I am looking for some help with a new wheel set. I am contemplating getting a new set of wheels which are only available in 19x11 +79mm. I would like to widen them via Weldcraft so I can run my current 345 tires and also so I don't have to run spacers.

I currently run 19x12 +59mm with a 5/8"(or 15mm) spacer and they sit PERFECT relative to my L5 fender edge. Taking to account the spacer, the wheels I have now would be 19x12 +44mm if the spacers were part of the wheel.

I would like the new 19x11" wheels to be widened to 19x12.5" and have the same offset as my current wheels from their current 19x12 +59mm & 5/8" spacer.

What would i need to tell Weldcraft to do in order to get this outcome? Is it as simple as sending them the wheels and telling them "Make these wheels 12.5" wide and +44mm"?

Would it be simpler to have Weldcraft make them a 19x12 and forget the extra 0.5" to get the offset I'm looking for?

Apologies if this is confusing and thanks for any help.

 

The big problem with widening, as far as i'm aware...is any additional width they add, will only add to the backspace of the wheel (inboard of the hub surface).

You are essentially looking for 4.75" of frontspace to fill out your flared fenders...that is, hub surface-to-outside of lip of wheel dimension.
The 19x11s you want have 2.85" frontspace. (massively tucked inside those huge fenders)

If you had the wheels widened, that front space dimension does not change, and if they widened them at all, you'd probably need to mini-tub the car to make them clear the inner fender well. That does nothing to fill your fenders, which is the direction you want the widening to go.


If they DO have the capability to add material outboard of the hub, have them add 2", make them 19x13", with ALL additional material added outboard the hub surface. This will get you what exactly you want. But I'm not sure they can do that.

 

thanks tom, that is a lot of help and i was hoping you'd reply.

i am not too crazy of a 13" wide wheel, though because all the pics i've seen of a 345 tire on a 13" wheel makes the tire look stretched.



i'd prefer for my tires to bulge a bit beyond the wheel like they do now with my 12"-ers which is why i thought 12.5 would be a good compromise.

i will contact Weldcraft and see if they can add the material to the frontspace of the wheel.

 

Well, there's always the 355/25/19.

 

that is true but my current rear tires have a ton of life left in them and i am planning on a straight swap.

i've just emailed weldcraft and referenced this thread so i should have some answers soon.

 

I know you would prefer not to use a spacer but (and I'm using Y2Kvert4me figures) it sound like if you added 1.5" to the front of the wheels and used a 1/2" spacer it would give you the 12.5" wheel you want with the offset you want.

If they (Weldcraft) can do that (add the 1 1/2 to the front of the wheel) maybe they can weld a 1/2" spacer to the rear and then balance the wheel and you'd have what you want.

 

^ yeah i'll have to see what they say.

worst case for me is just to have them add 1" and to have to continue to use spacers.

i'd just prefer to have my cake and eat it too.

 

Ya know Jason... A 345 on a 19 inch wheel won't look as stretched to you as my setup does on the 20. I need to lower the rear as well.:o

 

jdmvette,

I see two possible problems with those offsets. First, @ +79mm, they will sit inward 16mm more than most C5 aftermarket 11s. This will probably rub the inner liner. Actually, they will sit inward 8mm more than just bolting your C6Z06 wheels on without the spacers you're using, and some people have posted that those rub. You could try that first, and see if you have the room. Secondly, you'll need to add 2" to the front side of those wheels to have them sit in relation to the flares as your current setup, giving you a 13" wheel. I totally agree with you about the stretched look on that wide of a wheel. Actually, when I was having Weldcraft widen mine, I wanted to go 12.5". After looking at previous posts, I felt the 345 looked stretched on a 12.5 also, and looked best on a 12(in 20s anyway). Weldcraft can widen some wheels on the front side, someone just did it recently on some Z06 wheels and posted here, looked very nice(http://forums.corvetteforum.com/c5-g...s-22-8lbs.html). I'm sure James@ Weldcraft can answer those questions. In the end, I think you're looking at using a spacer no matter what with that wheel choice. If Weldcraft can add 1 1/2" to the front of those wheels, you can use a 1/2" spacer, or even the 5/8" you're using, and that should get you right about where you are now in relation to the flares, and at a 12.5" wheel(just as ljthe2nd posted above).

Here's a wheel offset calculator that really helped me with mine:

I hope this helps and doesn't make it more confusing.

hey brother, i wasn't thinking of your car specifically, it was just the first one i could find.

 

thanks for the post.

i don't have a problem running spacers if need be. i'll be happy with just an additional inch so i can run my 345 tires and space it out flush where it looks best.

 

 

why would you want you tires to stick out beyond fender????? throwing stuff on those behind you is wrong

 

i don't, but thanks so much for your post.
