I remember reading a forum member on here that had their PPF cryo dipped or something of the sort. The cold temps organizes the molecules and strengthens the PPF. Not sure on the price though.

Good idea! Sounds expensive

mazdaspeed ppf are discontinued. there are a couple of companies in japan (like Makers-7) that make stronger aftermarket ones...but as far as i know, they dont deal with US orders.

I believe your referring to Rich (goodfellasfd3s). I actually bought a cryoed PPF from him since I cracked mine last year, I've been pleased with it thus far.

well i dont do any launches out of first really, i do mostly higway pulls, i do occasionally drift a little in parking lots in 1st and 2nd gear. The first time it cracked it was about halfway between th etranny and the diff in 2 different spots, almost all the way from top to bottom, and the top bracket that attaches to the top of the tranny completely broke off, so i welded those up. Now the piece that attaches to the diff broke off and it's starting to crack on the bottom support that goes to the tranny and also halfway between the two in a different spot

The PPF is designed keep the nose of the diff from moving up and down during acceleration. Some possible causes for cracks:
1) diff and/or motor mounts are shot. This puts excessive twist to the PPF
2) hard mounts, but misaligned. This would prestress the PPF, and encourage cracking
cryo is done to reduce wear, not increase strength. this is not a wear problem.

Well, I can't find the article I was talking about, but I still think that cryo treatment of a steel will increase the tensile strength. Cryo treatment definitely does increase hardness (especially in higher alloy steels) and you can generally translate increased hardness into increased tensile strength. In most steels there is a linear relationship between brinell hardness and tensile strength.
