Stainless Steel Brake Lines for M2 Comp

Planning to upgrade the brake lines for my M2C. Found Goodridge, Turner Motorsport, Stoptech and ECS all have that. Prices from $106-165.... Are they pretty much the same thing? Anyone has any experience with these brands? Thanks

I've used Stoptech in the past for other vehicles. No complaints from me.

I've used Goodridge in the past and had great success with them. I am going with these on my M2 as well.

Does Goodridge have a Canadian reseller? Or do we have to order from the state? Thanks

Haven't installed any teflon + SS lines in any of my cars since 20+ years ago, so I can't speak from actual current experience.
But I'm thinking about installing lines because of a low pedal on my most recent track day at Laguna.

Update: Low pedal issue solved by switching from Ate Typ 200 to Castrol SRF. Did an event at Laguna Seca and pedal height and firmness are still fine.

This was many years ago and I bought them in the US at the time. Apparently they have a Canadian Distributor. https://marcor.ca/product-lines/goodridge/

I read somewhere that in order to do a proper bleed for the brake system, one needs to connect a diagnostic computer to run the ABS DSC pump in order to ensure that there will be absolutely no air bubbles in the system. Theoretically all the shops do this on a total system bleed. Does anyone know if this is true? Has anyone done steel lines then subsequently bled the system and found no air in the system?

I just did a bleed myself from factory fluid to Castrol SRT, so it was not a full system bleed. That being said, both of my front calipers had air in the brake lines right as I started bleeding them... has anyone seen this?

Spiegler lines are the highest quality available, and they are what we use in our complete AP Racing Competition Brake Kits. Spiegler's owner is a German engineer who owns and operates the business in Ohio. The fittings are from Switzerland, are far nicer than the competition, they have swivel fittings which takes tension out of the lines, and they have a tighter weave with a sheath over them. They are slightly more expensive than other options, but still cheaper than a set of good race pads. Spiegler also has incredibly stringent testing procedures for their lines, and they are DOT compliant. There's therefore no reason to skimp on lines. They are a critical brake component, and there are none nicer than the Spiegler ones!

Front lines for the M2 and M2 Comp= https://www.essexparts.com/spiegler-...mw-m2-m3m4-f80

Rear lines for the M2 and M2 Comp= https://www.essexparts.com/spiegler-...m4-f80-f82-f87

Had these on my Z4M (with AP racing brakes) and now on my M2. No complaints!

Do stainless steel lines make that much of a difference?

My pedal is firm when I press, but goes lower than I like, could this be the brake lines?

braided SS hoses will not make that much difference on a modern performance car with decent Kevlar flexi hoses, like BMW fit oem to F8x cars.

I noticed on the IND website they have two different listings for the Goodridge SS lines for the the M2 and M2C

M2

https://ind-distribution.com/collect...el-brake-lines

M2C / M3 / M4

https://ind-distribution.com/collect...el-brake-lines

Not sure if there is any difference between the two options

Bmw Technician told me the same for most modern German cars today. Says you need some specialized equipement, get the fluid up to some temp so flushes out easier or something...I dont recall all the details. Im curious if anyone else might chime in. Sounds like brake flush really isnt a DIY project anymore on this BMW if you want it done right.
