m3 e36 fia homologation

[kele]

I have an opportunity to buy very good e36 m3 3.2 and want to start building it to rally car. Car is 4 door saloon. My question is: are there any difference in 2 and 4 door regarding Fia homologation. I've heard that only 2 door coupe is homologated but I don't believe it. I have copy of homologation and there is picture of coupe but I can't find anything about 4 door, neither it can or can't. Anybody know for sure?

Thanks in advance
