I track my Z06 every couple of weeks and was wondering what improvement if any I can expect with brake cooling ducts. Are they a help or hinderance keeping brake fluid temps down?

great bang for the buck track mod, I put the quantum motorsports kit on both my vettes. Another step up is removing the fog lights for a front feed setup, pictures were posted a short while on doing this mod to improve from the bottom feed setup on the c6z.

Foglite brake ducts have worked great!! 10 25-30 minute sessions so far with NOT A SINGLE brake bleed!!!

Another option for you here...

run them both with Cobalt pads and Coleman rotors and you will NEVER have heat problems again....with the brakes.

That's the thread! Great job with that btw! -Dan

Thanx guys,
I asked the question because I've had real problems with boiling fluid. Lost the brakes at 140+ mph last wknd. (had to change my undies) Got 2 pc. rotors and I'll certainly go with the ducts and foglight ducting mod, which BTW is a great write-up. Also installing DRM S.S. caliper pistons. I sure hope that this problem gets resolved, Those big 6 piston calipers should be able to get the job done.

you will be fine with the above set-up. add one more thing. Castrol SRF fluid. It seems pricey at first, but how much is your time worth?

I have not needed to bleed brakes all season so far.

secondly, Talk to Robert at performance AFX on rotors. I ran his 2 piece units and cobalt 1 piece pads for the stock C6Z caliper for an entire season ( and then some) ..that was BEFORE my foglite brake duct mod.

Zip products and Finspeed are both carrying the AFX rotors. What makes them great is ...

1) The coleman steel ring

2) Robert machines the CNC aluminum hats in house and is quite proud of Them ( he should be!)

3) when it comes time to add Rear 2 piece, you will have a parking brake AND not have to add a little shim in between the claiper and spindle every time you swap pads.

damn, I should get some product sponsorship for all these plugs; Actually, I'm just happy to have a product that works.

P.M. me if you have any ?'s....Good Luck!

Are you saying you got a full season from one set of rotors and pads?

Details??

2muchhp

Yeah me too. Full season for me was 6 track days. When I took off the rotors at end of last season I had about 1/2 the Cobalt pad thickness left, but about 2 track days on the rotors left.

So how I know that is I ran 2 track days this year and then replaced the rotors (not the hats) from Performance AFX.

I just returned from 2 more flawless days at Autobahn so they were a real confidence builder ans very smooth on the course.

bowtiguy

yes I did.

(8) 30 minute sessions at Road America 8/08 with the NCM

(8) 30 minute sessions at High planes raceway

(8) 30 minute sessions at Colorado State Patrol test track

(4) 3 lap sessions at PPIR for the NCCC convention

(4) AUTO X laps at PPIR for NCCC convention

and a few others I can't remeber. AT LEAST 12 hrs of track time.

Stock claipers, AFX/coleman rotors/hats, cobalt 15.2mm thick XR-2 one piece pads, LG spindle ducts tying to stock C6Z bottom feeder inlets , SS lines and motul brake fluid.

I made the mistake of trying to run the Cobalt CSR pads over the winter 08-09 and the pads caught up on the padlet pins and created pad drag and accelerated wear of BOTH rotor and CSR pads.

* make sure you keep those pins clean when using 1 piece pads.

If it wasn't for that, I think I would have been able to run this set-up for another 3 months with just new front pads.

Zip Corvettes

Yes you will get a full season if not more than longer than that. Back in 04 when we were developing these we ran them on a WC C5 all season with no issues. The pads did not go that long, but they were not Cobalt pads either, but the rotors went all season. The very first set pulled a double at VIR and they were drilled with NO issue what so ever. I don't drill them anymore except for special applications, but they are extremely durable rotors. Plus in the rear you will get to keep your parking brakes, RIGHT ROBERT I guess I have to take the kudos for that one. But you will not be disappointed. If you are going to the VIR event at the end of June I will have them there for sale and we can install them for you there.
Thanks

x2 on the SRF fluid, I ran ATE Blue on the c5, good stuff, SRF seems much better though.

i have tried a lot of combinations of pads and rotors.

I finally decided that the stock rotors at $89 each and getting 3-5 normal sessions were cheap enough and functional enough to use as a totally disposal item....... sorta like gas.

As for pads I have tried every type I think and can't get more than 2.5 to 3 days. Most of my track days are at Mosport which is not particularly hard on brakes....in theory at least... for instance the CarboTech one piece have given me one day at mosport and 1.5 days at Watkins Glen so far.
I will switch the front pads side to side and get one more day for sure maybe 2.

What are we looking at for a front axle set up as you are using? $?
I find the rears last pretty well with stock rotors and any pad so not too concerned about them.

davidfarmer

Are you sure you are having fluid problems?? Pad fade is more common than fluid boiling.

I only cooked the OEM brakes once in the C6Z, and it as giving back-to-back "fun" rides at CMP with not cooling.......the brake ducts caught on fire in the process also.

Adam@Amp'dAutosport.com

Carbotech has been in testing with other brake pad mfg and has shown a significant decrease in brake fluid temps vs other mfg

STANG KILLA SS

given similar compounds/performance/bite, the heat created by friction with be virtually the same, ie a constant. also heat transfer from pad to piston to caliper to fluid, is also a constant.
this sounds like internet hype.

It also sounds like a 9 year old thread

wtf!? why was it on the first page?

sorry
