The 4 pots should be more than enuf with track pads and proper ducting.
I run the 4 pot 13" AP's with Ferodo DS3000's and no ducting. I have no fade problems whatsoever. I do run '99 RZ rear brake setup as well with generic pads.
I haven't had it at Laguna Seca which is hard on brakes yet.... but I imagine it will do well there also.
Brakes are $$$$.

Number if pistons in the brake caliper does not necessarily mean better performance.
Pad area is what directly affects brake performance.
The multi piston brake caliper is just for better pad wear.
...or owners who like to brag about it.

pad area is very important but clamping power is the reason to use the 6 piston. the 6 piston likely has a greater piston area compared to the 4 piston calipers and hence more clamping power. $2000 extra for 6 piston calipers? how much is the 4 piston "kit"? I should build a kit and start selling these. people are charging outrageous money for a simple setup. the rear is a little more difficult but for $2000 you can have the Wilwood 6 piston setup I use on my race car. This setup has incredible performance and is not terribly expensive to build.

If you want AP calipers, you may as well get them from one of the only direct sources in the US and avoid any middle man rapeage fees. Shops like Corksport would just get them from here and then add on their profit margin.
These guys are very helpful and know their **** in and out.

You want AP calipers only or is the kit the important part? I can search for AP calipers specs. do you have a link for the KVR kit? RX-heven gave some good advice. the "kit" is not terribly hard to put together and only one piece is not right out of the catalog. I think that $2800 for 2 calipers, 2 rotors, and 2 adapters is very expensive. seems like alot of markup to me. My six pot kit that I bought from K2 was only $1200-$1500(I can't remember now). It was good deal ut could be reproduced for less.

all my prices are coming from www.corksport.com under the fc3s category of brakes.
I don't care who makes the calipers/rotors, I just want something that will work extremely well.
I can also get the endless kit for $2229 for 4pot version and $3475 for 6pot. I just need to know if I went with endless say over AP is the AP gona be better or not? I just don't want to waist any money.

I don't know much about Endless but the AP kit, if sized correctly, will be more brake than you could imagine. AP is very high quality with a very rich racing tradition. Some of the domesticly produced calipers would be less expensive and perform great. Earlier in this thread I posted some P/N's for the wilwood parts. If you just want an easy bolt on I would use the AP kit. if you want to save some money and do a little bit of the leg work. go through the wilwood catalog and build yourself a "kit". If I had the time I could build you a wilwood setup, but I just don't have time, sorry.

This goes a lot into how the brakes "feel" when you step on the brake pedal.

ted,
you are correct the relationship between the caliper piston area and the master cylinder diameter determines the effort and travel of the brake pedal. I like the kit you and Paul put together and it works great. with the stock M/C it is a bit to sensitive and the pedal effort required to lock the brakes is very small. this is why I changed to the manual brake setup. that way I could taylor the pedal feel and travel by varying the m/c diameters. Paul or you should offer this kit on a special order basis if possible.

Funny, when we worked out the numbers, it should've been a little on the soft side, but I think the pad compound is on the aggressive side!
I think it's more the pad compound more than anything, but you're running one helluva beast of a racecar!
Yeah, I've been trying to prod Paul into starting production again, but he's just not interested.
I know he's sitting on a bunch of raw parts, and I've expressed interest to clear out his inventory by reselling them under my label...

yea, I can see how he is not to motivated to get into the parts business again. running your own business especially a motorsports related one can take a hard toll on you. If you could find a larger diameter M/C that would work with the OEM booster the pedal effort would increase to a normal level and work with the booster.

99 RZ Brakes?
What about the Mazda factory 99 RZ Brakes?
MazdaMotorsports lists the RZ Rotor at 1.25" thick for around $130 and they show the calipers for approx $370 or so. Might make a good alternative to a Wilwood setup. You might even be able to pick up a stock 3rd gen Master cylinder for a reasonable amount.

The Superlites are ~$200 each.
The problem of making an adapter plate for something ressembling the stock brake caliper is that it needs to be an "S" shaped.
That's not the best design in terms of rigidity.

nice pics. it shows what I have been trying to describe. the same techniques can be used to adapt any calipers. 2 piece rotors are easier to put together but OEM models can work

I know i need one with big bore, i can work with both ABS and non-ABS one (if only difference is with number of outputs) and i would like to know part numbers for both of them
