Best option for DD/Auto-X/Track pads

[Chad44]

Porterfield R4S. Came recommended by two instructors at my last track day and I've been very happy with them since, the R4S ~ "Race for Street" which seemed appropriate for my situation and likely yours based on your OP. Make sure you bed properly to keep them quiet as mine were squeaky until I did, now silent

The porterfield specs list them "for occasional autocross, solo and offroad use" They don't list them as a track application where prolonged heat and all that track abuse is much more severe than those other applications... any insight?

FYI Chad,
I just completed my first track day with the stock 135i Jurid pads and they did fine. Granted, Lime Rock isn't a brake intensive track, but they were hot enough to smell them after a session and I had virtually no brake fade.

Seems like we've talked about this at least 3 times on here but I'm a big fan of Performance Friction Z-Rated for street, autox, and 1 or 2 track events (per year). After a few track events, some people move up to a dedicated track pad but I've honestly never felt the need to. I consider myself an average braker, meaning there are others who brake later than I do and others who are more conservative. If you like to brake as late as possible, you might want a set of dedicated track pads.

I just changed my summer school schedule and will be very unlikely to do as much driving this summer as I had planned, so for now I will get my brakes set up and run the jurids out front, and figure out what to do with the rear... I can get performance friction for the rear, and have been thinking about it, but they don't make pads for the 135 calipers (shape 1371)... I will feel out the brake situation again once I'm settled into my school schedule, but thanks for all the suggestions. I have a pretty good idea what I'll be doing for most or all of this year, and may look at stepping things up next summer when I will be free from summer semesters.

I use Carbotech XP10 135i front track pads, Carbotech XP8 rear 330i pads. I am deciding to go a full track pad/rotor setup to minimize the brake judder that I experience on braking at freeway speeds.

The carbotechs are an amazing set of a track pads. They do squeal like crazy during street driving.LOL. One thing I never did was try the factory 135i pads on the track. Botond has me wondering if they would do well at the track now. Maybe I'll try them one session.

I never done auto-x but I would guess that you would need a brake pad that operates at low-to mid temperatures since most runs are under 1minute? Track pads usually don't fully heat up till end of 1st warmup lap and IMO be horrible auto-x pad.

PFC doesn't make 135i pads otherwise I would've tried them.

As is always with braking, the driving and braking style is important too.. I am generally a late and heavy braker, but I've never been on the track before so I'd just be making assumptions.
First things first... I need the car back from the body shop, then it's a matter of getting the brackets fitted to the car for the calipers... And so you know, I sent the ZCP rotors back as the more I read on m3 forums, the less I was willing to go with those rotors for any track use... So I got a set of m3 centric blanks or the front to give me just a little more rotor thickness(28mm vs 25mm)
