I like your setup: 4.5" in the front and 5.5" in the rear. Are you running 185-70's in the back? I am doing the same thing on a T-6 car.
Porsche made 20-mm donut spacers for 356 cars. They were originally intended to use at the rear to maintain the track when using 20-mm wider brake drums (GT brakes) in the front.
You need longer studs to use spacers. Occasionally original 20-mm donuts show up on ebay. Several people are reproducing them; I can't remember who, sorry to say. The benefit of donuts compared to plates is lighter weight.
You may or may not have enough room at the rear to use standard-offset 5.5" rims and 20-mm spacers. If not, you have two choices: smaller spacers (thinner plates or donuts) or adjusting the offset of the wheels. Many shops can re-weld steel wheels to customize the offset.
One potential benefit of customizing offset is you have some influence over dish. Some people like the deep-dish look; others like the standard look (most or all of the extra inch is on the inside).
Thanks. I think I'm going to try the 20mm spacers. Still strange the 5.5 inch wheels don't fit. Even my 356 specialist in The Netherlands has never seen this.
I will let you know if this is the solution (and enough room between the wheels and body).
There is no such thing as a "original" 5 1/2 X 15 Lemmerz or KPZ wheel for a drum brake car. You have a set of modified wheels.
"Factory" 20mm "doughnut" spacers were produced for Carrera GT cars that had 60mm wide front drums as you stated. The wheels (15 x 4 1/2aluminum/sheel) that accompanied them had an extra 20mm of back spacing to keep the track the same as a regular car. The 20mm doughnuts were added to the rear drums to keep the track the same as the front when using the aluminum/steel wheels. Adding a 20mm spacer to your wheels is just going to cause other problems.
