FC: Wheel Fitment Thread

I'm not trying to be an asshole I just want to know what your saying exactly. I agree with the first statement about the bearing load being in relationship to the center of the tire. After that I'm lost. This is why I stated you don't want to keep moving the wheel further and further out with spacers as the center of the tire gets further and further you are increasing the force on the bearings

Slow down and re-read.

Good stuff here lol

(Looks like some replies got edited here...)

Please take a look at the Title / Subject again.

This really has NOTHING to do with bearing load / scrub.

If you want to argue those points, START A NEW THREAD.

All you're going to do is confuse people who are just looking for FC FITMENT WHEEL INFORMATION.

As a side note, HIGH offset wheels have been proven to perform better than low offset wheels in terms of suspension (design).
This is the reason Mazda went with the high offset on the FD (8.0", +50) and why Honda went with the S2K (F 6.5", +55 / R 7.5", +65).
Suspension engineers want to stuff the scrub (center) tucked as far inside as possible for better suspension geometry.
Another strike against low-offset wheels...

why'd you delete his replies? booo i like arguing

anywho, i dont think offset itself means much of anything really. all sorts of things like hub design, brake rotor thickeness, etc can dictate the necessary offset. but yah, wishbone cars can run much higher offset wheels for really good scrub + low KIA. pick one or the other with struts..

[TitaniumTT]

Becuase we're taking a a more stringent stance on the spread of mis-information. This is a sticky and it should really only contain pertanient and CORRECT information. I also deleted all of the ramblings about wheel bearings.

Your reading comprehension is obviously lacking.

Momma always said, "If everyone in the room thinks that you are ignorant, do not open your mouth and remove all doubt."

Pictures?

You are a funny guy! First off you said I was incorrect in my post, what exactly was incorrect? Again you said you "ASSUME" his logic was simply confused. That doesn't change the fact that in his argument with TED he was wrong. 2nd in my post I had never directed my comment towards any particular person, all I had stated was not to provide incorrect info. So was I incorrect to suggest that correct info be posted, so that people that didn't understand got the right understanding?

Im gonna open this back up because i've been searching high and low for square wheel fitment specs and cant really find much (including photos).

I noticed TED had a lot to say. I found an old thread on the other forum in regard to the Roni n Speedworks wide body fenders. I currently have a slight interest in running those and did find a guy running a square set up with them but they were 12" wide and thats excessive for what im going to be doing with this car.

That being said I may just need to stick with the stock fenders and just fill them up well for the sake of practicality. Soooooo......... Here is what i want...

The widest I can go on the stock body (unless I can run the Ronin fenders and it no look stupid). 17" wheel is ideal .. maybe a 16.

My plan is that this will be primarily street driven but I do plan to get into some auto-x and hpd. I will also slay the dragon once a year.

I found this site http://www.rimsntires.com/packages.j...&req=newsearch a while ago when I considered replacing the BBSs because I thought my tire size was no longer available.

I shared that in this thread. . http://rotarycarclub.com/rotary_foru...ad.php?t=18916 which had a good conversation with helpful info.

Obviously limitations are gonna be with the stock suspension but there are options out there. If the above calculator is correct then you can use that to give you an idea of what is available from whatever wheel manufacturer. .

Thanks Zach. Obviously the stock suspension is going to be changed so that won’t really be an issue when it’s time. Thanks for those links.

By the way.... I got an email from Ronin. This is what it says:

For a square setup I'd do either

295/30r18 on 18x10.5+0 (easy fitment: the white FC on our website is mine and is basically running this)

OR

315/30r18 on 18x11+5 (more aggressive, especially fronts, some added clearancing is likely)

-Joel Payne
(for RSW)


Id prefer to run a 17” wheel so I’m unsure if simply changing the sidewall size would make a huge difference. Would it?

[infernosg]

I'd shoot for 17" wheels. Anything bigger looks strange on FC's, in my opinion. I really like the look of 16" wheels but wide tire options are hard to find. In my old setup I ran a square 16x8 +32 setup with 225/50R16 tires. That was about as wide as I could go in the front due to balancing fender and suspension clearance. A 17" wheel would have avoided the suspension (coilover locking collars, actually) due to the rim being further away from the hub.

I'm now running a square 17x9 +22 setup with 255/40R17 tires. Obviously this won't work with the stock suspension or bodywork though. I have the Shine Auto front fenders and I pulled the rear fenders somewhere around an inch. The rear would have likely fit fine with a higher offset.

Ok. That sounds good. I guess its obvious that my above post is assuming I use the Ronin fenders.... I guess we'll see what my mood is like when in comes time for that.. They look so good though.

Do you have photos of your current set up? I'd love to see it. In fact, I'd love if this thread was photos and specs.

17" tires are cheaper, and don't look 'donkish' on an FC. Our boy Jeff had 19's on his old FC. Ask him for a pic.

I never said I wanted anything other than 17". I'd prefer that or 16". The guy at Ronin just recommended what he had on his current set up. Im sure that same set up would work with 17 instead of 18.

Its the same car in my avatar. Zach has the only picture of the car left.
