I ended up ordering a set of front HP10's from RaceShopper.com. $157 for the set. I guess I'll stick with factory pads for the rear... Hawk's not yet making rear pads.
Joe- I'm going to give these a shot first... I agree that if they shatter it's bad news, but I'm hoping they would have made some improvements in the last 8 years. Regardless, I'll give them a call and see what they say. Maybe next year I'll get the Pagids. I'm still in sticker shock from buying the car, the invizi-bra, the laser jammer, the track tires, etc. etc.

Are you sure about the rear pads being the same fitment? If so, I can probably get matching HT10s. Great info though, thanks!

Yup. Look at the Pagid Racing USA site and search for BMW race pads - they list the identical pads for the cars I mentioned. I actually exchanged emails with them before they put that on the website and the guy there confirmed that they're the same.

I was checking out Pagid's website and found some interesting information:
According to the chart, not only does the M3 share rear pads with the M5 and M6, it has the same front pads as a 335! Does this sound right? If this is the case then front pads should not be that hard to find! Rears on the other hand...

I talked to the Hawk rep again today. Apparently there was a confirmed problem with "a few" pads coming loose from their backing plates. They have since modified their process (called "NRS", whatever that means) where they use a bunch of "fingers" coming out of the backing plate as well as their bonding agent. Apparently this worked so well that they implemented it across the board.

it does appear that the rear brakes do work harder than most cars.....my rear brakes got significantly hotter than my 928 did......but the 928 has a stupid low brake bias, so the rears don't do much....

Turner was out of stock for the Pagid RS19 fronts. I spoke with a few people and called around a bit and ordered a set of Carbotechs. I went for their medium compound (XP8) since I never got around to getting track wheels/rubber. I'm planning to use up whatever is left of the stock rubber this weekend, and then think about a track setup for next year. The guy I spoke with at Carbotech sounded friendly and informative. I'll let you guys know how the pads perform. Their pricing is reasonable: ~$350 total for the fronts and rears with BMW CCA membership discount.

Good point about the SS lines. I was wondering how they felt on the M...thanks for the input! I ran SS lines on my E36 M3's and noticed a nice improvement on feel at the track. Looks like I will get some for the new M too!

+1 on this...
Brakes are CRITICAL. Don't skimp on pads....it is not worth it. I have been tracking for 12 years now. I have tried many many brands of pads over the years. What have a I learned? You get what you pay for with brake pads. Yeah, the RS19's are expensive, but I found them to be second to none in feel, braking friction/grip, heat/fade resistance, AND wear. They will last a LONG LONG time and are friendly to the rotors. A great pad when you consider all things. Although expensive, the overall bang for the buck is well worth it. Just IMHO and my experience. I am going to stick with them. EDIT: PF pads are one of the pads I did not try in my years.....they are one of the only other pads I heard wonderful things about. I found Pagids and loved them, so I stuck with them.

just survived three days at Cal speedway with the stock pads - however the i-drive says I will need front pads at 6000 miles. I am at 3200.
MarksM recommends the Carbotech 12.

The Carbotech guy on the phone did not recommend the 12s without track rubber, so I went with the 8s. If I like their product, I'll switch to the 12s next year when I get track wheels.

I agree, but that kind of depends on how linear the price/performance relationship is. When things go non-linear, which they always do with any product, the additional performance might not make sense for the increased cost delta. $800 for pads is pretty steep, especially if you are out there mainly to have a good time as opposed to posting lap times.

It's clear the brake sensor doesn't measure brake wear, the accelerometer measures how hard you stop, then guesses at how much wear the brakes are getting. |

To the best of my knowledge, the brake sensor is a binary switch. It comes on when the pad wears out to the degree that a ground loop is broken. So you might be correct in that the system is using some other data stream to guess at what's left.

The warning light goes off when the rotor eats through the sensor. Obviously, the "life remaining" is an estimation based on some other data.

I thought I'd revive this thread with an update on the HT-10's. I did my one event last year with HT10's on the front and stock pads on the rear. Everything held up fine, and the brakes performed quite well. The problems I had were with squealing. I drove home with the HT10's still on, and about anything under 30 MPH resulted in a nasty squeal... all the way to a stop. It was embarrassing!
I reinstalled the stock pads, but the problem continued, so I took them off and applied anti-squeal. This helped a bit, but it took nearly 3 months of driving to (almost) get rid of the squeal. I don't know if the Hawk compound was incompatible with the stock compound, or if I damaged the rotors during the school, but I'm looking for a better alternative for this season. If anyone has any suggestions (pads, swapping strategy, etc.) I'm all ears. Thanks!
