I tracked at Watkins Glen - ALL Stock Brakes. 2 Days HPDE3. Front straight 130MPH, Back Straight 140 MPH- heavy high speed braking. Brakes consistently worked fine, no fade, consistent feel, decent bite. No excessive wear to Stock Rotors. NEGATIVE- ZERO pad material fronts when I got home. Literally 1/16" pad material left- very bad . Running Sport 1 so some nannies on and could feel traction control kick on front brakes in some turns. So overall stock is manageable for a basic track day but I would not push two days again.

Upgrade- so I knew I needed to upgrade Pads for next track day- went with Hawk Street/Race compound as have had good luck with Hawk on my prior car. After seeing some reports here what these pads did to stock rotors (Thanks to Savage update on destroying his stock rotors) I decided to upgrade rotors too prior to tracking. Went with DBA rotors. Observations:
1. Street- WOW are these things noisy. A high pitch squeal that will bring a tear to your eye. Likely can hear 3-4 blocks away each stop unless you get into them heavy. So OK just to get to the track but not leaving them on for more than a day. Did I mention they are loud
2. On the track- excellent. good feel. confident and consistent braking, never faded, wear on both the pad & rotor fine.
3. Did 2 day track event but this was a lower speed 2.2 mile 15 turn road course but a lot of elevation. Brake usage not as extreme as Watkins Glen.
4. This Combo worked very good for me- I could see getting 6 maybe even 8 track days out of these pads. The rotors seemed fine so expect a few seasons anyways.

Pictures below of before and after

Rear Stock Removal





Front stock removal- good use for Bud Light.<br/>5000 Miles - 2 track events & Drag Racing.<br/>Still new look & feel





Stock coming off

Hawk Pads





New installed. Note 163 lb ft front caliper bolts- wow





DBA T3 Slotted Rotors

Close up front rotor- surface very smooth





Pad face- ALL 4 corners about the same wear- seemed minor wear on pads





Pads- OK meat. These about same thickness as my stock with 5000 miles but I do not know if started same thickness





Front after





Front after track days- smooth. No ridges or noticeable wear

close up remaining Hawk pads





Good meat left on pads





close up rear





Some lines BUT very smooth no rutting





Rear Rotor- smooth, minimal wear

All original- 40 K miles. Does not have the handling characteristics of C7





Just because it's a cool pic.





Rear Hawk pad face





Hawk after track vs Stock with 5000 miles. Identical pad thickness

Pads in action...2 track days, 8 sessions, ave 10 laps each, 15 turns/lap = 1500 turns. Slower technical road course - not brake intensive. Temps- 70-80F. It was a workout physically and mentally.
Great new track in Western MA. C7 was perfect performer.

Thanks for the info on the DBA's and Hawk pads

The guy at Hawk warned me that the Street/Race pads would be very noisy, so I went with the Street 5.0 pads. Haven't put them on yet. Debating weather to use the stock rotors or not. Big reason not to is to eliminate the cooling rings, although I keep hearing about a new stock rotor that doesn't require them. Haven't seen one yet.

savage

The reason z51's come with cooling rings, the rotors are very soft! ( trash ) even the stock pads overheat them in minutes! Please take my word for this, save stock rotors for trade in or use on street only. I wish someone told me this so I would have good stock rotors at trade in time. The reason DBA's or AP's don't have cooling rings- they don't need them! If you went to the trouble of new hawk pads, go with a real rotor, you will be glad you did. I found out the hard way about z51 soft rotors.

I could not find my shout out for all the research and leg work I did for this set up , lol I still can't believe the stopping power this set up has, as hard as I try to brake late I'm still to early at higher speeds, 92 to 40mph in a blink of a eye, I can't post my runs from work but of you want to see crazy stopping power( autocross ing ) check out my Facebook page , David Savage/ 299 I live in swoyersville, pa. This should get you there.

I edited my original post to give you some kudo's- I assumed most everyone knew the post I was originally referring to. Anyways Nice Autocross videos- I've never done autocross nor observed didn't realize was that intense. Looks fun

savage

I was sent some pictures, this is what happens when you add real pads( streetrace) to z51 factory rotors. First breaking point at small autocross.

Great video - thanks for sharing!

Looks like an awesome track (except for all that rock).

Surprised they were making that much noise on the track.
