Very cool evaluation of what it takes to run these cars at the track!

Looking forward to your other track mods and updates!

[LiM3y]

I don't understand how you use credit and debit here, but the message sounds about right. I am surprised you used more front tires than rear though.

[008]

You used 5 sets of front pads and 4 sets of rears in 20 hours? Which pad were you using? Was this all with the AP BBK? Are you running a duct? Street tires or Rs? TNA

[Gearhead999s]

I am also surprised about the use of more front tires than rear.I wear the rears at about twice the rate as I do fronts and I run street alignment settings.I will get about 10 hours out of an R compound tire like the RA1 if I rotate it front to rear to equalize the wear.My NT'05's lasted 8 full days which is about 20 hours of use.On a fast track like Mosport I was only a couple of tenths off what I turned on a R compound tire with twice the life.

[hhlou520]

Front tire wear vs. rear tire wear -> track layout (TWS, MSR Cresson), driving technique (I'm not smooth enough...), incorrect tire pressure (no Longacre before October), track surface heat (TX summers) might all have to do with it.
Street tires only, so far. Started out with the OEM Conti 3's, then replaced the fronts with Conti 2's, then switched over to Yokohama ADVAN Sports. Next up is a set of Hankook Ventus R-S3's.

HAWK HP+ pads with the stock set up. Mintex Xtreme Motorsport, then HAWK HPS, then Mintex F3R pads with the APs. The Mintex F3R's are here to stay - they are simply amazing.
No ducts. Yet.

Ah, I see. Yeah, you'll definitely burn through street pads quickly. Do you run the F3Rs on the street as well? try a set of PFC 01s on the track sometime.

Are you still running stock sizing?

This thread made me laugh out loud. I didn't have the foresight to keep track of nearly this much info (gallons of on-track gas? ).

+1, I had about 15 track days as well this summer on one set of PFC 01s (front and rear). There are 7-8mm left, enough for a few winter lapping days if I take it easy... Pricey, but TOTALLY worth it imho.

Like you, I wore through the front tires more quickly than rears (also street tires, RE-11s). Swapped them left and right to help mitigate the track layout effects. Are you running any camber? That helped me some... but I need more than the -2.5 up front I was had at the end of Oct. -2.0 in the rear was perfect.

15 days???? F**k me! I got 5-6 and dumped a set when the backing plate warped and cracked the pad material. There was another day left in them I reckon based on the pad thickness and rate of wear. Awesome pad though! Going to try the pagids after hawk dtc-70s (), and then choose my brand!

[dnvrdrvr]

Yep, between NASA weekends, various regional BMW CCA DEs and open lapping days... well, I was driving every track surface that was open when I was available. And to OP's point, it sure was fun

Next year: track wheels/tires + BBK (to make it easier to swap pads out) and I'll do it again. But better!

hhlou520, our NASA regional director & his wife will be splitting time between TX and the rocky mtn regions. I've been wondering if they'll do any 'mixers' between the two...?

[mastek]

Don't get those Hankooks ... get a set of BFG R1 tires

The F3R are great for medium track duty ... after that its PFC01 or Cobalt XR1

First I need to find a vendor to source the right size PFC's from. So far I've been working with Ryan from Stillen/AP Racing and he's helped me a lot to identify good pads for my braking needs.

-2.5 F & -1.3 R (I think...) I've been told before to get more aggressive with it/them.

I figure I'll be ready for these ultimate tire and pad picks early next year (I hope I'll be ready...)

Hmm, the only vendor to carry PFC 01s for our car that I'm aware of is Bimmerworld. I'd be interested to hear what you end up with as BBK is on my short list for next season & have no idea how pads work into that equation. I would guess the pads would be different depending on 4- or 6-pot configurations to accomodate the mechanics of the caliper but I really have no idea...

I know this depends somewhat (okay, largely!) on the tracks you're running. I'm planning to start mine at -3.0 F and leave the rear at -2.0 next season. -2.5 F was better than -2.0. Still not enough though and I burned the markers off the corners first day out on new fronts.

You'll be ready. I'm already itchy for a day back out there. Lack of snow here isn't helping.

Try Porterfiel-brakes.com. If you now your pad part number just send them an email. They have PFC01 for the stock calipers and carry a lot of other pad materials for bbks.
