Big Brake Kit line routing
 
So I have a dilemma. In installing my big brake kit, I noticed the included lines do not have the attachment/clip point to secure to the brake line brackets on my coilovers. Obviously concerned about them catching or snagging on the bracket (very bad). I initially thought my only option was to have a local hose supply make some lines and through trial and error and getting the attachment point in the right spot on each hose for steering and suspension movement. But, I just had a thought. Why can't I just flip the bottom tube of my shock backwards so the bracket is out of the way and facing the back of the car. I don't see this hurting anything, as I definitetly don't want to cut/grind the mount off. Thoughts? See pics. One is of an oem rubber line I had lying around for a visual on what the stock mounting solution looks like.

What big brake kit do you have?
Have you considered aftermarket stainless brake lines?

I previously had rubber coated aftermarket stainless brake lines on my car and just zip tied them in the original shock holder piece. When I removed my stainless brake lines recently (to upgrade again), they did not have any wear after 8 years. That may be an option but I can't comment on how your rubber lines would be affected and would recommend a stainless line if it's an option.

^^Looks like SS lines already, they're sheathed in plastic.

Inadvertently installed billies on the wrong sides a while ago, the bracket only moves around 45 degrees from what I recall. I think on some combinations of bump, lock and whip, you might still get contact. The Japanese use on some of their aftermarket lines something like a split rubber boot looking a bit like this ==l==, but a zip tie or those hose clamp arrangements used on shocks with no brake line provision, should be OK if you're concerned.

The shocks don't turn on the FD RX-7, so it should be even less of an issue.

The lines are braided ss. This kit: https://www.rx7club.com/group-buy-pr...000-a-1104271/
That is probably a good temporary fix, I may try a rubber sleeve or something and zip tie to the the stock shock mount. Thanks.

That's probably what I'll do, I guess I was overthinking it, and that there would be more movement, rubbing and contact than what there really will be.

What I meant there, the line retaining bracket isn't on the fore/aft centreline, but offset outboard. If you sort of rush the installation without paying full attention, bracket ends up behind the axle line instead of in front.

Sakebomb has the lines that can use the stock spring clips to retain the hose if you're anal - Goodridge source maybe - but not a possibility to install after crimped assembly. I'd personally just use some 3/8(?) split hose, pop it into the slot and zip tie with a bit of slack
