Maybe this has been covered already, but couldn't find it. While waiting for the green light to order a kit, I've been doing what everyone else does, read build threads, read the build manual etc. One thing I can't figure out is the difference in the front brake line routing from the MC to the T-junction on the left front. The manual has it going out the "slot" in the footbox front, down along the lower slanted tube. It seems most are running it along the upper tube, then a 90 degree bend down to the T-junction. Can't figure out why. seems the line is more "out of the way along the lower tube, and doesn't have a portion where things could "snag" on it. I think I get the cross over along the X frame instead of the location the manual has. Can someone enlighten me, what am I missing?

Thanks

I think the main thought there is the upper tube gets the brake line further away from the exhaust header. The lower tube is relatively close. Having said that, radiant heat issues to the brake line are probably a very low likelihood. But that's the reason I see the change made. And why I've done it that way too. Quick comment though. Some things about the build are very flexible and not cast in concrete. Brake line routing happens to be one of them. Use the manual as a guide for sure. But there are multiple ways as you've seen from looking at build threads. Each tailored to that builder's combination of parts and personal preference. Don't overthink it. As far as "snagging" on the brake lines, unless you're doing something unusual, pretty unlikely. Once the build is done, the brakes lines are just one of many tubes, hoses, etc. and kind of blend in with the rest. Doubt that's an issue.

I ran mine on the upper 3/4" frame. The bigger issue with header heat is the rear brake like. The manual shows the line running on the face of the DS footbox front which is usually pretty close to the headers, esp if you're using the 4 in 4s and not the J pipe. I, like many others, ran my rear line inside the footbox behind the gas pedal and drilled a hole in the floor that the line exits and then runs under the car.

Duh... thanks all, didn't even think about heat. Double shame because I did understand why so many run the rear inside the footbox.. Didn't have any issues with running it on the upper tube, was more curious than anything. And as every other set of posts I've read, help or suggestions is always near, what a great community. Some of the other Forums out there (not FF5, not even this industry) could sure take a lesson from the quality people on this board.
Thanks again
