For my wife's X3, I just bought a pair of Porterfield R4S for better bite on the street and a liter on ATE 200. I got them for a decent (but not lowest) price from Zeckhausen Racing in Fairfield, NJ. I'm happy to pay a little more because Dr. Z at Zeckhausen is a great guy and will spend time to consult you and find the best brake combination for your intentions.

For my M235i, I'm probably going with the Ferodo DS2500. If I need something more aggressive, I'll get the Pagid RSL1 for the track.

Hope you find Dr. Z!

I might go with yellows, as I've seen a lot of people use them and it seems to be a good perf street/track pad

For any track event, you should've had your own mechanic do a tech inspection already. Then you must pass tech the morning of.

I can't stress enough...BRAKES, brake fluid, brakes!

Make sure you're running fresh, high boiling point brake fluid and track pads.

Street pads start melting after a few hard laps. And if they aren't, you're not braking hard enough.

i would run more like 38F 35R cold else you will destroy the PSS shoulders and even so you might still kill them with no extra camber

38F 35R cold, what would that be hot?

I would start at 32f and they will climb to 40f.

You will gain 5-6 psi depending on how you drive or even a few more...

The right way would be to use a pyrometer and see what the temperatures on different places on the tire are...
