From 1983? or would it need modification?

 

Doubtful

1983 RX7 Front track: 55.9"

2004+ RX8 Front track: 59.1"


Front track isn't exactly what we want to measure, but it gives a fairly telling comparison in the right area and 3" inches is a pretty significant difference. You also need to find out if the bolt pattern on the shocks is the same.

IMO by the time you modify it, it won't be worth using. But that is just my opinion.


good luck and post pics if you do it.

 

Why not just run a stock 93 strut tower brace?

 

does that one bolt right up?

 

Oh wait my bad I thought I saw 93 instead of 83. Your better of making your own then trying to make the Rx8 bar fit.
