heheeh, well... my biz partner and I had a good year, so i have some $$ to spend on the track car... thus all the new track car toys ;-)
you may be jelous of the car toys, but i bet you would not be jelous of the 60-70 hours of work per week, working every weekend, and the very little sleep ;-)

Damian - and anyone else who's looking at the Porsche brakes
There are differences in the Big Red kits that Porsche puts on the cars so just because the caliper says Porsche on it and is Red doesn't make it the real Big Reds. My track car is a Porsche, and I recently upgraded to Big Blacks after my wallet couldn't afford Big Reds, so I have been doing some homework on them.
The best I can tell, the Boxster S "Big Reds" are the standard 996 brakes painted red, 318x28mm rotor in front with a 300x24 in the back. The 996 Turbo big Reds are 330x34 and 330 x 28 rotors.
I just bought the Pettit Racing Big Brake kit for the car after thinking about a Big Red kit. I haven't had the car out yet to see a big change.
The other thing that I wanted to ask was if you're using some kind of proportioning valve because of the difference in size of the pistons. I am still not sure if I will need to fit on to my car.
Hope this helps as I see a lot of Big Red calipers for sale, and they are off the Boxster S and not the 996

hi pincusa,
I am a little confused on your data, but i can tell you this, my kit used to use the oem rotors for the 993 turbo and they are 322x32. I dunno anything on the data your reffering to.
the 996 turbo calipers are not the same and i dont even think they are supposed to be called 'big reds'.... some people get confused and call them big reds, but to my understanding the only true 'Big Reds' were the 993 turbo calipers....although the later years did have 'bigger' and 'red' calipers.
>>The other thing that I wanted to ask was if you're using some kind of proportioning valve because of the difference in size of the pistons.
no, becasue the rears are upgraded RS/RZ model calipers/rotors, so the balalnce stayed pretty good, however i just removed the abs (and with it goes teh stock prop valve) so i will be adding a prop valve to adjust it.

I saw this car before he bought it at Laguna Seca. The brakes work well. The driver was braking at the same point or later than the GT2 Porsches that were there.
The first time I went to Laguna Seca I had stock brakes with racing pads and the brakes died halfway through the day. I now have ducted 13" rotors with Wilwood 6 pistons caliper up front and RZ brakes in the rear. It all fits under the stock rims. I have been to Laguna Seca twice with them so far and really like them.

Just a thought - I know some of the big brake kits don't use it, but you might want to consider safety-wiring those nuts. If these are typical lock-nuts with nylon inserts, the nylon is probably going to melt at the temps they are going to see there.

no they are not, as i tried to explain above post, but did a poor job:
>>and the nuts and 'locking' style here the end of the nut is warped a bit.
in other words, the nut is deformed a bit so that once you 'forcefully' thread it on all the way it will not un-thread very easily :-)
that is why my pics show them only threaded to the ends, and not into the deformed part of the nut yet, i did not want the thread them fully yet until im ready to mount them.
this harware/hats/rotors come from a company that does brake stuff for race cars all day/night long, so they know the dealio ;-)

some pics i took of the rotors and calipers that are now big 'yellows' instead of big reds :-)
this was with Andy's (gooroo on the forum) new aquired ssr wheel on as a test fit to see if he could run the same brake setup:
ahh what great color combos:

Is it just me or is your brake ducting coming in from the wrong direction? Or did you just disconnect the hose when working on the car and flop it over?
Great looking brake setup.
Now just don't let those Hawk Blues (I assume that's the pad you have there) tear apart those nice new rotors.
EDIT: Ok I see the brake ducting in your pics of the radiator duct in the other thread. Questions answered!

Wow, Those calipers look almost identical to Stop Techs, which use a Porsche pad... except that ST put a bridge piece between the two indentations at the top and bottom of the pad opening, and mounted the retainer, which is similarly shaped, to the bridge.
The manual says that, depending on the piston sizes, they are a direct replacement for F40 or F50 Brembos (who builds Porsches calipers if i'm not mistaken) as well.

im trying a new airflow idea, get air fromt he back of the engine bay and feed it to the brake ducts, cool huh :-) (hehehe)
hahah, your right, i flopped them over the other way to work on the front, they go to that openign below the oil cooler, you can see it int he back of the pic above.
..and yep those are hawk blues, and yeah, they do eat rotors, and anything else that their dust contact LOL they are nasty, but i do like how they perform, althoguh i do like some of the other pads, the blues are affordable for me, the other pads i like (some pfc ones, et) are much more $$ and with the amount of events i do I can't afford them.

this is how some of the newer porshce calipers are too, so it its a good posibillity that brembo makes them all :-)
