Wheel fitments

[67GT]

Hi Guys,
Has anyone fitted a 7" wide wheel on a Bellett, and if so what offset was used ?
Thanks

Hi
I am running a set of Advanti 15 x 7 with offset I think 38mm. 15 x 195 x 50 series low profile tyres
Require 'X' factor to clear calliper if running disc brakes.
Down side for mainlanders is I 'fine tune' with 5mm spacer on the rear
Cheers

they look good too...... whats the 'x' factor ?

Hi Glenn
with old fashioned mags for eg Datsun, Mitsubishi, Gemini from 70s-80's the inside of the mag is flush or flat usually.
With modern cars with huge disc brakes the central hub is recessed back in relation to the caliper so they tend to 'scollop' the face of the mag to bolt up against the hub / rotor while giving clearance for the calliper. The degree of Scolloping is referred to as 'X-Factor'

thanks for info....... is the x factor given as a measurment on modern mags.

You got me there
The Wheel man was sick of me by then asking all the questions, scratching his head wondering why I was bothering for such an old car

They just don't understand


Here is a picture of the rear and how well Asroc's wheels fill the guards
For the record a mag wheel with with tyre on is usually 1 inch larger so 7" mags actualy equate to 8" with tyres so Asroc has 8" sqeezed under her guards
Sweeeeet

very Sweeet, love the car, love the look of those wheels, seem to suit it fine.

you just need a "Bellett" strip on boot lid now......

[Asroc66]

Keeps them Guessing

[BULLITT]

put on the teardrop model boot chrome I have a spare if you want it needs rechroming cheers davo

[Asroc66]

That would be great Davo
I have a couple of the flimsy later model 'Tin' ones but just couldn't bring myself to fit it

Thanks James. I would be interested in a picture of how the front sits in the guards ( front on ) as the +38 should narrow the track I would have thought. but I guess the extra width helps in this regard. As for the rear, by running a 5mm spacer ( which as you point out we can't do up here ), that would make it a +33 in effect. All of this is good news as it does make my search for wheels a little easier. Do you get any tyre rubbing on the rear at all ?
I am actually looking at a 7" wide wheel that can be between +25 and +44 offset, drilled and machined to suit, but I need to tell them what to machine it to.

As for your question Glenn, the X-Factor is theoretical figure of no distinct value. As James said it is a term used by the wheel manufacturers in reference to the contour of the spoke.
Thanks

[Asroc66]

Your deductions are absolutely spot on
My front hubs have custom Volvo calipers and an effective machined spacing of approx 18mm out from standard so this would equate to approx offset of 20mm.
This is in keeping with Performance Supalites which are popular mags and run an offset of 18-24mm I think
Rear on Asroc 38-5mm=33mm but 15 inch is quite different to 14 inch mags in relation to clearance in rear guard
I am running 14 x 6.5 mags on rear of Bella with offset 18mm I think
So all said and done looks like 18-20mm +ve offset may be the magic figure for mags?
Best ask Toomanybelletts - Craig is the man in the know

Ps my 15's never scrub guards including full noise around Simmons Plains

[67GT]

James I am glad that I probed a little further, before getting wheels machined off your first reply. Could have been very expensive.

I guess the positive thing is that they fit the rear, which I assume is relatively standard ??!! No Jag rear end under there ?

[Asroc66]

Yep
Rear standard and yes the 15's I have pictured definitely fit well with 5mm spacers
Bellett's have very strong diffs and 1/2 shafts and nice big drums so no need to butcher
My theory is, fit the rear and the front will follow
The upright does have a taper though so stick your head under and take a look
Mags may roll nice forwards but try and turn and 'oh dear' which is why 14 inch is different to 15 inch

I've had a pair of original sedan rims widened to 7 inch for the rear of Donkey
Had them made with +29 offset and running 205 60 13 tyre, Perfect fit

If I remember, next time I'm up my brothers place I'll get them out of my shipping container and put them on a car and take a picture for you.

[Asroc66]

Here are the Magnum Dominators that I purchases specifically for 2014 Nationals
14 x 6 with offset of 20mm
Interestingly had to special order 175 x 60 x 14 tyres as 185 x 60 x 14 scrubbed big time
