2015+ IRS Flex Line lengths and/or part number

Hi All,

Okay, I give up. After weeks of looking thru this forum, buying stuff, returning it, buying more stuff... I'm stuck. I'm sure this info is on this forum somewhere but I can't find it.

Running a 2015+ Mustang IRS with the stock Mustang brakes for my Mk4. What are the part numbers for the flex line from the caliper to the mounting bracket. Or else, what are the suggested lengths or minimum lengths others have used successfully?

Seen these 2 mounting locations and they are where I'm targeting: Attachment 226462 Attachment 226463

Thanks for your help,

--Jay

How about taking a tape measure and see what it takes. :rolleyes:

Haha. That would be too easy. I found the tape measure method doesn't account for:
1. the extra length needed to account for wheels travelling up and down
2. just adding a few extra inches gets in the way of the shock/spring
3. The length of rigid connection and routing from the banjo bolt/caliper connection.

I was hoping someone would say... here's a p/n I've used and it worked ok, good luck.
