I have a similar question. Hopefully I won't get a similar response.
Paolo92, did you get your answer?
I have a 98 cx and upgraded to ITR 5 lug. I used 99 si with rear disc like many people recommend. However, I noticed when installing the lines seemed a little long. I positioned the lines as best I could and drove it.
Fast forward 2 years:
This past weekend I started my k swap and when I pulled the wheels off I noticed the line on the driver side was kinked and the plastic outer sleeve was worn through. I never noticed any issues braking and never developed a leak, but now I am wondering. What if I would have ordered the integra lines? Are they shorter?
