E30 Zone

Greetings guys!
Was currently researching for the M54 swap after considering the really light 3 liter engine (130kg) and the really high stock hp numbers.I can easily source a e46 330ci swap for like 1-2 grand in my country
So considering brakes what would be ideal to do?
Is 5 lug a must? Which setup would be safe to run but also in a budget.
Is anybody running a M54 in the forum.
Every advice-opinion appreciated

I make a single piston brake kit that is pretty much the same as what Alpina did for the E30's and these fit under 15" BBS wheels
Its 295mm diameter, 25mm thick disc
There are plenty of photos on my facebook page if you click the link in my sig
