These are the original wheels off my 78 Opel Kadett. 4 wheels and tires are in great condition. 5th wheel & tire is the spare- wheel is a bit faded and tire has good tread but is old- does hold air. No centercaps. Located near Springfield, MO.

As an FYI, I believe that those "8-slot" rims are the same as the wheels that came on 1975 Manta's and Ascona's (1900's) and are 13 x 5 1/2 (vs 13 x 5). If so, they would have clearance for the 1975 "Big Brakes" rotors and calipers, that earlier OEM steel wheels do not

I did listen and wheels are now listed on an Opel sale page. Opelspyder also stated that my wheels were from a Manta or other larger Opel. These same type wheels may have been installed on other Opel models sold in the US or elsewhere but the wheels I am selling came off a 1978 Opel Kadett. The wheel size is 13x5.5. I did not state in my ad that the wheels would fit a Manta or other Opel because I cannot confirm that information. I can only confirm the size of the wheels and the original vehicle on which the wheels were installed on from the factory.

If the wheels do fit a later Opel and are a wider option that will allow the use of larger brakes, that is great and I hope someone wants them. I cannot use the wheels on my car since I installed larger front and rear brakes which require 15 or 14" wheels depending on wheel profile to clear the calipers.

Your wheels are the common sport steel wheels that were available as stock equipment or as an option depending on model in the Manta/Ascona A and B and in the Kadett C and Vauxhall Chevette and Cavalier mk 1.

No, the '73 GT Rostyle wheel is only 5" wide, not 5 1/2", has a different offset, and only has 4 slots, not 8. Similar, but very much not the same
I was also fooled on this.

The four slot 5 x 13 ET 27(or thereabouts) wheels were originally intended for the Kadett B in Europe. In Finland they are called Festival wheels after the Kadett Festival special edition. The eight slot 5,5 X 13 ET 37 were for the Ascona, Manta and Kadett C.

I am unsure about Euro Kadett B's, GT's and Manta/Ascona's Rostyle (4-slot), but I know from personal experience that the 1973 GT Rostyle rims are NOT the same as the seemingly-same Manta/Ascona Rostyle rims of the same era. I once had a 1975 Ascona SportWagon, that happened to come into my possession with two '75 8-slot 5 1/2" rims, and two pre-'75 Ascona 4-slot rims. Not only did the 4-slot rims not fit over the "Big Brakes" calipers, when I compared the Ascona's 4-slot rims to a 1973 GT rim, the offset was different. IIRC, the '73 GT Rostyles were ET+25, while the Ascona 4-slot Rostyles were ET+31 and the 8-slot rims were ET+37
