Looking for Big Brake setup
#16

Pardon my ignorance but why are the brake kits so expensive when the retail price of the 6 piston calipers is less than $300 each (the rear calipers which are 4 piston are a bit less) and the disks are also less than $300 each. Surely, two adaptor plates and 4 braided lines cannot be almost $4000 -- and the metal lines do not even appear to be Aeroquip Aerospace (which might cost $50 each). Having said this, I have seen one firm looking for $8000 for the same kit -- the adaptors must be platinum!

if you think it is easy buy the parts and meke the instalation by your self!
It will not work and the companies which developed teh kit must have some money. They do that for living and spent some time for development and testing.
In Geramny you have to get the TUV aprovness that means a lot of money and A lot of testing by the TUV guys.
@ Shank: MOVIT use the same parts as Porsche/ Brembo and it is not after market parts a sother stated somewhere else.
the rotors are twice as expensive as the calipers

Konstantin:
From what I understand, MOVIT uses adapters to make it fit into the porsche. Also, when you use adapters, you are increasing vibration, correct?
MOVIT did used to use same parts as porsche with their logo, but recently they came up with off sizes to set themselves apart from Porsche. Now this is why it requires adapters.
I have the part numbers for the Calipers, Pads, Rotors and metal lines for the GT2 Upgrade Kit - and it comes out to under $2500.00. Why should I get the Kit for $6-8500.00? I dont understand.
Looks like major marketing to me.
Another alternative I have been advised is to use PADGET PS 19 or P 40 pads, with Castrol SRF fluids. What do you think ?
Third alternative is to get the GT3RS brake kit.

Unless you are tracking your car or are just looking to find an excuse to spend more money leave your brakes alone. Get some more aggresive pads and change fluid out and you will be fine.

Greg, I have 4 reasons why I decided to go for bigger and better brakes. However, I will share only one - "I WANT THEM"
Now that we got reasoning aside, perhaps we can get back to topic. Regarding your suggestion about fluids/pads...What about what I aforementioned... Castrol srf and padget p19 or p40 pads? Any experience with those?
How much improvement of stopping distance will the pads and fluids give me?

Pardon me for interrupting. I believe that the ps 40 referred to above might be the P 40 which is a Porsche formulation Pagid pad generally supplied with the 2002 Type 996 Cup Cars. Finally, as to issues relating to Castrol SRF, it, like many other brake fluids is hydroscopic, i.e., it absorbs moisture and with such absorption becomes increasingly less effective. As such, one should regularly check it, particularly when used in moist climates and in moist conditions. In any event, I (and I am not a brake fluid engineer) would probably change it at least every 2000 miles (3218 km) unless your driving and atmospheric conditions suggest a need for more frequent changes. In any event, one should not look at this, in my opinion, the best of the commercially available racing brake fluids, as a way to save money, i.e., best performance comes at a price. Lastly, the issue of changing brake components may not be as simple as it might appear. Your car may be thought of as a complete system, integrally engineered. For example, your suspension is designed with, among other things in mind, the weight, positioning and effectiveness of your original equipment braking setup. In turn, there are many considerations (and calculations), including, but not by any means limited to, the overall and proportional weight of the vehicle, horsepower and torque, aerodynamics, the size of the master cylinder, proportioning valves, brake pedal ratio, ABS design, etc., etc. that are integral to the design and optimalization of your original braking system. When you change the baseline by the inclusion of larger (or smaller) calipers (generally requiring larger and, in turn, heavier pads), rotors, etc., the need might arise, assuming the desire for continued optimalization (indeed, in some instances, for effectiveness at least equal to that before the change), for changes in other areas of your vehicle. Additionally, the massive brake kits generally add considerable amounts of unsprung and, to a certain extent, rotating weight which, itself, will affect acceleration, deceleration and general suspension performance. In short, buying big brake kits, while "cool" and possibly leading to shorter stopping distances, less fade, etc., will also result in certain negative consequences and, unless done carefully, might result in issues more serious than those merely caused by additional weight.

of course they make money fromthat but tehy also spent money to test them and to get teh aprovness. only one test at the Geramny TUV cost $10000.
you always need adapter or other mods for this set up.
Porsche it self ofers also án upgrade for the 996 TT. Maybe you wnat to take a look at this first?
Other wis ethe SRF and the race pads are the best but it works better only at higher temps. At low temps they are the same and tehy are noisy.
if you brake many times from higher speeds then it is a very nice upgrade.
i think just a better fluid and more agresive pads like the keramic from Pagid should be ok but I understand. The 6 pots calipers looks great;-)
I wouldn't go to the 380 mm front. Just to heavy and you do not need them on the street and probably not even on the track.

FYI - in the U.S. the six piston yellow Porsche calipers are exactly $267.70 (283.67 EURO) each and the corresponding Porsche rotors are $269.80 (285.88 EURO) each -- and that is at full retail -- racers usually get an additional discount. Rotors are in stock in the U.S., calipers are on back order.

Shank-
Brembo GTR kit.
Here is a solution that tested and found to work better than expected. It is less fad resisitant, has better pedal feel and is 30.2 lbs. lighter than stock. .
Email me if you would like more info.

Konstantin, Agree, forget bigger brakes and go after cooling. ONLY after you are having an overheating/fade issue should you consider bigger brakes. Now, if it's just for bling, knock yourself out but be willing to accept poorer performance.
Robert Linton: Good as always. This is the best web source I know of regarding brakes and the exact issue you wisely bring up.

The GT-R brakes look interesting. Mike, have you looked at the volumes/piston area/pressure curves, etc. to see how well it matches our tt ABS?

Just in case people miss my question:
Where are you guys getting these low OEM 6-piston caliper and rotor prices from???
How much for stock TT calipers, rotors and pads?
Any part numbers? I was offered a used set of TT brakes (everything included) for $1700 but if I can get it cheaper new that would be MUCH better...Please do let me know
TIA
