I got a set from partsgeek. Slightly more expensive than the sebro drilled but still pretty cheap. Haven't installed them yet so can't comment on lifespan/quality.

Yes, "light" is right. Despite the fact that they have left/right orientation, the cooling is no better than the stock drilled rotors in my experience: https://rennlist.com/forums/987-981-...l#post15209219

They are also 3 pounds heavier than stock, but they don't crack as easily.

You're also missing the fact that they are larger in diameter which offers more brake torque for the same pressure. This in combination with the improved cooling meant I've never experienced the fade I used to get with my 996 in my 987.2. I've also never felt the need to change the master cylinder for the same reasons.

Yes, I replaced the OE drilled rotors with slotted Sebros as one of my first steps, but they didn't help the overheating I was experiencing on track. Totally fine for street. Even extremely aggressive street. I didn't notice the weight by feel while driving. Just by measuring what went on and what came off of the car. That's 3 pounds for all four corners.

That sounds more reasonable.

I imagine they are fine for track for most. Better than OEM due to the cracking issues with drilled rotors. Overheating at the track depends on lots of factors, driver, track, etc. I have a buddy I used to run with regularly with at the track. We had basically identical car set-ups and ran almost identical lap times (I was slightly faster usually). He went through brakes more than 2x as fast as I did (same set-up) and battled overheating. I never had any brake overheating issues.

I just did a track day Saturday and can confirm increased durability with the Girodiscs. The surface still feels almost perfectly flat with almost no grooves or unevenness. The only thing that shows is discoloring from the heat.

It seems that way. For example, at the Fontana Roval I had no trouble doing ~130 - ~40 for turn 3 all day long, but always had problems at Lagua Seca where I go the most. I think the difference is there's more distance between the hard braking zones at Fontana that gives the brakes time to cool. In any case my local shop says lots of 987.2 owners complain about overheating brakes at Laguna Seca, and Sharkwerks even has an article up about the "notorious" pedal feel problem: http://sharkwerks.com/porsche/987-ca...r-upgrade.html

Out of curiosity, can you divulge what the differences were between your buddy and yourself on the track? Was it as simple as pedal effort?

In my opinion he over-drove the car. He was on the brakes too much, did a lot of trail braking and wasn't a very smooth driver with his inputs (he wore his tires more than me as well). He made up for a lot of it with being very aggressive and having excellent car control when the car started to slide/need correction. If you rode with him, then rode with me you would think he was significantly faster as riding with him was a bit of a "thrill ride". The reality was our lap times were comparable and we had a great time driving together.

We also have the Sebro Slotted in stock too.
