do you think greater heat capacity may have prevented this? or does this make you rethink your choice of pad? I tend to brake late myself. Or is ducting the answer?

Dave...I think you deserve a prize or something! To my knowledge you are indeed the first one to crack a disc since we released these kits last summer.:burnrubber:

Discs are indeed a wear item. On a car that is tracked frequently, the discs will always crack before they wear thin. Just to be clear, Dave wasn't posting to complain about the disc cracking. He was posting to say, 'Wow, these discs take a beating.' He has been intentionally pushing the limits of the brakes just to see what they could take. If you look back at his post about the CL pads and the temp strips, he was intentionally pouring as much heat as possible into his brakes. That's why he called it his, 'braking antics.' Dave is slightly warped and likes the idea of being the worst case scenario.;)

In Dave's case, if he wants to continue his 'antics,' a brake duct kit would likely bring his temps down a bit...or he could purposefully take it out of destructo mode and drive like a normal human-being. :p

Yeah, sorry if it came off as a complaint. Granted I wouldn't have had the confidence to attempt this level of abuse with the OEM brakes but if I had it would have cracked a lot earlier. It was not a complaint in any way. I PM'd Jeff before posting this telling him I needed to buy some rotors, definitely not with a complaint :) He ignored the question about my buddies E36 though.. and Jeff, his name isn't Lance.... you can answer ;)

Warped... maybe a little. The car is so slow on the straights and we run pass-anywhere rules in the higher solo groups with Chin, so I really wanted to determine two things: 1) How late could I brake if I ever felt the need to, or if I brain farted for a second and stopped being focused, and 2) if I got a point by going into the braking zone for the hairpin, how likely am I to be in taking that point by, and slowing enough to successfully and safely complete the pass.. and stay on the track surface. You need to figure that out to have that answer so this is just me continuing to experiment. If I had another 100hp I wouldn't have to bother, I could drive just like most of the Corvettes and GT3's out there.. slow in, slow out, drag race, repeat... plus people like late braking and I had a few passengers this weekend. All were amazed at how deeply the car could go before braking, and the entry and cornering speed of the car. (that's all car not driver!) Oh, catching up to GT3s on hoosiers mid way through 17 with a 20mph closing rate unexpectedly and stabbing already hot brakes probably isn't too good for heat management either........ ugh.

LOL once I'm done testing the limits I will most back down to the faster hard on the brakes, ease off, turn in method. This level of late braking isn't fast since I'm overheating the front tires (and seriously loading them) in the process, it's just data for me. I am considering ducting though, I just hate to lose the foglights (yeah yeah they are pointless but I like the way the car looks with them), might run it next to the cooler.. don't know. :shrug: Need to figure out which ones will work correctly too, since most I've seen wouldn't. I think only one kit actually functions correctly that I've seen on here. I could just make some but I don't have much free time anymore :(

Right choice! Would you be adding a brake cooling duct kit?

For several months every weekend I take these pretties out of their respective boxes, tidy them up, then couple of minutes of kiss&hugs, then put them on the shelf till next week.

Bloody winter, get the hell out of my city!

Cool picture though! And that's a lot of snow!

Oh yeah, I also figured I'd note, even with the serious abuse I threw at the brakes, they didn't fade one bit. The CL RC6E pads are very very good and handled the heat without any noticable (to me anyways) change in performance, and the AP fluid included with the Essex Comp kits also held up perfectly, and I was too busy to bleed them this time so they already had abusive track days on them :thumbup:

Confidence in braking and fade free operation under heavy abuse equals a win in my book.

Awesome photo!

@coyote @Dave-ROR

and this is happening as you watch

the good thing is you just can't get the rotor toooo hot to crack it )
and you won't even bother with the ducts hehe

I loved the people pushing the trolley bus. That's the spirit!

Mate you could start a thread, "From Russia with Love".

I lived in Praha (CZ) for a while many years ago and you're pictures remind me of that.

Anyway, back to Jeff counting the bonuses he's going to make out of Dave's late braking antics.

I had the JOY of installing the Kit on the inovate car for the modified shoot out. Everything fit PERFECT. CL 5's did the job at the track and the car did VERY well in the tests requiring brakes! Harness bar worked GREAT too! Good Job Jeff!

Yes, your Russian weather is causing some issues for us in temperate Western Europe as well.:paddle:

Tell you what; when it stops snowing I am going to have a massive track season this year:D

I think I'll do some brake cooling and I've a big urge to cut some holes in the front of the car.

Too cool to cool down Dave! :party0030:

On a side note, I wonder if ducting will solve the issue at this point. The replacement disc cost is simply hard to beat right now. Crack that 2nd set with ducting and it'll mean it's time to move onto ducted Endurance Kit! :happy0180:

Have you considered ducts pulling air from UNDERNEATH of the car, rather than in front of the car? Take a look at stock GT3/RS/Cup Car brake ducting around the control arm area for ideas.

this is what i am doing with my oil cooler!
