Because it does poke a very tiny bit as of now as you can see If you zoom in but is very manageable to drive with. And if the 19x9.5 et 20 clears both hub and caliper the only reason for it to not fit is the width of the rim. So I'm assuming despite the same specs as my current rim, the barrel of the SDC is larger than mine in width?



Sonic Tuning
That is correct. The barrel of the SDC is much larger than most, but they needed a large barrel to be able to get the super deep concave look. If you plan on pulling your fenders or doing a custom widebody kit then yea you can fit it the, but work like that is thousands of dollars.


Thus why you haven't seen a non M car pull off all SDC yet. The only ones I've seen that ran SDC all around was a M3 with 19x9.5 et 13. Not saying it'll be impossible to do just gotta do some work on the fitment

I had the same convo with them. Wonder if we can fit regular concave up front rather than the semi concave.

I actually got my rear fenders trimmed and camber plates in the front. I got the wheels already, but im waiting for my stud conversion kit to come in so I can get everything done at once.

Companies say alot of things man. Lol. His offset in front is pretty much the exact same upfront unless there saying it will have brake clearance issues then he will be fine with the right work and adjustments.

I remember you pm'd me about a new wheel set up and I never got to reply. Pm me again if you still need my help.

When did I PM you?

and this is what forgestar told me:

Unless you have a BBK on the front the wheels will not clear so you either have to go with a lower offset or stick with Deep Concave. When it comes to concave wheels and the limitations of the brake clearance not all wheels are the same. You can run a Deep Concave on the front with a +20 and it will clear the brakes but a Super Deep Concave with a +20 will not clear because there will be no material on the mounting pad.

the minimum would be 19x9.5 et 13 from what I've seen

No doubt at the end of the day it'll probably work but considering the guys at forgestar have tried fitting it before and can say that it really doesnt work out that easily. If it was like fitting a normal 19x9.5 et 20 im sure many others would already have had the setup. When I contacted them and asked about sizing and I was talking about SDC 19x11 and 19x12 it didn't seem to even faze him yet 19x9.5 in front does

I hear you that the brake clearance could be a problem but I would of hoped he checked with them before purchasing.


And you did pm me bud you just don't remember me I think.

Also 12" on a pre LCI is very easy to fit they go right on without any real issues.

that makes no sense. why would a 9.5 inch width wheel not be the same as another 9.5 inch width wheel?? i could understand a couple millimeter differences, but that's it... a couple.

if the wheel barrel needed to be widened to make a more concave design, that means exactly what happened - the width was widened. otherwise, that's like X-brand wheel company saying "our 8.5-inch wheel is the most concave" and they use a 9.5-inch wheel but try to market it as a "really wide 8.5-inch". LOL this shit aint no tire.

p.s. - i must be the tallest 5'10" guy ever.........

They might mean internal spacing in the barrel. I know there are fitment issues with SDC because the there is less internal material on the mounting face where you bolt it up. If they say it won't fit. I would trust that it won't fit very well if at all.

I have F14's but the SDC was not out when I got mine. Anyway, the fitment they gave went on without a hitch.

Did the offsets they recommended for you fit nice and flush with no rubbing

Just to question the issue of clearing the front brakes with my 19x9.5 et 18, a et 13 will clear, so 5mm shouldn't make that big of a difference...? :/

I was told you must go lower so yes the 5mm will be a factor. Just more camber or stretch

I just checked with Pat at sonic tuning and forgestars website and they both said it clears the BBK, which is much larger than stock brakes, so I guess you were misinformed. Heres a link to forgestar's website:

It clears BBKs because the caliper gets pushed outward due to the larger rotor thus giving it more room near the hub to clear

5mm is actually a lot and can definitely make or break you in terms of fitment.

It seems like the issue is the stock brakes are too small and the back side of the spokes on the SDC won't clear the calipers. BBKs push the calipers farther out so there is more clearance with the inside of the spokes.

It's not the diameter, but the distance the caliper and rotor surface sit from the hub which causes problems. If the bbk sits further back that will be the reason that the wheels work.

Just grab a 5mm spacer and add 0.9 degrees camber to offset those 5mm.

Oh man these people listen to the companies to much and don't have faith or the know how with fitting this sort of thing.

Don't worry Gunda you know I will be there to help make these fit

See you Friday for test fitment. Lol
