Brembo stopperz
 

So I figured I would share my latest project with the group. Ever since I installed 18 inch wheels, my stock brakes have bugged me. At first my car had FWD calipers and rotors so I upgraded to the AWD calipers and rotors

Still, the large wheel left a ton of area around the rotor that drove me crazy, didn't look proportional. So I started looking for other options for the future.

Baer brakes make a kit for the car, but still a dual piston with a pad not much bigger than the my AWD pads and a slightly larger rotor. StopTech makes a kit also, and it's nice, but the price isn't. Then I thought about 3000GT VR4 4 pot calipers but there wasn't a rotor that would clear my wheel. Thought about Evo calipers, but again, price and the rotor would hit my wheel.

I did some research as to how people were getting VR4 calipers to fit. Some were experimenting with rotors off of Audis and other cars. I went to the parts store where they let me look through their parts book. They listed rotors, the diameters, bolt patterns and offsets. I found a rotor that was 14 inches with a huge offset and a 5x115mm bolt pattern (mine is 5x114.3) for 1/2 inch studs (mine are 12mm)

Bought that and test fit it to my car. The VR4 calipers cleared with a ton of room to go but I did have to turn some un-needed material off of the back of the rotor so it wouldn't hit the knuckle.

At work one day I was looking at the calipers on the Vipers. They are a Brembo 4 pot caliper and is the same casting as Evo's, STi's, CTS-V's, etc. I decided to test fit one of the those, IT CLEARED! I was able to get a used set of calipers through my work so I just had to slap some new seals in them and paint em.

Well bigger calipers = more fluid that needs to be pushed. I did some research and the 3000GT brake master cylinder is the same bore as the Vipers. Did some more research and the 3000GT master will bolt up to my booster. Just need to modify some of the brake line routing.

So here is where I am at:

Re: Brembo stopperz
 

Here you can see that the center bore of the rotor is larger than the step on the wheel bearing. Also the holes for the studs are larger than the studs so the rotor is not concentric. To fix this I used a hub-centric centering ring to center the rotor.

Here you see the back side of the caliper and rotor. This is where I need to make a mounting bracket

So I bought some solid aluminum block to machine on the bridgeport at work. Here you see one bracket I started notching for the knuckle

Here is a bracket fitted in place. You can see the lines I made for material I still have to remove.

Here is a small taste of what they looked like when I was mocking it up except here I have a friends Volks on there which is a 19.

Re: Brembo stopperz
 

I finished the bracket for one side. Took a little longer than I anticipated (about 10 hrs) but the quality is what I hoped for. I expect the other side to go faster since I have a game plan now.

Here is the wood blocks I machined to keep the caliper centered on the rotor. These are thicker than the pad so I can push the pistons all the way in.

Looks like it will be only 18's from here on out, not much clearance in there.

Re: Brembo stopperz
 

Built the other bracket, went much better. Only had about 4 hours into this one now that I had a game plan.

Just gotta rebuild and paint the calipers, slot the rotors (I still need to order another one) and install everything.

Re: Brembo stopperz
 

Buy your friends TE37's.

Re: Brembo stopperz
 

wow neat stuff!
I also don't like having those big gaps.

Re: Brembo stopperz
 

Nice. I like the rays better than the motegies.

Re: Brembo stopperz
 

Finally got new seals and dust boots installed. Also primed and painted the calipers Brembo gold. (same color as the brembos on STi, 350z, and others) I just need to finish slotting the rotors, build some brake lines and install the Brembo stickers and these will be ready for installation.

BTW, LOVE this color.

Does anybody know if the evo rear calipers come close to fitting our cars? Id like to get a set of them for the rear to match the fronts.

Re: Brembo stopperz
 

No worries, either Volk ce28n's or AME TM02's will be going on the car but in an 18x9.5. Eventually the car will be getting a fender pull to fit the 9.5 wide wheels with a 275 tire. Until then I have to rock the motegies.

Re: Brembo stopperz
 

Keep an eye on Evo M for some time attack CE's...They pop every once in a while. In the size you are looking for as well.

Evo rears are a direct bolt on with Evo rear rotors and lines.

Re: Brembo stopperz
 

Does the 2g ebrake set up work with the evo rotors?

Steering away from time attacks, too much red/black with the car being red and black. Id like to get a set of ce28n's in diamond black or gloss black. For the most part I am pretty set on the TM02's in gun black.

Re: Brembo stopperz
 

Very nice. Those viper calipers seem waayyy easier to make a bracket for than the evo brembos.

Re: Brembo stopperz
 

Looks good Brian! Wanna sell it all to me? The gold would look good on a dark green 2g...haha

Re: Brembo stopperz
 

Looks good!

Re: Brembo stopperz
 

You should put viper stickers back on it. It'll make people think when they look at them.

