Anyone know of a website that will list the what is different between a vert and a coup?

 

website? Mazda RX7 | Owners, Parts, Repair, Performance, Mods, Wheels - RX7Club.com might be able to help you ...

seriously though, what exactly do you have in mind?

mechanically, they are pretty much identical. obviously there will be body parts that won't interchange, but aside from that and a few underpinnings, they are the same car. I know the seats and wheels were Convertible only, but there's probably a longer list. however, as far as I know, those parts bolt to Coupes just fine.

misterstyx69 or Aaron Cake will likely be more well versed than I am, but you should tell us if there's a specific thing you're looking to know.

 

I have a vert and when I'm looking at part some say except vert. Just wanted to know what part are vert only or coup only

 

The parts that are labeled "convertible" fit your car, and the parts labeled "except convertible" do not fit your car. For an example, see this link:
Suspension - Spring Sets - 1986-92 Mazda RX-7 Performance Parts

There is no master list of what does or does not fit your car because each aftermarket manufacturer may make their products a little different. For example, one manufacturer may make an exhaust system that is tailored to fit only one specific car, while another aftermarket parts manufacturer may make a universal exhaust system that fits both cars.

I think that you are trying to make it more complicated than it is.

 

other than some body parts and oem suspension parts allparts are pretty much interchangeable with its couple counterparts....

 

The interior switches are a little different layout and different between S4 & S5 verts. I get the impression on my '91 vert that the instrument switch layout was patchworked together. Not nearly as elegant as the coup's.
