Well I m glad you took my advice and went with the pad size I suggested to you. You have now realized why our car is such a pain to deal with. Size constraints. This is the main reason there has never been a strong aftermarket in the brake department for our car. Any decent super sized caliper would require far too low an offset wheel to be acceptable.

As much as i agree with your choice of pad size, I have to disagree with you on your choice of caliper. You have chosen an archaic piece that is even less stable than what you are currenly using. You are giving up a forged caliper in turn for a billet piece which is far less rigid. Ironically, both Wilwood and The Brake Man make the EXACT SAME caliper you are using except the fact that it is forged and will not flex like the billet piece will.

Doc, It wasn't your advice I followed. If I had I'd be sporting around a new Wilwood setup. And, quite possibly no better off than I am right now. As you mention its the space constraints that dictate the size of the caliper and pad selected. The Wilwood caliper is simply too wide when used with a 1.25" thick rotor.
The caliper flex will be much less of an issue for me than it is now, as the hydraulic pressure required will be reduced significantly by the use of larger pads and larger rotors.

 

Hey Dave,
Instead of increasing mass/surface area, have you considered going with a material that has a higher heat capacity--such as carbon?

 

Nobody,

If i'm not mistaken Carbon and rotors made from carbon have less heat "Capacity", what they do have though is an ability to tolerate much higher temps. I could easily be wrong on this. Part of why i think this to be true is that Carbon rotors operate at much higher temps than standard rotors indicating to me less ability to soak up heat. I have also read that this higher operating temp causes all kinds of problems and corrosponding design issues for calipers that work with carbon rotors.

 

Dave, perhaps I missed it but I don't think I did, you make no mention of weight. With your design how much weight are you creating/saving compared to stock or an aftermarket kit. Another question I'd like to toss out, what are the brake differences you are getting now with the Pinnacle front/stock rear setup, and what type of improvements do you expect wit hyuor design. Finally, one other aspect to your design which Brembo, Porsche and Mercedes have been focusing on, temperatures generated with a larger caliper, rotor setup. They created ceramic rotors but the benefits have not been proven yet... goodluck with the project!

 

wantone,

As you might gather from reading the above posts my intent is to increase the weight of the system I currently have. I don't know nor have I estimated what the ultimate weight of the system will be, could be more or less than stock. I will however weight the setup when I get all the parts finalized and in hand.

The differences between my current setup and that I have planned are as follows...
Rotor weight increased
Rotor diameter increased
Rotor thickness increased
Rotor cooling surface area increased
brake pad volume increased
brake pad surface area increased
brake pad thickness increased

All this to achieve the primary goal of better handling of a high heat load.

Ceramic rotors just as carbon rotors are big bucks and this is meant to be a low cost solution to my problems.

 

I cleaned this thread up.

If brake vendors want to argue about who's bling is better, please do it somewhere else. This is DAVES thread.

It is about Dave's Brake System that he's designing for free and sharing it with all of us.

Not why the crappy system -you are- selling is better than the other guys.

 

Hmmmm sounds like I missed something!

 

Very little.
