FD/ 11" rear wheels?
 

For you wheel experts:

AFAIK, a 10" wheel w/ proper offset will fit the rear of a lowered FD without a 2.25" spring setup or upgraded trailing/toe links. Correct?

That said, if one were to upgrade to the 2.25" and links, how much wider can you go? 10.5"? 11"?

This would be WITHOUT rolling the rear fenders which i consider too risky.

Just thinking ahead!

hey i'm wondering the same thing. I also want to fit 18'11's in the rear, so if you do find out tell me as well. thanx. email me at opivy_1232yahoo.com

You can't increase the backspacing like that. The first thing the wheel would hit is the trailing link, not the spring.

Rereading my post,
Perhaps i need to phrase this better:
If a 10" +51.8 offset wheel will fit the rear of a lowered, but otherwise unmodified (as in 2.5" springs or upgraded links), SO:

What modifications would be needed for a 10.5" (sounds like trailing links first)? Is 11" even posible without modifying the fenders in some way?

This is all theoretical of course because it woulds be major $$ to get 18x10.5 - 11" wheels in custom offset, but i'm bored and curious.

Volk CE28Ns come in 10.5 x 18, with 44-mm offsets. This should fit in back with no problems. 295/30-18 Sport Contact 2s would be cool, along with 9.5 x 18, 47-mm offsets for the fronts and 265/35-18 Sport Contact 2s!

Muchas gracias, SleepR1

I notice sport contacts are virtually the only tire in this size... and p-zeros. And neither comes in a 255/35/18 that would be a great compliment as they are both 25" tall.

Whats the rap on Sport Contacts? decent tire?

I thought about 10.5" & 11's also because Racing Hart CP035R's come in 18x11's. I've seen 18x10's and didn't like the fit. They went in the wheel well but not tucked bhind the lip. I like the way 255's fit, so I decided on 9.5's.

I suppose you can get a perfect from Fikse or another company that offers custom offsets, but I didn't get any replies on my thread and it was closed! :mad: :( :eek: :confused:

GoRacer,

To provide some insight to your previous question about running the same width tire on different size wheels, I believe one reason for this is perhaps how the tire "breaks away." For example, a narrower wheel should, with all things being equal, provide a more progressive break away point then the same size tire on a wider wheel. From what I understand, this is due to the fact that the tire is given a rounder profile, thus enabling the contact patch to be more "progressive" of sorts. The wider wheel with the same tire, will have a more square profile and probably break away more unpredictably. Hope this helps. Thanks.

Wonder if there is any reason that your thread was locked?

As far as this thread is concerned, I was under the impression that a 10" wide rear wheel was the limit without fender flares. Is this not so?

The Continental Contisport Contacts are OEM on some of the higher end Mercedes. They are nice tires and wear pretty well. Decent ride quality. Don't know about the track though. Don't think the customers would like me taking their cars to the track.

I don't recommend running different rim widths on the same tire sizes.

FWIW, the wider rim will increase the tire's contact patch. I'm not sure that break away characteristics are determined by the rim width, more than with the tire's rubber compound and aspect ratio (lower sidewall profiles break away more aggressively than taller profiles).

Generally you want to select an overall rim width that will be at least as wide as the widest portion of the tire's sidewall. Thus, if you were choosing a 255-mm width, which is ~10 inches, you'd choose at least a 9-inch wide nominal (tire bead-to-tire bead) rim width, which is ~10 inches in overall rim width.

Note this a general rule of thumb. Taller sidewalled tires can be mounted with narrower rim widths, while 30 adn 35-series tires NEED to be mounted on rims that are WIDE ENOUGH to keep the the sidewall sqaure.

As with a CP035...there was a post that detailed some one's FD Rx7 fitment complete with pictures, specs, offsets, etc.

Rather than flooding this forum with pic requests, I suggest buying an FD Rx7 pic CD, or surfing the internet yourself for FD Rx7 wheel pics!
