Hey all,

i have 13"x6" wheels on the clubman, they stick out 1.75" on the front
and 2" on the back.

i want to fit group 5 euro arches.. which are 2.75" wide.

if i fit a 1" spacer to the front and 0.75" to the back is that ok??

i know it puts stress on the bearing, but how much more than say 6" deepdish without spacers, that would fill the same arch??

hope that makes sence.
Matt

I believe the mini was originally designed to have its front wheels stick out slightly more than the rear anyway. Scrap that, I think the fronts should have a wider track then the rear!

It will be ok to some extent, but making the rear track relatively narrower than the front (or more narrower as it is narrower to start with) will affect the handling. Basically it will cause more oversteer. This may or may not be a problem depending on other suspension factors.

i was only going to put a slightly small spacer on the back because the back wheels already have a built in spacer.
also i had read that a wider track at the back give more oversteer..

As you already point out, stress on the wheel bearing is going to be your main issue. As a rule I always advise customers, not to do it.

[WoMaD]

will the stress on the bearing be anymore than fitting 12"x6" Deepdish for exapmple without spacers..
as they would stick out the same amount fromt the body??

i had read that a wider track at the back give more oversteer..

Well whatever you read was wrong!

Think of your wheel as a lever. If the wheel is further away from where the bearing sits, the higher the leverage effect on it, increasing the wear rate. In the same way a long breaker bar makes it easier to exert more effort than a ratchet.
Hope that makes sense!

[WoMaD]

yeah that makes sence.

surely that means that,
if you had a wheel that has +ve offset thats 6" wide
and a wheel that has -ve offset thats also 6" wide
and the wheel with -ve offset is the same distance from the bearing as the +ve offset whell using spacers.

means the stess on the bearings are close..

not much diffrence in stress, if the outer edge of the wheel is the same distance from the body, irrelevent to the width of wheel and spacers.
weight of wheel including spacer must add some more stress tho

i might be confusing myself here..
basically is fitting spacers with a wheel with +ve offset safer, than with deepdish (-ve) wheels?

i have the group 5 arches on mine with 12 x 6 as you can see the arches just cover them up!

Put more tyre on the outside, even if you also put more on the inside and you will increase the force on the bearings when cornering. I wouldn't worry about too much though: think how much more leverage there in on the ball joints or radius arm bearings and and how much less metal they have.
