~TLC Brake Upgrade / Replacement Group buy

In the coming days prices for the the brakes will be posted, in the mean time, we can not get familiar with what is offered by our partner Mr. Swain and KVR.

Right off the bat it should be known that KVR is a Canadian Based Brakes Solutions provider. They only carry first line brake products, so you wont get Performance in one catagory and EL Cheapo stuff in another.

Second thing to note, that KVR taps some of the biggest names in the industry to either make their stuff or compliment their own packages. So there should be no doubt on their commitment to quality.

The group buy will happen in 3 segments, one of which is still in the ratification process with the Gold Alliance of Dealers.

1) You will have the ability to make an order, get a great discount and have it delivered straight to your door.

2) You can combine an order with the wolf pack (group buy) in attempt to keep prices of shipping to a minimum. Everything is shipped via UPS, and to my knowledge they are moving within Canada, so there are no broker or duty charges to worry about

3) Some or all Brake upgrades might find their way to the dealership, the cost may be more, but if dealers decide to take stock in them, you will have a open source for grabbing them from a close by dealership or just going in and getting the brake overhaul. Secondly you can bring your brakes that you have already purchased in a group buy and have them installed by your dealership without worry of paying more. These brakes fit OEM spec and require no extra work.

We are in talks again, with the dealerships to see if there can be a brake special so that installation can be further discounted... the dealerships have already promised us a great discount already, so anything further they can pull, would be great. Again all that is still in talks. So please dont bug the dealership with requests like this. Please speak to the dealership club reps, Absolute = Scarb. Rubberduckey = Maple Me for Dixie



The brake stuff. There will be three items we will have access to

Disks/Rotors
Pads
Big brake Kits

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~`

1) Rotors will come in different flavors, 2 piece, or single piece, different colors, different coatings of the disk part itself, and different designs, cross drilled, slotted and the new J slot design. Here is a quick blurb on each.

a) J Hook


For decades now racers and performance driving enthusiasts have selected slotted discs when upgrading brake performance. Now, our innovative J Hook slotting offers the first new, significant improvement to that track-tested design in four key areas of performance:



Greater Initial Bite: Allows for a faster reaction at high or low speeds, when compared to std slotting
Superior Pad Cleaning: Brake pads are much less susceptible to glazing with Hook slotting
Faster Pad Release: The innovative J-Hook machining allows the pad to release more effectively than standard slotting, minimizing brake drag
Reduced Thickness Variation: J Hook discs are less susceptible to brake pad build up, which normally causes runout
Whether you are a racer looking for that competitive edge or an automotive enthusiast looking to upgrade from your original factory gear, check out the latest from the Leader in Advanced Braking Technology, KVR Performance.

b) Super Sport 2pc Discs


KVR Performance has answered your demand for a superior brake disc with a product so advanced that it not only stops better, it also makes horsepower at the drive axle! Super Sport 2pc Discs from KVR Performance are precisely crafted from superior materials and are engineered to look as good as they perform.

All Super Sport 2pc Discs are assembled by hand to exacting tollerances and are verified for:

Surface Finish: 60 ~ 80 rms
Run-Out: ± 0.002"
Balance: ± 0.7kg/cm

The perfect choice for drivers who demand the best for street, the drag strip or the road course! Customize your selection by selecting the disc surface and finish and the hat color to suit your driving style and budget.


options include

Disc Surface: Plain, Cross Drilled, Gas Slotted
Finish: Cadmium Plating Standard; Dacromet and Cyro Plating
also available.
Hat Color: Black, Red, Blue, Gold or Silver

Product Highlights


Two Piece Construction - Reduced Mass Increases Horespower & Torque


Heavy Duty Axially Vaned - Left and Right Rotors supplied for Max Performance


NAS Hardware Secures Hat & Disc - Titanium Hardware Available


CNC Billit Aluminum Mounting Hats with KVR Velocity Channels - machined into the hat to direct air to the outboard face of disc, Velocity Channels equalize inboard and outboard temperatures, increase the stregnth of the flange and reduce mass. Black, Red, Blue, Gold and Silver (not shown) plating available.


Thermal Cycling Indicators - Thermal paint is applied to the rotor and serves as a visual gauge. Two paints are applied: Green changes at 430 degrees Centigrade - to show that the disc is absorbing heat. Red changes at 610 degrees - telling engineers that the system requires more cooling, or telling a driver to back off to let the brakes cool.


c) OE Replacement Parts
KVR Performance offers OE Replacement 1pc CNC Machined Discs with a variety of surface and plating options. And KVR Carbon Fiber Brake Pads are a low-dusting, affordable upgrade for Street, Strip or Track.

KVR Performance
CNC Machined
1pc Discs By using superior materials and state of the art manufacturing methods, one-piece discs from KVR Performance provide a dramatic decrease in stopping distance. All Discs are CNC Machined for Maximum Precision, and are designed for direct, bolt-in replacement of your vehicle's Original Equipment permitting easy installation!


All KVR 1pc Discs are available with your choice of surface treatment: Plain, Cross-Drilled or Slotted. Machine patterns of discs vary due to the design of disc and the application - there is not one pattern that works better than another.


Plain: Retains the appearance of the OE Factory Disc while enhancing performance.


