oops, yeah i could have messed that up, it was a while ago and i stopped worrying once i put the euro shocks.
I called up a ford dealer to confirm the part numbers that Ken sent me when I was trying to get euro shocks since ford changed the part numbers on those. He said there was a standard suspension, performance suspension, and special suspension. I think the only difference between performance and special was the shocks. I had "sport" option package's shocks in the car originally (is that the special?). and then the "performance suspension" is actually the euro shocks option?
i had no issue with the front. the "performance" (euro) shock with brown sticker just came under a different part number.
rear first gen:
Yellow dot, standard, XW4Z-18125-AA
Lavender dot, special, XW4Z-18125-BA
White dot, performance, XW4Z-18125-CA r/b 5U2Z-18V125-VA
i believe i got the white dot part for the back, so performance is euro and firmest?
