I assumed there would be washers to prevent anything from leaking on both ends of the hoses, but I guess I will see when I pull the stock lines off if there are washers on the hard pipe or not.

Better late than never, here are the washers you need for the brake lines where they mate to the car's hardlines. You need two for the front line, 4 for the mid lines and two for the rear lines. So a total of 8. They are $5 each

I ended up just buying new ST SS lines and they come with the all washers.

The rear SS line set comes with both mid and rear lines and is only $36 from AutoAnything. They drop ship from Stoptech so you are getting the same product. Rear SS lines part # 950.34527

Front kit for ST BBK is part # 950.34034

No one uses brake pad sensors on BBKs. Just zip tie it out of the way.

Thanks for the clarification just order 365/345 for my E93 how do you like yours?

I can tell you These Brembo grab unbelievably, they grab effortlessly lot harder than my OEM. Definitely an huge improvement over stock. They are overkill for a street car.

That's more a function of the brake pad. The stock brakes will lock up the tires so they'll "grab" as hard as any BBK.
The pedal may feel different with a BBK but mainly the BBK is for larger pad size and larger thermal capacity for repeated stops.
And they look bad ass.

If OP is still following, if you're not going to track, just get some Ate brake fluid. It works well and I've tracked with it many times. The wet boiling point isn't great and that's where SRF come in. Brake fluid absorbs moisture with time so the boiling point drops and the wet boiling point is the main number you should be looking at, SRF has a very high wet boiling point.
That means you can go much longer intervals before a flush, particularly for a street car. Track guys like it because it because you can go a whole season many times if you don't boil the fluids.

I use CASTROL SRF RACING brake fluid. Very happy. Tracking mty car quite often, never boiled, pedal never got soft. I flush it every spring.
