anyone have them besides works2r ?



i'm probably gonna be investing in them soon. any place to get them besides ntech or m2 ?

seth has 6 piston willwoods for his yellow car, those things are ginormous!



mike

well i can get 6piston wilwoods from a friend but he upgraded to 4 piston racing. i can't let him have better brakes than me you know !

Yes... https://www.nopistons.com/forums/pub...IR#>/smile.png



Pedal travel is a little longer - prolly curable w/ the 929 master cylinder upgrade. Braking is better only cuz of the pad upgrade from stock. However, these should be better for fade resistance. Kit is very high quality; however, it was mentioned that the CP5200 calipers are a street caliper still. And any serious track/race usage should consider upgrading the pistons/seals. I forgot the name of the company, perhaps, WorkS2R remembers.



You'll prolly need to upgrade the rears to get the braking balance proper.



Either case, they are really nice. Your alternative could be the kit Dale Black is offering or the M2 house-brand that could be ordered for all 4 wheels + e-brake option.

we'll see. i'm still in the deciding stage

How about I get you some 8 piston calipers off of a new Mercedes SL55 AMG?



Those **********ers have 4 brake pads in each caliper :yum:

whoa.........

I'll tell you what, That car stops faster then any goddamn car I've ever driven. I believe its one of the fastest stopping production cars ever built.



It broke traction at 75 mph when I stomped on the brake pedal.

goddamn! that is ridiculous. way to go MB :bigthumg:

I hear they are coming out with 24 piston brakes next year

In one caliper? Why?



That SL55 has 24 pistons total and stops like a MF, why more?

:eek:

Pics!

more pistons doesnt necessarily equate to better stopping power, I just wanted to point that out.



I used to have Wilwood 6-piston jobs, and I have AP 4-Pistons now.



My current APs stop a whole hell of alot better than the 6-pistons. Its more about friction area, etc.



Its mainly physics, Law I and Law II, just remember that you can only stop things in motion with opposing force or bleeding force https://www.nopistons.com/forums/pub...DIR#>/wink.png

Yeah what he said https://www.nopistons.com/forums/pub...#>/biggrin.png

YOu can only stop as fast as your tires will allow. sticky race tires will make your eyes buldge out of your head, but street tires are just street tires... Bigger brakes only allow you to make repeated stops like this with out fade and give some better modulation. If you go too big you end up carrying around a lot of unneeded un-sprung and weight and extra rotational mass (somthing that someone who drag races does not want...).



my $0.02

Yeah those things are beyond fast. I raced a Cl55 in my fd and it handed my ass to me! They put out like 450hp stock!!

the new ones are supercharged and have 493hp/516tq

we went to the track on saturday. mike avila was there he has the ap kit and his rotors are cracked from the heat !



mike

well the bigger rotor also gives more pad area which equates to more braking surface. https://www.nopistons.com/forums/pub...DIR#>/wink.png

I heard AP is pretty good, are you set on the company Vosko?



Or are you shopping for all companies?

i'm not set on anything. can you get me a good deal from japan ?

4 piston?

6 piston?



Anymore and DAMN you might flip it HAHA

4 piston

cool, give me a few hours. Not much I can do from work

unfortunalty

no problemo



i am a patient man https://www.nopistons.com/forums/pub...#>/biggrin.png

I believe Tar-Ox makes some 10 piston calipers. HPI may also make some 10-pistons. Mark V. used to have 8-piston Brembos with 4 pads each on the front of his FD with 14" rotors. Bux!



EssexParts.com can install SS pistons in the AP CP5200 calipers. I had them upgrade mine and they work fine on the street and should hold up better (not boil the fluid) on the track. All said, it makes for a rather expensive set of brakes, though. Essex can get you some Ferodo DS2500 street pads and DS3000 track pads, too (for both the AP and Wilwood calipers, see below).



I have Wilwood 4-piston calipers on the back. Here's a write-up on that:

http://www.maxcooper.com/rx7/how-to/brakes...rear/index.html



You lose the parking brake with those, but I haven't had to park anywhere steep and it hasn't been a problem for me yet. I just put the car in gear, but it won't hold on a steep hill. Widefoot is working on some new brackets for the Wilwood NDL caliper that will also support a single-spot mechanical caliper for the parking brake. dclin on the forum is investigating 2-piece rotors to use in place of the RZ rotors, and I expect those to be available soon (group buy, probably). The car felt way out of balance with the AP fronts and stock rears, and it feels much better under braking now with the Wilwood rears.



You can install a 929 master cylinder to increase pedal effort (trust me, it still takes much less pressure to slow down than stock) and reduce travel. You'll have to double-flare a few brake lines, but Rob Robinette's site has a good how-to on the install.



My fronts are 2 lbs lighter per side than stock, and the rears are 4-5 lbs lighter per side. Big brakes and less unsprung weight! I am sure the rotational inertia is higher, though, since the rotors are larger in diameter.



For four wheel brakes, look at these options:

- Dale Black's Wilwood fronts w/the Wilwood rear setup I've got

- M2's four wheel setup

- Mazda RZ stuff (great bargain for great brakes!)

- AP fronts / Wilwood rears like mine, but the different brand name on the calipers is a little silly. I think Essex might be able to supply AP calipers for the rear as well, but I didn't want to spring for them after spending so much on the fronts. AP calipers would probably cost at least $600 more (ouch!).

Thanks Max :bigthumg:

Just drove by a G35 coupe with the Brembo brake option from Nissan. Why not put someting together with appropriate discs, custom bracket and calipers from your local Nissan parts counter? They have to have some kind of parking brake setup. The rears look like twin piston, one on each side of the disc.
