What size brakes needed?

[craigt-from-atl]

I'm getting all caught up in this whole 'Porsche brakes' for the beetle stuff. I just needed to get some kind of reality check. While it would be really neat to have 996 brakes on my beetle, I don't think they are necessary.

I'm still in the research/looking phase, but will be acquiring a '58-'61 Ragtop. I will shortly thereafter install a Raby 2270 Type 4. I'm not sure on the HP yet, but figure between 100 and 140. (I think)

Obviously I will need to upgrade from stock, but what is enough? I really like the idea of Porsche brakes, but am not liking the fabrication and $$ needed.

What would you guys suggest? I definitely want to go disk all the way around, and want to keep a parking brake. I have mechanical abilities, but don't have any fabrication access/abilities. Above all, I want my beetle to be safe. (at least as safe as a Type 1 can be)

Thanks.
