Are sti calipers the same as evo calipers? If they are it would open up more caliper options.

so i'm thinking that you can do this kit with calipers from the STI, EVO, ISF, Mercedes AMG series, maybe the porsche big reds or yellows, jaguar R series cars, and i'm sure theres others i cant think of right now if i'm right in that brembo has a standard bolt up for all their OEM equipment, than my discovering this with the evo brakes has opened a hell of a lot of doors in brake upgrades yessss i feel like a trend setter :) haha |
ok update on the rears...they arent bolt up like the front
the rear will need a larger diameter rotor, i'm guestimating at 15-20mm larger and you will need to make a bracket, but its an extremely simple bracket to make and you can do it in your garage at home |
ok heres the start of the write up on the front build
the modifications needed to be made are as follows: Taking care of the bolt issue, theres 2 ways to do it: method 1: you will need to retap the threads into the EVO caliper to M12-1.25 then drill the threads out of the FD caliper mounting holes then bolt it up with the stock FD bolt Method 2: you will need to buy the EVO's OEM caliper mounting bolts then drill out the threads of the FD's caliper mounting holes and then bolt it all up with the EVO's bolts ***i dont know if the evo bolts will tie down with no play in the FD's mounting holes*** the next Mod you will need to do is cut the flaps on the dust shield behind the rotors the ones that go over the top and the bottom of the rotor simply get a grinder or even a dremel and cut the flaps clean off, then the 2 edges that are left over on the caliper side will need to be shaved off too to keep them from hitting the caliper once you're done with those 2 Mods, simply bolt everything up with the g37s rotor screw the brake line into the back of the caliper slide in the brake pads and clip everything up...I'll be using Hawk HPS pads bleed the brakes...I recommend ATE SuperBlue or RBF 600 brake fluid or ELF Frelub 650 nows the last thing you will have to take into account once you've put your whole set up together...wheel fitment i will have to run a 5mm spacer to clear the caliper...this will be different depending on what wheels you have so once you have everything together...throw the wheels on and see whats up if you guys have any questions of details on certain things, go ahead and ask away...i'm waiting for the brake pads and fluid to arrive so once they do i can put everything together |
what wheels do you have?

Sounds killer
Where did you buy the front and rear calipers? Are they red Brembos? I'm curious to hear your road test review on the fronts. Good luck.
|
i just started searching ebay, craigslist, and amazon...
i finnally decided on a set that i found on ebay, lucky enough the guy was local so i checked em out and picked up right there for $500 bucks |
So is it possible to get a set of 355 rotors that doesnt require the tapping / modification?
|
0_0 this is relative to my interests, crazy cool shit!!!

the rotors from the G37s are 355mm and have the same bolt pattern as the FD |
What about boring out the center of the rotor? does the center bore not need to be changed with the g37? what about the rotor offset as well? Wont you need a wheel spacer to clear the rotor? What about moving the cross over tube to the correct location (they are upside down now). There are even more issues with this that I wont list now but I know this because I bought a set of Evo calipers to do this exact same thing. There ARE many more complex problems that you need to solve... you cant just drill the steering knuckle out and bolt them on ;)
Also how are you going to fix the brake bias you are introducing? This is not a simple install, and is the reason I sold off my calipers and modified rotors. |

Im more concerned about the nearly 30lb rotor. I thought he was exaggerating weight, nope looked it up ,nearly 30lbs. I applaud anyone making an effort to improve things and innovate solutions for our cars, but I'm not sure how good I feel about hanging all that un-sprung weight up front.

can u measure the overall diameter of the caliper and rotor so we can see if it will fit our cars(wheel setups)? and finished pics would be great! also, is that that rotor weight just because they are cheap ebay rotors or is that how much they all weigh?

Nice find, thanks for posting!

i dont think it will make a difference and if i'm wrong please correct me..but i dont think moving that tube is necessary |

but what i'm doing is retaping the mounting holes of the evo calipers to M12-1.25...so that i can get get a fully threaded bolt and run it through the FD mounting hole and into the evo's mounting hole |

i'm gona install the fronts first to see how it feels...then once i'm ready i'll install the rear once i have the rears on i'll decide whether i need to upgrade to a 929 master with a willwood brake bias contoller or not i really cant answer this question properly till i have everything installed so please excuse my lack of answers, i'm just waiting for the pads to arrive so i bolt up and bleed everything to see what the out come is |

i'm pretty sure AP racing makes a 2 piece rotor thats gota be at least 2 or 3 pound lighter than these, and i'm pretty sure racing brake and stoptech will all have their 2 piece rotors soon too for the G37 so the unsprung weight issue has its solutions, the only reason i havent bought new rotors is cus i already have these so i figured i might as well just do the kit and fix that issue later on |

i'm gona have at least like 30 or 40 pics of the build in an album that i'll post the link to so you guys can see everything every step of the way i'm pretty sure that its cus they are cheapy ebay rotors...i know that there are 2 piece oem replacement rotors from stoptech, ap racing, etc... |
please keep asking questions and raising concerns like this guys...i wana try and weed out all possible issues with this cus if we can get this to work flawlessly its a hell of a break through
i mean a front Brembo BBK for less than 800 or 900 bucks is not bad at all and a full Brembo BBK front and rear for less than like 1500 bucks... |
I know racingbrake already offers a 2-piece aluminum rotor for the G37s, at least they list it on their website. Problem is, is that they are like $450 each. So after you pay about $900 for rotors, $500-1000 for calipers, and then still have to modify things to get them to fit, the bolt on BBKs that are already offered look like a lot better solution. Again, not trying to knock what you are trying to do, just pointing this out.

thats the major thing for me too...i'm going to get lighter rotors eventually, just using these for now
