The Official 356Talk Forum

Hello,
Tried to find any info on the KPZ alloy wheels with ref. S637A. Nothing found until now.
Maybe one of the 356 registry member has the information I'm looking for?
Many thanks in advance...

This is my go to chart.

What is straight or scalloped on these wheels?

And a big thanks to Dave Seeland and Dick Koenig for compiling this years ago

I would like to put the chart that Adam posted in the Quick Reference page of the website. If anyone has a better image or knows where to find one, please let me know offline or post it here. I searched our document library on the website but came up empty. Thanks.

I think that article & chart was published in the volume 15 #1 356 Reg. I think we need to update this alloy/steel wheel chart. I have some wheels that are not listed on this chart. Mark.....set it up so we can add new info here on the 4cam forum.....Thanks

Bil,
Thanks for the lead. Attached is the pdf of the article. I will put a link to it in the Quick Reference section. If someone wants to redo the chart with additional information, I'll use that.

Mark......where is the "quick reference section" ?

The quick reference section will help you find it

Bil,
Martin is correct.
Just go to Technical>Technical Library>Quick Reference in the middle of the TL page. See screenshots.

OK....I found it.....but I want to add some other wheels to the list.....how?

Bil,
That’s a pdf of an old magazine from 1990. You’d have to redo the chart from scratch.

I thought the point of adding this list to the 4cam forum was so we can update and add wheels that are not listed.??

I am not sure what it takes to make a living, updatable document. As this one Is just one page, couldn’t you just retype it with what you have now to add, and post that?

It seems this topic would better have been titled, "Aluminum Rim Wheels" Porsche supplied the aluminum rim, steel center wheels for their competition cars. These were almost all 4 1/2 J 15 wheels because it wasn't unitil the mid 1960s that Jim Hall discovered that wider rims had an advantage. Charley Gibson, national FM champion went on record that wider tires hurt lap times more down the straight than they helped in the corners. Jim Hall wasn't seeking a cornering advantage; he was seeking a way to get the power of his Chapparal down to the ground.
There were, of course all manner of "mag" wheels, some of which were actually magnesium, most of which were aluminum and offered no weight advantage. It seems to me that the first aluminum wheel that actually offered a performance advantage was the forged, rather than cast, Fuchs wheel which appeared in 4 1/2 width on some 1967 911s.
A few years go Stoddard announced that they were going to reproduce the 356 Porsche steel/ aluminum rim wheel but so far nothing has come of that.
