Default spaced out wheels man

I`ve bought a set of 1990 wheels for my 1987. What size spacers do I require to make them fit?

Thanks
Andy

The MAM adapters are 3/4" thick. I also have a set. You can actually get the same thing cheaper on eBay.

You might want to check all 4 wheels to see if they require the same size spacers. On the left rear I had to use a thicker spacer because the wheel inset was different. I inquired about this and was told it was common on earlier C4s because the body wasn't installed straight on some cars. I have a 3/4 spacer on one side and a 1 1/2 on the other.

I said it is a common problem with early C4s! I have different sizes on mine and you can't tell the difference when driving the car or looking at it. The only time it's noticed is when you change a tire. It doesn't seem to affect the handling, but then I'm no racer. By the way, I bought my spacers on ebay and they were more than happy to sell them that way.
