You would have to post more pics of chassis and suspension so that we can tell you what car you have.

Contemporary Classics (CCX) and ERA(hi Bob!) used the 6-pin version of your wheels. I had them on my UK RAM though (and my CCX).

CCX had an elaborate adapter for the front to convert from 5-pin Jaguar PCD to 6-pin original PCD. That added some to the front track. The rear was new made up hub where the 6 pins bolted into. It replaced the Jaguar unit.

I also think you have Trigo ally rims. Approx 25 years old. I kinda recall the markings.
