Racing Dynamics E60s

Hello, I’ve been scouring the internet for some information on Racing Dynamics products and their involvement with the E60 platform.

I’d like to know if anyone has any information regarding what actual drivetrain modifications they might have offered for the E60 or if their cars were mostly just cosmetics and exhaust.

Reason I ask is because a beat up Racing Dynamics RS50 545i recently popped up and I’m interested in it to bring back into shape. This car is obviously almost too far gone if it’s just a cosmetic package, however if it’s one of their enlarged engines or even a supercharged one, then it’s worth the effort.

I have one of their package catalogs from back in the day in pdf too which was a pain to find. Here are some pictures:
