I was unaware they made them in 3mm and dont believe they do. I could be wrong as I rarely build anymore these days.
Either way, my stance on the 2mm version has been posted probably 20 times on this forum. Best steel seal on the market in my opinion. Bought an fd last week from a customer I built an engine for over 2 years ago. 13k miles on the engine, street port, with all the typical bolt-ons(full exhaust, PFC, IC,etc). Engine is still rock solid and pulls 430mmhg(17) at just below 900 rpms with a street port. Much easier on the housings than some other "unbreakable" seals.
I really cant see the need for them in 3mm as the 2mm are excellent.

2mm here, survived severe detonation on my engine, enough to crack front and rear irons. Only suffered very minor bowing of seals. Didnt realize they offered 3mm, but imagine they would only be useful for someone who already has 3mm rotors or out of spec slots. I had some minor scratching of housings after only a couple thousand KM's, but I am not convinced it was the seals.

Where have you seen these seals for sale, or was it direct from Edgar? Last time I checked they didn't make 3mm ALS seals. Closest thing would be Goopy's 3mm seals

I spoke with Edgar this week, and he confirmed that ALS does not currently sell 3mm seals. They are working on them as we speak, and will be doing some testing with the hopes to release in the coming months.
Just to clarify...

IMHO, ASL is the best of both worlds.
ps. 37psi is low boost
