Before looks like a stock C2S. I’m sure I have something...

I went with the World Motorsport, they claim they are Porsche PCA track day approved whatever that means, made me feel better, probably means nothing.

Yea so install was pretty seamless. The biggest PITA as always is the stupid brake wear sensors. Should have just deleted them.

Front was totally plug and play with the GT3/991.2 S+ front pad.

Rear needed the 11mm spacers and longer bolts from Freddy's kit (lewisspeedinnovations@gmail.com), but went on easy and torqued with no issues.

Haven't had a chance to take it for a test drive/bed the pads in yet... maybe in an hour or so once the baby goes to bed. Have a Porsche Road Rally on Sunday, hoping to get to try them out a bit then.

If you are doing rotors anyway, I can't see a reason not to upgrade to the 350/350 setup as it doesn't really cost much more money, looks a lot better, and I expect braking to be improved some too.

Interesting. Both those and the acer are 6ALV4 Rated, and look exactly the same lol:

I am pretty paranoid though about techs using impact wrenches on them though. Are you applying anti sieze as well?

I would almost bet the World Motorsport bolts are the Acer Bolts now that I did some research... Acer being the manufacturer.

Would rather not use anti seize if I can avoid it. Does Titanium have galling issues against aluminum wheels or steel hubs?
