S15 with ECR33 Rear Brake Upgrade - BCM Question

[Vcapital]

Hi guys,

I am getting Project Mu front calipers and ECR33 Rears for working hand brake.

So for BMC upgrade, which master cylinder should I go after?

I have narrowed it down to BM44 from ECR33.

But I found 2 part numbers, 4601075T01 and 4601075T02. Are these the same? How can I know if it is for ABS model?

Thanks.
