i have to pee now. the fronts are GROSS!

 

the brake makes wheel looks like 16" lol

 

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?

 

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.