Re: Brembo stopperz
 

Yep.

Re: Brembo stopperz
 

Thanks guys, it's more for show than anything but I cant wait to see how it stops. Im going to try my stock master cylinder first but I am sure I will have to upgrade that if I do the rear brakes too.


I was going to do that, but then they would have to stay red and I didnt want to add more red. It also seems a little cheezy in my mind, I want it to look like a kit or like it came this way. (like sti's, evo's, nismo 350Z, etc)

Re: Brembo stopperz
 

wow, very impressive. You should mass produce those brackets.

Re: Brembo stopperz
 

I thought it all looked like sex, until the gold paint. Don't get my wrong though cause it's still awsome. But if there going on a red 2g and black with a red lip rims. It doesn't seem like it would match you're color scheme very well.

Re: Brembo stopperz
 

Eh, I'd say black would look cool, red brembo stickers.

So do you think that tiny hub centric ring might get damaged or melt or something?

Re: Brembo stopperz
 

Well the rims will not be black with a red lip, just one dark color (diamond black,gun black or gloss black) They arent supposed to match, (you dont see them match any STi or Nissan) this is a factory Brembo color, that's why I chose the color. So they look like factory Brembo brakes. Plus I think they will stand out more behind a dark wheel.

The problem there is I had to machine the backside of the caliper mounting tabs becaues these brackets bolt onto the other side. Each knuckle ends up being machined differentley because you never know how much you have to take off until it is totally flat. So each bracket is made to each specific knuckle. People would have to send in thier knuckles to be machines and brackets made to them.

The liabilities behind making these and machining someones knuckle could be huge. I am no engineer so who knows what could happen though I am sure mine will be fine.

For me to make up for the time it takes to make this kit and for the parts (front/rear calipers/rotors/lines/brackets) I figure this kit would cost $2000-$2500 and at that rate there are better kits out there for less money.

Re: Brembo stopperz
 

You had to machine the knuckle? What was machined?

Re: Brembo stopperz
 

Nope, if you think about it, when you use it on wheels, it is touching the rotor anyway. I guess in my mind if they are on the front or back side of the rotor shouldnt matter.

I guess with track time they could be exposed to significant heat, but dust boots/pistons seals dont melt. The wheel/wheel bearing also absorbs heat. We will see, I think they will be fine but if they are not, I will make a set out of aluminum.

Re: Brembo stopperz
 

http://i244.photobucket.com/albums/g...Z/DSC02310.jpg

You can see it here, the shiny metal on the caliper mounting tabs, stock brakes bolt onto the other side. The back side that you see here normally has steel casting flash around the bolt hole. I had to machine them flat so the aluminum bracket could bolt up on this side instead because the rotor has so much offset to get the caliper away from the wheel spokes.

Re: Brembo stopperz
 

Oooooo, I see. I didn't realize that bolt on from the other side.

Is there a reason you didn't put the head of the bolt on the aluminum side of the brackets?

Re: Brembo stopperz
 

Yeah, personally, I would have kept the brakes painted how they were/left the viper sticker on. Looks unique that way.

Re: Brembo stopperz
 

Maybe this is a stupid question but, won't the rotor move a little bit since the wheel studs are smaller than the holes? Eventually won't all that banging around cause issues?

Re: Brembo stopperz
 

Brake rotors always have play and are able to move around until the wheel is torqued on.

Re: Brembo stopperz
 

Wow this looks awesome, nice project!

Re: Brembo stopperz
 

Im not sure I understand what you mean, are you talking about the bolt that holds the bracket to the knuckle or the stud that holds the caliper to the bracket?

Exactly, the rotor is centered, once the wheel is torqued on the rotor wont be able to move. The centering ring keeps it concentric so it doesnt matter where it is in relation to the studs when you put the wheel on

Thank you, it's allot of work.

Re: Brembo stopperz
 

The bolt that holds the bracket to the knuckle. Uh nevermind. I'm thinking the KNUCKLE has threaded holes, but it doesn't. And you threaded the bracket. So nevermind.

Re: Brembo stopperz
 

Looks good. I like the idea of ditching the viper emblem. Your not drive a shop car so no need to have them labeled that way. I'll have to forward this on to Mark, he is working on another Syclone project...

Re: Brembo stopperz
 

Got the calipers wet sanded and buffed with the decals on. Kinda thinking maybe I should switch to red decals like the STi's have. Idk, I can always peel them off and switch them later.

Re: Brembo stopperz
 

I like the gold/black combo

Re: Brembo stopperz
 

They look really good!

Re: Brembo stopperz
 

Awesome, looks very nice. Makes me want to repaint my Fadedbros.

Re: Brembo stopperz
 

Looks great. I was planning on doing a custom BBK on mine, then lost interest. Having a bridgeport has got to be nice, aluminum is a real pain to work with.
