Offset range for 4 lug wheels?, What's the range that will work on a narrow body w/ 4 lug wheels? Options

[DC_neun_vierzehn]

As the title and description states ... I would like to understand the specs I need to be mindful of when shopping for wheel replacements on my '73 2.0 stock 914. I know my stock Fuchs (which I will keep) are 15x5.5 and have a 4x130 bolt pattern.

But what is the offset range I need to stay within or wheels?

And can I go wider than 5.5? Like 6 or 7?

Many thanks in advance. I did try to search the site for these answers, but I could not find a clear answer.

Minilite used to offer a 4x130, 6.5x15 wheel that fits without issue, front and rear. Well, maybe lips rolled on rear depending on tire choice but no pulling to fit a 7" wheel.

Fuchs offsets: 6x15 = et36 7x15 = et23. I'm guessing the minilite split the difference.. so et 30?

As mentioned, rear space is the limiting issue, so, running more than a 205 width tire will come down to other items like camber/alignment/ spring rate etc.

and a 205 tire is 40mm wider than the OEM 165.. and a Sticky 205 will jut put all those cornering forces back into the trailing arm/bushings etc.
