New D2 brakes on the Z
 

Hey, I just thought I would post up some pictures of my new brakes. They are 380mm 12 pot D2 brakes with 15" rotors. Let me know what you think.

Nice brakes. Do you have all 4 or just the fronts

nice

Yea we put all 4 on. The last picture is of the rear brakes. They are 6 pot and 13" rotors. Hopefully we will have the car up and running soon so we can try them out

pictures really dont do these justice.......they are huge....and these are National Speed Custom colored calipers you cant get the D2s any where else in those colors....they come in the crappy purple otherwise

looks good...don't really know too much about them though.

i'll second that. i saw these today, they are huge. looking forward to the future of this Z!

Yeah really......Kurt your car is going to be bad @ss!!!

and those are 19 inch wheels!!!!!!!!

More pics further out please. Thanx

12 pistons and only 1 pad per side?1?!? Is that what I see?

Those would stop a 10 ton truck!

lookin good!..how much was the total?

Why in the world would you need that much stopping power? I'm guessing you have some crazy engine build?

Can tires even supply you with enough grip to use those things?

Huge

here you go(keep in mind those are 19" RE30's):

yea we're in the process of building a custom twin turbo setup for our 4.2l stroker

Kurt correct me if Im wrong......but the rear is 13" rotors 4 pot. Right?

13" 6 pot

Those fronts are huge....

did you paint the calipers?

i have to pee now. the fronts are GROSS!

the brake makes wheel looks like 16" lol

HBBK
 

What's the weight (lbs) of the front/rear HBBK? Is their enough line pressure or did you have to get a larger brake booster?

Very nice!!!

i would not trust this at 140+mph....

saving $ for some real brakes.... wilwood or stoptech


i say RICE !!!

why do you say this? D2s arent real breaks? They are made the same way that wilwood and stoptechs are....not to mention this product line has a nice R&D department....Safe at 140+Rice.......what is ricey about these brakes?

in china, right ?


can they post this in " about us" page ?

http://www.wilwood.com/Centers/Infor...ages/about.asp

I have the link at home...but I'll post it later - these are a nice bbk alternative. I'll be interested to see how these measure up performance wise. Also, the D2 rep I talked to was very helpfull. They also offer air ride coilover setup that has very flexible dampening controls as well as height adjustment.

IMO D2 is a pretty good average cost/quality company they make good products........

That is a sick brake setup!! What is the weight comparison compared to stock brembo's anyone??

If D2's brakes are anything like their coilovers then run for the hills!

if you don't know something to be factually correct you probably should avoid posting about it

If they are just as good as Stoptechs then lets put them on a ALMS GT1 car and run them at The 12 Hours Of Sebring. That's what Lou Gigliotti does with his Stoptechs.

Do they even make a race compound pad for the D2 caliper? :dunno:

Why are their coilovers shammy ?......not like i ordered them or anything , just curious

Their valving is worthless. No two shocks have matching valving. Their parameters are wildly off. Their adjusment setting are worthless too. One set on the lowest setting and one set on the highest setting might match. But the dampening between the same valve setting on two different shocks seems to be completely unrelated. The chances that their spring rates come close to matching is next to nothing as well. Even companies such as Eibach who are in the spring business can only get their springs to come fairly close to matching in advertised rate.

Ahh....that blows. thanks for the info - their coilovers looked inviting to try out too - not for track purposes but just for street. http://www.d2racingsport.com/air-Pro.htm - esp if your driveway is looks like \/ - like mine.

Here's the link to the brakes...the rep basically said 150 for the powdercoating in any color they had available. http://www.d2racingsport.com/brake.htm

Links fail

I'm pretty sure the links work....

For the street your not going to notice the dampers shortcommings. You will notice the shortcommings on a track with an experienced driver pushing the car to the limits. That's when you're going to notice these inconsistencies in a set of dampers/springs/alignment etc.

For dropping your car for the street and occasional track fun days I say buy whatever is cheapest under $2500. They will all be of the same quality with very few exceptions like Billstein, Koni, and one or two others. The lower end dampers by TEIN, KSport, D2, JIC etc. are all inadequate for the track for competition or or even HPDE if your goal is low lap times and consistency.

As far as the D2 brakes are concerned it seems they are another manufacturer to target the trend of more pistons are better. Well that simply isn't true. The more pistons a caliper has the weaker it becomes and the more flexible it becomes. To compensate for the increase in caliper flex the caliper is built larger and heavier which goes against the goal to reduce unsprung weight.

Stoptech builds 2 different setups for the Z. A 4 piston front and a 2 piston rear, and a 6 piston front and a 4 piston rear. Stoptech will be the first to tell you that the difference between the 2 setups is that the 6/4 combo has biggger pads. Bigger pads won't make you stop any better but they will last longer which is good for endurance racing.

Sooo generally anything more than 6 pistons is a waste. 12 is extreme overkill and is geared towards the bigger is better show crowd.

:icon18:

Not to mention..the more pistons you have...the more your odds increase of one of them failing.....

Ouch. Thread was a 10 now down to a 6 lol they look ok IMO but 12 pistons is a little over kill. I thought 4 was the best all around??

I'm in full agreement w/ you anything more than 6...the pistons become smaller but greater in number, offering no real advantage. These particular brakes as far as I know have been a unknown in the Z community and any additional info is always helpful. As far as height adjustment I believe one is out of luck if they have a dedicated track car. I've heard good things about the Top Secret roberuta cup but the people that I know that have this only street their car and unfortunately it doesn't fit all coilovers. It would be great if there was a track solution for dampening and height adjustment on the fly that was a little less damaging to your wallet like the above mentioned, but who knows...

- and trust me OLDdirty...whether one likes to believe it or not, the majority of Z owners never sees the track but still wants a product that's track ready and is bling at the same time. If there were more people in the Z community that were like this, I wouldn't be receiving PM's every week wanting the track headlight covers I fabricate to be wrapped in CF....So if at every thread you comment on pertaining to the track benefits of a product from seibon and other aero to bbk's I guess we won't know for certain until you try it out and get back to us...;)

Have you been wanting to say this to me?? I understand what you are saying and it is 100% true but I'm kinda don't get why You said that now?? What did I just say to make you think I don't like things that are not functional or track approved?

BTW I cant get the links to work?

:icon6: ^ Thats funny.

Why is it funny?>?

OK...maybe its not. But pointless bashing = teh gay

....

Damb???? On my nutz or what??? lol Tow hook thing is FTW

Maybe you should take your own advise? :dunno: But thanks for reminding me how ghay DD tow hooks are and most wings.

99% of the modifications done to cars is for looks and nothing to do with performance. BBK's that will never see a track. CF body parts with no weight savings over OEM. Big wings with downforce on cars that don't see track speeds to even become effective. Aero kits that have no aero advantages.

Sometimes I wonder if the lightbulb will switch on in some of these peoples brains who mod cars that I added alot of performance to my car and I'd like to see what it will do around a track instead of sitting at a HIN show. Even if it only once. Just use the parts you paid for. Ooooops but then again they may get scratched.

Bottom line .... get out on a track and use these parts for what they were intended for.
