Totally stock Laguna Blue M3...stock continental tires....all I can say is..out of the box...this car is sweet. The chipped S4s...some of them..had the M3 on the straights...but only a rare few. Remember I was crusin with people like Tony C from New Dimensions (in his S4) that has some experience with making cars go pretty good on track.

Anyway, the new M3 is pretty nice on track....respect them.

I was snooping around, trying to see how other stock brake S4s were holding up at the end.

I have no warpage today after running the Porterfield R4S on stock brakes. Just a bit of grindage noise... the type that sometimes goes away on its own.

They are crumbling a bit on the front edge, are pasty white, and I used up about 1/3 of the pad. Since we only did 4 full track/hard braking, 2 15 min full track and 2 half track sessions, I wonder if they would have held up for 8 30min full track sessions. Probably not.

I was charged $379 for the set alone. Too expensive, so I'm going to double check to see if that was correct for the R4S. No wonder everyone is upgrading.

still alot for the front set though (although I have the R4-S for the stock rears).

and yeah, the price of front replacement pads for the stock brakes was reason enough for me to upgrade my front brakes.

My porterfields were totally fried...the inside two were TOTALLY gone on the right side...metal against metal...all the way back from Thunderhill...I only hit them three times total...(going into Granzella's Restaurant). It is pretty hard to drive back 160 miles from a track event..in the dark...in moderate traffic...trying to not use your brakes...try it sometime..

Don't know what to do for brakes going forward...stock pads are back on...rotors will get turned, on my dime, later this week at the place New Dimensions gets their grinding done.

Thinking of getting another set of cryogenically treated set..they worked well for me..(frozenrotors.com)

Thats all for now...nice talking to you at TH.

M3 owners usually go with PF-97s (from Performance Friction) because the Porterfields go much too quickly.

Good to see you again.

I don't think they're made for the S4

If that don't work it's time to switch. I haven't read of anyone that has done that and complained yet.

Good to see you too, and finally nice to drive at a Cali event! Thanks for taking me around the first time, and thanks to Corey for his great instruction getting me familiarized w/ Thill. Fun track! (too bad Sharon wasn't feeling well enough to attend...) :-\

Oh and definite thanks as well to Taner for the KKs! :P

Were those R4-S or their track compound?
