E30 track build suggestions

So I am in possession of an e30 325es shell. I am starting to gather parts for an engine swap that will put me in the 550-600 hp range. I also have all the parts etc for a 5 lug swap amongst other things.

So far for body reinforcement, i have purchased a turner e30 kit ( front subframe and rear sway bar reinforcements). What else can people recommend body wise so i dont break anything/ does anybody know of a good write up on this topic? I am also planning on shock tower reinforcement etc

I have done some research of this on the forums, but unfortunately people only casually mention work they have done with no real detail.
