17x9 wheels
 
So to start off I am not a wheel type of guy my i know nothing about this subject =)

So i have seen a few nice svt around my area with 17x9 mustang cobra reps and now i want them but i dont know where to start looking spec wise.I dont know what off set i would need or if i would need to get spacers roll or pull my fenders a bit or if i would have to adjust camber or buy something aftermarket to make this fit proper.

the one thing i know is where to buy the wheels i just dont know what offset i should be getting


thanks [ffrocks]

You should avoid 17x9 wheels like the plague. Especially those, and for a few reasons.

1) The offset is all wrong, they stick out WAY past the fenders.
2) They're heavy, upwards of 25lbs
3) You need to run 205/40/17 tires to even get them close to fitting.
4) You'll need to purchase a set of coilovers, camber plates, camber arms and adjustable toe arms... and again, that will only get them close to fitting.
5) In case you missed it before, they don't fit. 17x9 et24 is far from optimal.

good to know i would not want to invest a few hundred just to fit some wheels what whats my next option 17x8?

Nickgt40 01-08-2013 04:46 PM

Oh it would cost you the better part of $1k to get all of that suspension stuff together, and that's not including wheels and tires.

What suspension do you have now? 17x8s are definitely easier to fit but require you to be a bit lower and a lot stiffer than stock unless you're wanting to run 205 series tires.

i dont have much done but i do have it dropped with a Eibach Pro-System kit with a 1.2inch drop

Nickgt40 01-08-2013 05:35 PM

Is that as low as you're willing to go?

You can go with a 17x8 but get something et40-42 with 215/40/17 to keep from rubbing a lot. If you'd like a meatier tire, a 17x7.5 et 35 with a 215/45/17 will work too.

why do you have to go low to run a 17x8? im on factory SVT springs and had/have no problem. optimal offset for a 8 inch wide wheel would be between 41mm and 43mm. that would put the wheel as close to the inner shock as possible without rubbing the shock and it would come close to tucking it in the fenders. it still wouldnt quite tuck under the fenders though which means you would still rub a bit when you hit a bump really good. a slight rolling of the fenders would probably solve that. i just finished doing a fair bit of research into this subject because i am looking for wider wheels for better traction.

the cobra wheels you saw rolling around were likely factory 5 spoke SVT focus wheels. they are 17x7 et 45 i think.

think of offset like this. the lower the number the more the tire is going to stick out of the fender wells. the higher the number the more the wheel is going to be tucked up inside the fenders.

The factory SVT Focus wheels are ET49.

And you on stock suspension are about an inch higher than he is, so even though your spring rate isn't as high the likelihood of your tire coming into contact with the fender is less likely than his is. The idea of going lower is it will add natural camber while also increasing spring rate and ergo travel.

And I'll stick to my suggestions of ET40-42, not that there's that much difference between your suggestion, but ET43 doesn't work with some coilovers in the rear so 42 is a more universal guide to fit.

If you want to fit more wheel under your car that's great, I've got 17x8.5 ET39 wheels with spacers front and rear to ensure fitment. I run 215/40/17 tires with no issues, although I run more camber than the typical focus owner.

I run 8 up front and 9 in the rear. I do not recommend 9 unless you want to replace tires every 10k or so.

i have the stock svt rims not in love i wanted something wider with some stance to it i wouldnt mind replacing tires every 10k i dont put 10k a year on the car to begin with more like 5k just to work and home take the civic on long trips with the wife and kids i rarely use the svt for anything
