O.K. First things first I did a search and found some info....but it was like a different language.... I know that im going to need some spacer/adapters but I don't know where or what kind I need. I have a 87 with the 4 bolt. the rims I got are HD Tuning (HPD PYPZ) With 205/40zR17. I was told they were off a Miata... I thought that they would fit but that wasn't the case.... There are two sets of bolt patters they measure 2 3/4" & 3". They are really nice rims that i really want to put on my car so if anyone can help that would be great. Thanks in advance

 

Miata is 4x100mm bolt spacing.
RX-7 is 4x114.3mm bolt spacing (4.5 inches)

Measure your bolt pattern on the wheels again in metric, center to center, and from colts directly across from each other. Or take them to a tire shop and have them use their tools to measure the bolt pattern.
