19x11 Front Fitment

[tyshenry]

So, I know that 18x11 wheels can fit up front from Dusold's build. This tells me that a 19x11 should be possible. They won't say the offsets used on those wheels, pretty weak, but whatever.

Using other wheels fitment and offset's as a guide, and Toothless' 19x10.5 front fitment it seems that at 19x11 the offset would need to be somewhere between +32 and +34. This would leave a couple mm clearance between wheel and strut, I believe.

So I'm thinking that a 19x11 square setup should be possible with a +42 offset and then run a 8-10mm spacer up front. And I would be able to rotate tires.

Opinions? Facts?

Edit: 1 year and 5 months later, I finally did the 19x11 square setup. Link to thread documenting some information which we plan to add some more measurements to eventually.

I can't be the only person who wants to run square fat rubber and have the ability to rotate tires easily, can I?

I knew right away where the 18x11's you're referencing were sourced, and I don't blame them one bit for wanting to hold onto it as proprietary information.

He has no obligation to publicly provide the information that makes fitments that could be as tight as this (no, it doesn't rub, not even during track day sessions)

so that every other wheel supplier with an internet connection can have his research done for free. Fronting all of the development cost (wheels, labor time setting up and measuring, trial, error, lather, rinse, repeat) and then giving away business because of it is about as lose-lose as a business decision gets.

I won't even post a guess as to what I think the offsets might be. Or compare anybody else's guesses against mine.

You are going to want to get some fender flares or something, his wheels are very aggressive and stick out of his fender. Which would be fine if you weren't lowered a ton, otherwise you are going to rub and possibly damage your fender.

The main thing is for instance when I did the first Ag M590 square 20x10 fitment I wanted to hold onto the offsets because well truth be told I did the work I didn't want everyone to grab the info and run, but im still working on this 11" front fitment hopefully should have info on this shortly.

I respectfully disagree. The truth of the matter is that there isn't THAT much work to be done. I could tell you pretty damn quickly what the correct offset is by having a wheel with an offset that I know will hit the strut (like I stated in the first post) and then shimming until it doesn't rub. Voila, there is the correct offset for THAT wheel. Obviously every wheel will vary slightly.

More than anything I think sharing information harbors good will and shows that the company is part of the community. Personally, I think the only way to lose is by trying to hold onto that information. It isn't as if people aren't going to figure out the correct offsets and fitments eventually.

Either way, I don't care what any company chooses to do. Like I said, one way or another someone will figure it out, and maybe I'll just do it myself.


So getting back on track....I feel like going with a +42 offset wheel will allow me to use spacers to push it out just far enough not to rub. I might have to roll the front fenders a bit? I won't know till I try. And eventually when I go coilovers I should free up some inner clearance and then run a smaller spacer and pull the wheel in a bit.

Your only reason for wanting to run an 11" wide wheel is to be able to rotate a 295/305/315?

Curious why a 10" wide square setup is not wide enough if you don't plan on tracking your car like Aaron does running the 11" wide setup.

Huh? What exactly do you think I plan on doing with this car? That's absolutely why I want an 11" square setup....

I have a question. Why wouldn't I want a square 11" setup?

Okie dokie. Since your a little touchy about your post.....

Since you didn't disclose that you would be tracking your car in your initial post, I didn't assume you would be. My fault, I assumed something.

Best of luck trying to get your info....

No flame intended, but at $300/wheel (times two because the offsets have to be different) plus shipping, times the number of iterations it takes (for how many different tire sizes?) . . . plus paying the crew to actually do the work . . . adds up, and the development cost easily runs into four figures. Giving that away to a cheap imitator without selling said imitator even one set of wheels for him to copy to his heart's delight isn't good will, it's financial stupidity. Might as well put hundred dollar bills in your mailbox and stick a sign on the flag saying "don't look inside".

All anybody has to do if they want ?? x 11 wheels is get on the phone and order them.

Yes, they do stick out a bit, but I'll bet that 10 full inches of tread or a bit more will still be under the front fenders just like it is in this picture ↓↓↓ . More camber than factory preferred (also visible) will probably be in order, but then again I wouldn't expect anybody to upgrade the front wheels on a purely DD all the way up to 11's and then put 285's or wider on them. At that point it's going to be either a part-time track car or a show car with a road racing flavor.

I still think you are overstating the complexity of the problem. I already gave you a solution that isn't near as involved as what you are saying. You don't keep ordering/making wheels till it fits. You simply figure out what fits by other means.

I agree Tyshenry. Offset is a mathematical or engineering calculation. It is not some secret proprietary invention. It is no different than any other specification for the wheel, such as diameter, width, weight. If you want to sell wheels you have to tell your potential customers what the specifications are: width, diameter, weight, offset, material, finish, manufacturing process, etc. Right?

A 19 x 11 inch will work with a +29 or +30 offset in the front. That is as high an offset you can go, or you will hit the stock strut body. The +29 will have similar wheel to strut clearance as mine. The +30 is slightly less strut to wheel clearance than mine (but should still work, depending on the wheel and the lip to inside bead dimension. The tire will need to be slightly narrow for the wheel (i.e. stretched, as the tire will bulge a little past the wheel if you go too wide.

To run a square setup like that will look like crap. The back will POKE OUT a lot. So you will need to have a different offset in the rear regardless. In my honest opinion, I think the widest square setup you can run is the one I am running. Mine pokes out a little in the rear and uses all the space available in the front due to strut clearance.

My plan is to run 19x11 with a 50mm offset.

The fronts will have Cortex offset struts to clear the rim.

As far as I can tell a 305/30-19 on a 50mm offset should fit in nicely front and back, and the Cortex upgrade kills two birds with one stone, great shocks and offset strut.

Just got to sell a damn house, so I have some cash to spend.

 

[Norm Peterson]

Guys - if you don't test, you won't know if there are combinations of bump travel and steering that will cause a rub that wouldn't necessarily be obvious. The strut body and the edges of fender opening for straight-ahead driving are the easy ones.

Alternatively, you supply wheels that are narrower than what's possible with conservative offsets (*cough* AM, Tire Rack . . .), which fortunately or otherwise is a good enough solution for the majority of customers.

I'm not in the wheel business, but I do have a bit of experience fitting unusually wide wheels. Developed my own tire & wheel comparator, even.