Cross-Drilled: KVR uses a specially designed end mill to bore the holes into the rotors. This process is more acurate than drilling, and has proven to be the best way for limiting stress relief. Cross-Drilled rotors run cooler, reducing brake fade and warpage while increasing rotor life. You'll enjoy shorter stopping distances, esepcially in wet weather, whit a set of Cross-Drilled.


Slotted: All slots on KVR one-piece discs are CNC machined for maximum precision. The entire slot is located within the disc annalus (braking surface) to reduce the chance of thermal shock and eliminate stress points. Slots channel gasses produced under hard braking by your friction materials away from the braking surface for enhanced initial bite, giving you a competitive edge on the track or the street with their tough, performance look.


Optional Cadmium Plating: You can further enhance your brake disc upgrade by choosing a Custom Cadmium Plated finish, in your choice of Silver, Gold or Black. Protect your investment from rust and add a healthy dose of style to your ride at the same time!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

2) Carbon Fiber
Brake Pads





Click to enlarge KVR Performance delivers the Superior Stopping Power of Carbon Fibre Pads at prices Affordable for Everyday Use! You'll get superior performance from our semi-metallic carbon fibre pads; their metalurgical formulation exceeds all O.E.M. standards, creating a quiet running brake pad that performs with minimal increase in dusting. The perfect choice for Street Performance vehicles that may see occassional on-track action.

Designed to compliment our 1pc O.E. Replacement Discs, they work great with plain, drilled or gas slotted rotors.

KVR Performace Carbon Fibre Pads - Your Best Braking Value!
• Shorter Stopping Distance
• Less Brake Fade
• Less Rotor Wear
• Kevlar Insulated for Superior Heat Transfer
• Integrally Molded for Long Life
• High Density Compound Minimizes Dusting

~~~~~~~~~~~~~~~~~~~
3) Big Brake Upgrades

More info to come shortly...



~~~~~~~~~~~~~~~~~~~~~~~~~~~

So in the mean time everyone should be thinking hard about what options appeal most to them. Cost will not jump around frome style to style. Unless of course you go the big brake upgrade way.

I will update this thread as soon as I know what is going on with the pricing, A vote will get started to gauge what people want more.

For the purpose of te buy, evo I think it would be a good idea to do a few dyno runs to compare the gain of hp and tq from the 2 piece. Also it would be nice to get a small road course to compare braking distances from before and after to ensure that this will benefit the owners. Multiple "100-0" "60-0" an say "30-0" braking

on a side note will the new rotors affect the abs an howthe mechanism works

Very good. A+ for this Group buy.
What time frame are you looking for this GB? Does the super sport come with Cadmium plating?

Very interested in Slotted / drilled super sport or OE replacement discs and CF brake pads.

this is something that has already been proven. how much depends on alot of factorsm the budge for such a test would run up to about 1500 to 2000o dollars to do properly. and again since our ecu has short term fuel trim issues it would require a usa spec lancer.

if anyone wants to donate, i would conduct such a test.

the best way to test this is multiple runs on the drag strip.

for sure the benefits will show there

brake upgrade would not be affected by the ECU learning curve

its a simple weight reduction engine puts out same power, but less rotational mass to the wheels cause it to reach speeds faster, it wouldnt change what the ECU has to do and is already doing

load goes into the calc of short term and long term fuel trim. because the reducion of losd doesnt show up into the long term fuel trim until much later on.

there should be the same issue because i talked to workd about it in regards to winter tire vs summer changes...

awaiting prices. TLC racing guys, might be a good time to upgrade to some good rotors and grab a set of track specific pads later.
If anyone needs these installed, case of beer works wonders.

Okay, Here we go.

Laksman, as far as 'power gains' Here's a calc for an STi.

For an 8 pound change in wheel mass concentrated in the outer rim at an 18" diameter (total of 32 pounds for 4 wheels), you're looking at about a 1.34% gain in effective power to the ground. 0.44% comes from the inertia reduction (the rotating part), and 0.90% comes from the reduction in weight of the car (the straight-line part).

If you were to reduce the same amount of weight from the rotors, the gains would be smaller since the weight would be concentrated at a lesser radius. You could scale the rotational gains by (d/D)^2, where d is the diameter of the rotor and D is the diameter of the wheel.

Assuming 14" rotors and and an 18" wheel, this would give 0.44% * (14/18)^2 + 0.90% = 1.16%, or about 2.6 whp on an '08 STi.

In case you're interested in the actual power increase calculation from inertia reduction of a wheel:

dP = (d_rim / d_tire)^2 * 4 * dm_rim / Mv
where
d_rim = diameter of the rim (18" on '08 STi)
d_tire = diameter of the tire (25.72" on '08 STi)
dm_rim = change in weight of the rim (~8 lbs for '08 STi non-BBS to BBS)
Mv = mass of vehicle (~3550 lb for '08 STi with driver)
Verdict. Light weight rotors is not a very good way to 'free up' power. You're better off getting a light weight crank pully or underdrive pullies.

-----

As far as Stopping distances, i would say the OEM vs "upgraded Rotors" will yield less then 3' in a 100-0 stop.

Slotted rotors helps prevents brake fade from back to back to back hard stops, ie, road courses, as it prevents the pads from glazing over.
