Ran Goodridge lines on my AE86 and Miata for years with no issues at all. Not the cheapest out there, but they are worth it when my *** is on the line.

I see no reason NOT to upgrade to stainless lines if you are upgrading anyways. Besides, as savington said - on the track it's a safety issue.

Edit: I have stainless brake lines all around, and a clutch line. Very noticeable change vs the old 170k stock lines.

I'd still rather have rubber for safety reasons, unless you're willing to replace the braided lines every other season (or sooner if you race in a dusty/sandy environment). We run rubber in in with crimped connection in 300 bar applications next to 600*F coils of steel (well the really close stuff gets fire sleeve) with 280*F working fluid temps, with cyclic pressure loading.

Ah, no. I've seen several failed OEM rubber lines across several different cars. I'm sure SS line failures are out there, but in my experience, OEM lines aren't capable of withstanding the heat associated with track use.

I have both the Goodridge lines and our own lines (same mfg as FM/949). Small differences, but nothing that would make me pick one over the other, aside from the the $60 cost difference by going with our lines. The big benefit of the Goodridge lines is that they're always in stock when the other ones aren't.

Our SS lines aren't on the site yet, but they are in stock (d'oh). $95 for a full 4-wheel kit, $65 for a rear kit if you've done Wilwoods already in the front.

If you are familiar with VIR, I brake a tad after the #1 brake marker on the back straight and between #3 and #4 on the front straight.
Honestly, I wouldn't run non-SS lines on track. at 10 track days (not weekends), you are probably getting pushed by your instructor to brake harder for less time. I would most agree with Savington that its a safety upgrade. I noticed no braking difference between rubber and SS lines, so I wouldn't say night and day or any of that junk.

I am a stock hp miata, on 205 street tires (nothing) and my brakes will smoke (don't have temp strips yet :/) if I have to go into pits (or stop for a red flag) without cooling down. I can't imagine any rubber handling that type of heat cycling for longer than 2 years anyway (which is probably the suggested life of SS lines, although I am sure they will last longer), so it seems like a no brainer to me.

As for VIR-F, its not that bad on brakes, you get plenty of long straights to cool them off. braking markers sound good though, that's about where I am braking too (depending on the line you want to take into 14).

Lastly, welcome from another Raleigh miata There is a few more around here...

First I've heard of that. I live in a VERY dry/dusty environment and my SS lines look brand new, well when i clean the layer of dirt off them. Where are they going to fail? These are probably 4 years old now.

haha, is that what your instructor told you? I find cutting the grass and landing into the 15-16 straight to be quicker...At the very least, you don't have to brake!

As soon as the grit that has worked it way between the stainless braid and the teflon liner wear its way through the liner. So you'll never know until the pedal goes to the floor.

My Goodridges and most newer SS brake line kits I see have a further sheath over the SS braid.

More bad tech advice from someone who's clearly never seen the parts they're badmouthing. The SS lines that we/FM/949 sell, as well as the Godridge lines, all have clear plastic sheathing over the stainless braid to prevent this.

Do the community a favor and don't comment on parts you have no experience with, please.

The plastic cover is only delaying the inevitable, some would actually argue that its worse in lines that move since it constricts the ability of the braid to move naturally and creates more abrasion between the braid and liner, but I have never seen proof of this actually being an issue.

I went from mystery fluid/pads and 10+ year old OEM rubber lines to SS lines, SuperBlue and Axxis Ultimates and almost put myself through the windshield the first time I really stomped on the brakes.

I've used SS lines from FM and 949 with no issues, and all are sheathed. Who the hell would buy bare SS braid lines? Buy from a quality vendor (ie: not ebay) and you should be fine. I've blown up rubber lines on 2 different cars and to be honest, I'm still not sure how I survived one of the incidences.

Goddammit Andrew! Seriously, PLEASE GET YOUR WEBSITE UPDATED! I go out of my way to spend money with Trackspeed and 949 because you guys are local, even if it costs a bit more. I'm sure Emilio doesn't mind taking my money, but shipping is faster from Sunnyvale than it is from the bowels of Southern California.

As said by others, my brake lines have a plastic sheath to prevent that type of thing from happening. In fact, when I bought the brake lines I got to choose the color of sheath I wanted

Anyways, I personally would take my SS lines over any rubber lines. They are awesome.

I know it. It's priority one this winter. If there's something you're looking for, give me a call. I'll either have it, or tell you where to get it.

Don't worry, I'll PM or call you next week about the TSE oil cooler kit you don't have listed once I finish returning the fittings I already bought from Summit.

Nah, it's what Ron said as well. Basically you give up the "perfect entry" into 14 by not caring how far left you are for 14 and just dealing with it.
