So not sure if anyone here has heard of R1 Concepts Inc. (Google or Facebook them) but they have developed some new kits for the X. Since people were having issues with brake squeal and dust I wasn't sure what to go with. With the power I'm pushing I know I needed to do something just wasn't sure of who to go with.

A friend of mine runs their rotors on his BMW and likes the look and feel and I know Stop Tech makes good products so I opted for the full kit.
It was right around $900 shipped total and that includes;

Front and rear rotors; $600
Stop tech brake pads; $140
Stop Tech SS lines; $160

Plus they have a ton of hot models to drool over ; http://www.r1concepts.com/gallery/main.php?g2_itemId=29

They sent pretty simplistic brake in instructions and once I followed those and put a few miles on my car now feels a bit tighter on the braking. Still no noise and minimal dust really. I'll add more as I go and try these out for racing :dancebanana:

That's a 1-piece, right? how long have you had them? Would be interested in hearing how they hold up after a few track days. The price is right if they can take some abuse.

I've been running 2-piece brakeman procast rotors for 3 years now. Over a dozen track days + 30k miles of DD and they're still good as new. Running them with the Brakeman caliper kit and a combo of their street and track compound pads. I got the full kit for about a little more than you paid plus my OEM brembos. Steal of the century

I just got the StopTech Street Performance pads too.

 

[Murlo26]

I'll have to look into those pads. I am guessing I will need brakes this year, almost 30k and still on the stock shit.

30k seems to be the range where the stock pads are due for replacement. I'm at about 31k, I think Armando was somewhere in the 30-35k range, etc.

yea even shane was commenting last time he had my car this fall that the brakes were sucking. I think they are due for a full overhaul.

 

[Kracka]

Pads & fluid, + getting the rotors turned, for my car this weekend...or maybe next, we'll see.

 

[Demon X]

NIce, I buying rotors this summer

 

[tlsole]

Looks good! 33k here, and my brakes are done. Just ordered me a set of slotted rotors and will be running either hawk hps pads or ceramics, cant decide, im leaning towards hps since its basically more of a daily car for me, with some sprinted runs (lmk what you think). btw, stainless lines arent NEEDED right? Cant wait, i hate brake dust! :duh:

 

[cowtown_cowboy]

lol you linked the models as opposed to the rotors.

nice set up btw i went stoptech too. i'm wondering how this kit you put together compares to the map stage 2 kit with RotorPros discs.

i have 60k miles on my stock rotors and they're still good. this is my daily.

This set up will be a bit higher quality with StopTech brakes and SS lines, plus the R1 rotors are a slotted set up and probably a bit better material.

 

[DRIV4K16]

whats the weight on these rotors?

 

[ak47m203]

I know why Hollywood liked them.....Amy,Alex,Sasha,Lisa,Linda and Trucee was able to convinced you Holly.

why are slotted rotors better? just aesthetics? i always hear people cite the theory of removing gasses released by heated pads, but the pad tech which that applied to died when asbestos pads were done away with. modern pads don't gas. Slotting reduces the mass and surface area of the rotor, which reduces its ability to absorb heat and apply friction. I'm convinced it's just aesthetic, but I'd like to hear your stance Will they be offered as blanks?

Any word on what material will be used? Probably 400-series stainless or aluminum? Please not iron! Is it a cast or machined from billet? How has it been heat-treated? What about coatings?

Regarding the quality, do you have any info on the if they'll be using cooling fins in the ribbing? Even if cast, have the fin edges been machined or hand-touched in anyway way to improve cooling? Once my procast rotors go, I'm thinking of splurging for a set of hurricanes up front:

 

[evodad424]

matbe someone can make a How to for the SS brake lines. Never did one, Im sure i can figure it out but I do like to see it before I attempt it.

 

[sstevojr]

I was under the impression that slotted rotors allow for re-surfacing to limit glazing in track conditions?

 

[blk-majik]

glazing is caused by the pads heating up beyond their limits. pads glaze, not rotors. I guess you could argue that reducing surface area in contact with the pad reduces friction, which reduces heat, and thus glazing... but at the cost of stopping power. well that kind of defeats the purpose

Rotors act as a heat sink and work to remove heat from the pads, which fights glazing. A heat sink's ability to absorb heat is determined by it's mass. Slotting removes mass, thus removes ability to absorb heat, thus makes the pads more prone to glazing. Heat dissipation is improved through designing finned ribs to pull air through the rotor core, not from slots on the outside surface.

dunno what you mean by resurfacing limiting glazing. can you explain?

 

[trick3d]

^Truth. blkmjk any idea what the girodisc 1 pieces are made of? I didnt see it listed on their site.

 

[blk-majik]

Pretty sure it's cast iron. That's what they use for the rotor portion of the 2 piece. Most rotors are cast iron. Steel rotors are hard to make, but they're much lighter and much stronger. However, steel doesn't deal with heat as well as iron, so they're more prone to warping if not cooled properly. But, if machined well, they can improve cooling significantly, so much so that the cooling benefits outweigh the heat tolerance issues.

The pic i posted above is the Brakeman Hurricane rotor. It's a machined steel rotor with vents designed to maximize airflow, and cooling fins build into the vents to get the most heat out of the rotor. Instead of machining from 1 piece of steel billet, they use layers of steel where the outer layer has the most friction, and the inner layers can absorb more heat. It's the best of all worlds.

They have a patent on the tech. It's a cool read http://www.freepatentsonline.com/5626211.pdf
