I am getting an mk1 mx5 in december, on standard mk2 alloys. The wheels however do not have much offset they sit quite deep into the arches.
I am looking at the idea of going for reversed centre steels. The reason being i love the look of banded steels but I don't want them to be too wide on a lowish power car, I want it to retain its loose properties. I am hoping the slightly wider track will make it a bit more stable too.
Now does anyone have any experience of reversed centres, a friend of a friend had some on a k11 micra and they looked fantastic. Does anyone have any photos to show how they fill the arches. I know this can be acheived with spacers and alloys but i just love steels and they will be quite light still and is there anyone who can do them in the midlands or any for sale anywhere.
Thanks in advance.

Hmm, sounds like a good way to ruin wheel bearings to me mate.
The wheel bearings aren't designed to have that kind of load put on them, which is why the offset is the way it is.
Moving the offset will put more preassure on the outer bearing.
The only way to get dish without ruining wheel bearings is wider wheels, and the only way to acheive a wider track is to physically lengthen components, or again, wider wheels.
Hate to be a spoilsport, but unless you enjoy changing wheel bearings, I'd give it a miss.
The sport pack mini was a prime example of this.
Silly big arches, wheels that weren't really wide enough and had the offset changed to compensate.
Ate wheel bearings, from new, factory fitted feckup

Ate wheel bearings, from new, factory fitted feckup I've run my mini with 13x7 wheels for the last 4 years or more, use it in summer, park it up and leave it alone in winter, I've never change a wheel bearing. Do it! Lol |

That's because you're running deep dish with the righ offset

Thanks for the help guys. With the huge growth in deep dish wheels there must be masses of people running bigger offsets then originally supplied on the car. I understand where you ate coming from though.
Do you mean though that a narrower tyre is putting more pressure on the bearing rather than a wider tyre, as I can't get my head around the difference being much greater if the offset of the center with relation to the inner lip is the same such s on a reversed steel and a deep dish alloy.
Would wheel spacers have this same effect too.
Excuse grammar on a crappy kindle.

Cheers for the link oldspice. Does anyone do them in the midlands area?

Yeah, the narrow tyre increases the load on the bearing by moving the point of cantact for the weight of the car further out.
Wider wheels will keep the load further in, and spread it

I think the issues are getting confused here. A wider wheel does not "spread the load" on the wheel bearing. However, if your goal is to have the outer lip sit a certain distance, then a wider wheel will have a lower offset to achieve the same amount of 'poke'. Eg, if you have 8" wheels at zero offset, to make the outer edge of a 6" rim sit in the same place you need -25mm offset, which is half the difference in width.

Basically, you might wear out wheel bearings a bit quicker than normal, and you will get some unfavorable steering characteristics (mostly bump steer and tramlining, as well as a little less stability under braking on some surfaces.) Otherwise it's all going to depend how wide you go. Showing you examples of how they fill the arches on other cars isn't going to tell you much about yours, so all you can do really is work out what the final off-set of the wheels will be, and use that to work out how they'll sit in relation to your current wheels. Unless you can find someone who's done it on an MX-5 too.
They'll look cool, and a wider track width will add a touch more grip, but they won't make the car feel more stable. Because you're making the wheelbase more square, if anything it'll get twitchier on the limit.
