Brakes feel crazy soft during rain

Sounds like you need a bleed first. After that press your foot on the peddle, it should stay where it is with constant force. If is slowly moves down, you have a leak somewhere. It would probably be master cylinder or brake calipers. Check for gunk on the inside of the wheels to find the leaky caliper. Don't get brake fluid on your paint. Over time it will eat it up like paint remover.

I'm going with these brake pads! Thanks man

ME20's on a DD Road Car ???

ME20 is a full race pad and it simply won't bite at low temps. You'll travel 20 metres plus just to get the pads up to temp so they bite, which puts you 20m closer to an accident every time. MX72

If you are using them as track-day pads (only), ignore my comments.

For OP, if the pedal is falling to the floor, then replacing brake fluid and bleeding the system is the very first step ... it is a basic maintenance and safety issue.

Yup. I have just under 20k miles on them. I have no issues with stopping on cold pads, besides a slight lack of initial bite as you mentioned. That being said, I have had more than a few panic stops with cold pads, and never once have I doubted them. The Carbotech's I had before them (XP10/8's) were worse.

However, I also live within an hour of the tail of the dragon, and have driven MX72's on a Z up there more than once. They do well, but not well enough for what we can achieve up there for braking temps. So I needed something more than what an MX72 can do. Hence the ME20 purchase. I may step down to an ME22 on the rear next time around though. It has a little too much rear bite for my driving style, although I can make it work very well in certain situations.
