Hi y'all,
I've been doing some DE's down here at Texas World Speedway and my stock brakes are not enough anymore. Heat is such a big issue down here, it has to be dealt with. I've put a lot of thought into this and came to the conclusions that:
1. the stock calipers are enough
2. need slotted rotors (looking at DBA's 4000 series)
3. SS brake lines
4. better pads (was thinking about starting with Hawk HPS)
5. front brake duct kit
6. upgraded brake fluid (not sure what to get, that is compatible with brake system and clutch)
What are your thoughts on this setup?
thanks,

 

For brake fluid I used the ATE SuperBlue as it it lets you know for sure all of the old fluid is out as you keep bleeding until the fliud comes out blue.

I used the Quantum brake cooling kit and so have others here. See this thread https://mustangforums.com/m_5258855/tm.htm

 

sounds good, thanks.

 

ATE also has TYP200 that is amber color (same fluid as Super Blue, just different color) to help the next time you change the fluid.

I have gone through two sets of HPS pads and they are great step up pads. Much better bite and feel than stock. Low noise and the dust isn't bad on the street. They hold up well on the track when you are starting out and you don't have to change them when you drive on the street.

I went to SS lines last year and am happy I did. Nice solid pedal and piece of mind on the track.

I installed the Quantum Track Kit with their inlet plates this year and I can tell things are much cooler when I get back to the Paddock. I plug them on the street (see the thread Sleeper_08 mentions).

I was talking about rotors to a couple of instructors in the "tack club" and they were saying that newer pads don't create as much "gas" as they used to and slotted rotors are a waste of money. A debatable point I'm sure, but a data point none the less.

 

I've done 16 track days at TWS over the past year and the only brake upgrades I've done are Castrol SRF brake fluid (overkill I know) and Carbotech XP10's on the front and XP8's on the back.

I went Carbotech because I can use the Bobcat pads on the street without changing rotors.

I'm installing the Quantum Motorsports front brake duct kit before the TWS Motorsports Club event on the 26th, not because of brake fade but to extend the life of the calipers, wheel bearings, and tie rod boots. I also read a tip to wrap aluminum A/C vent tape around the tie rod boots to extend the life also. I'll do that while I have the car taken apart.

 

Upgraded stock brakes will work for a season or two. But, it won't be long before you burn them up. Once they start to chatter, you've smoked them. That '07 GT is no light weight.

If you're going to continue this, you really need to consider some real brakes - like Wilwood, Baer, or Brembo. Yes, they're expensive. But when you brake at the 1.5 marker instead of the 3.5, you'll be glad you did it.

My track car weighs about 1/2 a ton less than yours. I burned up stock Mustang brakes so bad the discs were blue. I now have 13" 6 pot Wilwoods. One of the best performance mods I'v done. The car will almost stand on it's nose. It goes from 130 to 70 in about 3 car lengths. Lap after lap.

I appreciate all the info. I'll try the slotted rotors, it's gotta help. I'm melting my stock pads to the rotors now. And the ATE typ200 sounds good, i've seen other people use it with success.

 

If they're getting that hot, you should consider some cooling ducts.

I fabbed some up for my car a couple of weeks ago. Nothing fancy. Bought some 3" hose from Pegasus Automotive. I used wire ties and hose clamps to attach it to a frontframe member and the tie rods. I don't have a fancy plate (yet), so I just aimed it at the center of the rotor.

I was at the track all week end, and it was really hot on Sunday. Air temp was mid to high 90's. Track temp was well over 110* I'd guess. Brakes performed much better. They stayed cooler, never faded, and I couldn't smell them cooking.

I'll try and add some pictures to that gallery above.

 

Bob's ducts are kinda hoakie (sorry)

They're better than nothing for sure, but a spindle mount to direct the air into the hat would be much better. In Bob's case he has 2 piece rotors, so on his car it's probably enough. On our 3500lb pigs that kind of setup isn't going to do the job.

After 2 years with my '06 on track, having been beat on by myself, my driving coach, a few Nationals podium AI drivers, a World Challenge driver, blah blah blah......the stock brakes work just fine. Robin Burnett has been on the podium 2 years in a row at the Nationals in his S197 with stock '05 brakes. I can get a set of Brembo's for a SICK discounted price yet I still choose not to and why? - because 18" R-compounds are F'ing EXPENSIVE - $80 more a piece in a 275w!

It's been said over and over again - ducts, good fluid, braided lines, and good pads will do the job just fine. BBK's might give you longer pad life but more tire budget, so you still lose in the end. Slotted rotors are a waste. They don't help much at all. You might get a little less pad transfer and in the rain some water dispersion, but at $200+ a set when stock takeoffs are $39 it's a waste.

Besides - what's more fun than giggling at the Evo's and STI's you passed when you point at your stock TRW calipers and they have Brembo's all around?

 

No offense taken, you're right. Pretty simple and cheap set up, but it works. After I took the pictures, I moved the hose to the bottom of the tie rod, thatfits a little better. And I used SS hose clamps instead of tie wraps at the ends. 2 days at the track and they're still firmly in place.

Over the winter I plan on making a good set of spindle mounts for a more efficient set up.
