Anyone on Koya wheels yet?

[slide willie]

and the offsets are?

We had 25 front and 40 rear. 40 rear is a bit low for a standard car but our has been lowered.(natural camber)

love the rims but wow thats low, do you scrape at all

This is our koya demo car, its sitting on bagged with yokohama 295 rear. and lucky was sitting at perfect position with no scrape.

Cheers willie,
Ok, I'm going to bag my car too. Going to try 19x11 +30 but will probably settle on 19x10.5 +30 in the end. I've seen that Vossen car with 20x12 +50 on bags with 305/30's and it clears fine with stock camber so the 10.5 +30 ends up within 1mm of that in terms of poke. The 11" +30 is another 6mm further out unfortunately.

This is a great example with ours stock guards with 295/35 yokohama, You wouldn't wanna come out any further otherwise you may need to have the rear guards pump.

Good stuff thanks willie! actual useable info there mate! cheers! and of course yokos are often wider than others for the same size.

[MENTION=20113]FIXR7[/MENTION] not gonna tell you how to suck eggs, cos I realise this isn't your first rodeo but -
The 6GR 11" +50 wheel, fitted with a 305 tyre needs about -2.2'degrees in the rear to avoid poke (according to Paul ex Need4Speed)
I haven't actually tried the fitment yet but I'm gonna say that anything in that width, running less offset, is gonna be pokey unless you're planning to run more negative in the rear.
So, a 12" +50 is gonna be 12.5mm further out than the 6GR and and a 10.5" +30 is gonna be 7.5mm further out than the 6GR (assuming my numbers are correct).
I could well be wrong here, just trying to prevent yet another wheel mishap.

Thanks Burkey. It's all good. These things need to be rehashed again and again so I'm glad you have input on this!
Here's the comparison between the 12" +50 vs the 11" +40.....

And now with the 10.5" +30.....

^^^^ Burkey, I reckon your numbers are correct for the 12" +50. For a 10.5" +30, it would stick out 13.65mm more than the 6GR.

I worked out before that the 6GR 11" +50 was 21.55mm further out than OEM and a Velgen 10.5" +45 was 20.2mm further out than OEM.

So if a 10.5" wheel has a +30 offset the whole 15mm will move to the outside making it 35.2mm further out than OEM and 13.65mm more than the 6GR.

Ha ha. I was a few frothies deep when I did the math and I didn't have a banana handy for scale...:doh::cheers:

Not a Koya, but while the maths is being done, what do you fellas think of a 20x10.5 +38, with a 295/35 tyre? Will the camber need to be ridiculous?

 

[FIXR7]

What's this 6GR you refer to?
If I compare to willies 20x11+40 the 10.5+30 is 3.7mm further out. Maybe too much? Except for the stretched 275?

How much camber you running willie?

This is the Project6GR wheel developed by Paul when he was at Need 4 Speed Motor Sport (N4SM).

I was considering these wheels but went for MRR350's as the rear offset was +55 which moved the wheel in 5mm as compared to the 6GR wheel at +50.

I've tried to attach a sketch I did at the time which shows the position of various wheels relative to the hub face, it's not to scale by the way. Hope it works.

Matt, I use the 11" + 50 as the benchmark because from what I can see, it's at the absolute limit of "flush"
So, the wheel you're asking about, relative to that -
Deduct 0.5"/2. (12.5mm/2)= 6.25mm more inward
Offset difference is 12mm more outward
In other words, that wheel will sit about 6mm OUTSIDE the Project6GR reference wheel.
One degree of camber is about 6mm of wheel deflection off the top of my head (if in doubt, trigonometry)

Cheers
Also, big thanks to JoshTypeX... helping me to get shit right sometimes...

Haha thanks [MENTION=21513]Burkey[/MENTION], yeah 6mm further out was my calc. So you think that's too aggressive? That'd make it like 3 degrees of camber yeah? Erkan is running that setup (different design, same specs) with a stretched 275 and camber within spec (on sportlines), probably need to see it in person to decide.

I wish they made the wheel in a +45, I'm in love with the design

 

[FIXR7]

Ok Burkey, You're saying 11" +50 is the max yet, in this thread.....
http://www.mustang6g.com/forums/showthread.php?p=1581755#post1581755
They're saying 12" +50 works with std camber and Eibach springs and also, if you see the video, air suspension.
