Offset.. can someone help me ?

[grassy]

Hey folks,

Haven't been on the board for awhile.

Yes, we still have the Duster I passed it on to my son but due to his jobs and moving ( now Cummins - Ret CAF Dec/2022) it is still owned / stored and insured by me.. but I don't drive it now. I want him to have a garage when he takes it. Presently he is paying 2500/month for a 700 sq foot apartment on the 14th floor... anyone here from Mississauga , Ont ?

Anyway, a family member sold me a car.. it had been in storage since '86 and they sold their house in an 1.5 hours during covid and it was sitting in tall, wet grass. I was actually looking for a wooden boat built in the 50/60s to work on but the family member said it would take a few months to get back on the road Yeah, sucker. We aren't talking a lot at the moment. I have been working in it two summers now, I figure I have 3 years left.. Anyway, the question.

No one in this marque.. I mean FB pages, web sites and a rim specialist has been able to answer this question and I figure out you guys would know.

I am ready to start reassembling the car.

During my rebuild, I chose a wire wheel axle due to the condition over a steelie axle I had. It is 1.5 inches narrower than the other. I would like to go with a slightly larger tire/rim in the rear ( think Aston Martin ) and not use a spacer. My math tells me that I should be able to add another 12 degrees of offset for the 3/4 inch so I can avoid the spacer but no one can verify this.

Thoughts ?

Thanks !

Wow that is a mouthful there!

I'm not really sure where to start, but assuming the original wheels fit correctly and the new axle is 1.5" narrower. then the old wheels on the new axle will be 0.75" farther inboard than on the original axle.


So if you want the wheel to be in the same location in space you would need a wheel with 0.75" less offset.


Now I have to ask...

sold their house in an 1.5 house during covid

What is a 1.5 house?

I have been working in it two summers now, I figure I have 3 years left

You have years of work left or 3 years of life left?

Sorry, that is 1.5 hours. Site unseen by the new buyers who lived 900 miles away. I edited my post.

My SOB came with 2 different axles depending on rim choice. If you wanted wire wheels, the rear axle was 1.5 inches narrower. if you wanted steelies or rostyles, you rear axle was longer. A pic attached.

I work on my car from April to September. Last year I did most of the welding. We live in the land of rust and even though the car was put away in '86ish, it required a lot of work... not quite finished on body. This year I stripped a parts car (for bolts and missing parts) and rebuilt all the suspension, brakes, had the rad recored, went through my trans and discovered my engine (and my parts car engine) are boat anchors. Thinking it will take me 3 more years to complete and on the road. . When you are by yourself, work is slower.

Normally, my rostyle rim is has +24mm offset I want to use the offset to slide in a slighter wider rim using the offset rather than putting a spacer in place. What is the offset equivalent to the .75 ?
