT: would any of these setups alter the speedo read out adversly? IE: read 65 when i'm going 80? If so what Tire size whould I use on these to keep a (somewhat) accurate speedo?

Black91n/a

Personally, I'd go 17x8 all around with a ~30mm offset and 225/45/17's (hey, whatddya know, that's what I've got!). You could even go with 235/40/17's, but rubbing gets to be more probable. With coilovers you can go with wider tires still, 245's or maybe 255's. IMHO 17's are as big as looks good on an FC.

Those sizes you listed will all be pretty close to the suspension, some might rub requiring spacers. Wider rear tires will give more rear traction, leading to increased understeer. I like to have the wheels be on the wide side of the tire manufacturers reccomended wheel sizes, it'll give better grip, feel and turn in characteristics. You listed 18x7 and 215/45/17's on the same line, those tires won't fit on those wheels ;-).

You don't need big brakes unless you've got big power, slicks and are road racing. Stock brakes are more than enough, and they fit under 15's.

As long as the tire diameter doesn't change the speedo won't be affected, those sizes listed are nearly perfectly matched for diameter. A ~5% difference is usually acceptable, and most stock speedos are optimistic anyway, so a lower reading from larger tires usually just makes it more accurate.
