I just found this, but was curious if anyone has experience w/ them.

Have't heard of them.. not a lot of info on that page.

What I want to know is how they became "THE PIONEERS OF BRAKING PERFORMANCE"?....

 

KVR has been around for years. They just recently, in the last 5 years, opened a warehouse in FL. The one I always deal with is in Canada...

riri, they're always in the back of car mags selling drilled rotors.

 

I sent them an e-mail requesting information...I'll report back when they get back to me.

At least they're the right color!

 

haha, aint that the damn truth...

 

Look nice. Maybe Senor Hasty has some input.

 

Hell Yeah!

I like the red! lol

Anodized for me please!

You guys with PY might not need this particular color though...

 

Here is the reply that I received from KVR Performance:

I replied with :
Interesting...this means that since it was designed to fit under the stock Honda steel wheel it is actually a smaller caliper than my car comes with from the factory. As the stock caliper just barely fits under the stock 15” rim of the Type-R. Would there be any benefits for me to use this setup, as it looks like it will be a downgrade as opposed to an upgrade. It is indeed a 4 pot caliper as opposed to the stock 2 pot caliper, but it appears that the pad area has been decreased. Any assistance would be helpful, as there are quite a few Type-R owners that are now looking into this system.

I am awaiting another answer...the price looks good, but the product does not look like something that would be an effective upgrade for the Type-R owners.

They give a different part# for the Type R and CRV. I'm assuming that it's a larger caliper for those applications, but it will be interesting to hear their response. Keep us posted.

 

These are interesting......But I have my mind set on Fastbrakes 11.75" 4-pot set-up.

 

DITTO. you can get two 4 pot calipers and two 11.75" rotors for for under what you pay for just two of those calipers. fastbrakes prices=

 

ditto. provided there is substantiated proof that they decrease the stopping distance over stock...

 

There was someone who came into Acura a couple of months back and had some aftermarket 4 pot calipers put on(can't think of the name). However upon inspection by myself, I pointed out to the tech that there was the same if not less pad surface than the stock pads. So doesn't that sound like a phat waste of money for less serface area? Hell they didn't even fit correctly, they had to put like 7 washers in to space out the caliper(minor flaw that could be fixed) So could these 4pots acctually be better?

 

advantage for 4 pots is for better control, modulation, and feel which uses the total surface area of the pad as opposed to the stock single piston (1 pot) caliper set-up on the ITR. The nsx uses 2 pistons (2 pot) set-up.

 

Thankx for the explination vaporsi

 

Here is there last reply:

There you are.

Hmmm.....is that a brake tech speaking or a salesperson? I'm gonna find it hard to believe that less surface/more pots will provide better braking. Maybe I'm clueless, but I'd want some solid proof....and not from the marketing team either!

 

Ok here goes my little explanation...take a piece of paper,.... a BIG piece of paper and out ur hand on it and try to move it across the table(this would be symbolic of a stock brake ad with two pots)...now take a SMALLER piece of paper, put both hands on it and tell me if it isnt harder to drag across(sybolic of smaller pad area with 4 pots)...same goes with brakes..one piston exerts less braking torque than two pistons, even if the brake pad area is bigger. thus, more pots and less brake pad area is still better than more brake pad area and less pots.

 

1st - The stock calliper only has ONE pot! Why on earth do people think they have two?

2nd - This analogy is completely bogus! The total piston area (not the number of pistons) of any calliper is going to indicate the amount of force applied to the break pads for a given pedal travel. If the pad sizes were the same then the total amount of force applied to the pads would be constant between a one and four pot calliper. The two key differences in using a four pot over our push pull single pot design are the following:
- The four pot calliper will provide even pressure (force/area) to both inside and outside braking surfaces on the rotor.
- The four pot calliper will provide even pressure over the surface of each pad.
Both these benefits improve breaking performance by reducing hot spots on the pads and promote even pad wear.

One thing to consider is that in a good design the total piston area for the upgraded calliper should be roughly equal to the area of the stock calliper. Changing this area significantly will adjust the break bias and peddle feel considerably.

okay, im wrong on that one. you got me.

But on this one I believe i said something similar. One hand covers less service area than two right? and two hands(two pots) would provide more pressure of the surface of the pad right? so im not compeltely BOGUS!

 

NO, what you fail to realize is that (and I tried to convey this) if you want to keep the same break bias on the car you will need to install a 4 piston caliper whose pistons have the same TOTAL area as the single piston you are replacing.

In other words each piston has half the surface area! So although you are pushing with more hands, you are now pushing with smaller ones! The total force applied will be the same but it will now be distributed more evenly!

Don't be confused when I say that the pistons are half the area and not 1/4th the area. Apposing pistons in a 4 piston design act as one piston when we are talking about the forces applied. This is because they are pushing against one another. If you can't see this then you will have to try and convince yourself that this is true, because it is!

Regards,

 

Another thing to keep in mind is that even though a caliper may use a smaller pad (in actual surface area) than another, the actual area of the rotor that is swept by the pad is what makes it more effective. For example, on a 13" rotor, the swept area can be less than that of an 11" rotor, but the 13" rotor will still provide more leverage than the 11" rotor.

As for the 4 piston vs 1 piston, if the piston sizes add up to the same surface area, both calipers will have the same clamping force. The advantage of the multipiston caliper is the smaller pistons react much faster to input either from the rotor surface or the brake pedal. They are much easier to modulate at the point of lockup then a single piston.

Putting a 4 piston caliper on the same rotor as a single piston will allow better control of the rotor, but it won't give you any more leverage.

Better braking can be defined a number of ways, stopping faster is just one measure of that. For street cars that usually means stopping or slowing the car quickly enough to avoid hitting something. On the track it means slowing the car from the top speed to speeds needed to negotiate a corner in the shortest amount of time, and do it with the same feel, etc for the length of the race. Sometimes these two criteria are mutually exclusive, most times they overlap.

One of the hardest things to do is design a system that has to do both things well enough to satisfy the majority of the vehicle drivers.
