After my last HPDE I feel like I need to upgrade my brakes. I'm considering EBC Yellowstuffs and Stoptech slotted rotors for the front, getting SS brake lines all around and upgrading the fluid to Motul 600.

I'd like to leave the rears on OEM pads and rotors as they are still covered by the maintenance plan.

Does it make sense to just upgrade the pads in the front and keep the rears OEM?

Mixing pads on the track is common. But I don’t like it.

No it doesn't. You should run same rotors and pads else you can unintentionally change the brake bias

Keep the same stock rotors and just upgrade the pads, lines and fluids.

I have the yellow stuff and they are pretty good I just leave them on for the track season and then switch back to stock at the end

That way you can still get free pads and rotors from bmw

I like EBC Yellowstuff, they've got a good bite and pad life, but they sure are abrasive pads. They will wear out your rotors after a few HPDE's

The stock calipers/rotors are sufficient. Pads, lines, and fluid will help. If you still under warranty, just swap out your fluid.... Get some more free pads while you can lol They are decent for just doing HPDE's, but once you get past "novice" you'll want something with a little more initial bite and torque. Once you get into "Race" pads like Pagid or Hawk, you'll need new slotted rotors as most of them tend to out-gas.

"Since Pagid pads tend to "out-gas" we recommend using these pads with a new gas-slotted or cross-drilled rotor for the best performance. Pagid brake pads are not compatible with previously used rotors, especially if used with a carbon or Kevlar based race pad."

1. You don't need new rotors, the stock rotors are great. Slotted doesn't make a big enough difference to prompt swapping out perfectly good rotors. Stock rotors are great and they last a very long time.
2. Yes, please change your fluid ASAP. I would do this first. You don't need the SS lines right away either. There's a chance you won't need them for quite some time.
3. Keeping the rears OEM is definitely an option. It changes the bias but that's not necessarily a bad thing. I tested carbotech XP20s on the track this week and forgot to bring my rear pads with me so I had to run the stock pads. No problem whatsoever and I may venture to say, I like it... Since I didn't have the rear track pads on hand to try them back to back, it's hard to say for sure though.

Thanks for the input everyone. I will forgo the rotors and just get front+rear pads, lines, and fluid. I can put the extra money toward an LSD

Great article, thanks. That vid of the shattering disc was cool, but also a bit sobering (at my last track day my instructor's rotors needed replacement at noon b/c they started cracking, and it made me wonder 'what would that look like if it let go while driving?').

I spun a 340 on the skid pad at the performance center and ended up in a ditch. The only thing bruised was my ego.

I made a left the other day and hit a patch of grime on a wet road in the X5 and the back end came around on me, sending me towards a parked car. Didn't even think about, fixed it, and was happily on my way with a story to tell.

If things are gonna go to shit the track is usually a good place to learn and not hurt yourself. I think something like the teen driving car control course should be mandatory to get a license.

Pretty common to run a more aggressive pad up front than in the rear. People do this that like to left foot brake while still in a turn or that tend to brake while still in a corner. I used to do it in my s2000.

I upgraded my brakes to Performance Friction -08s. Absolutely no fade.

i have the pfc08s as well, a real solid race pad. These will eat your rotors tho.
