(Stolen from Krinkov)stock rear. Sti rear Brembo with EVO rear rotor : and it BOLTS RIGHT UP!! : it needs a 3mm spacer here for the correct offset, you need to trim/remove the dust cover thats all, the brembo brake line even screws right in! For comparison.

going to be running the matching EVO/STI brembos up front, so hopefully balance should be the same or pretty close, might have to run a wilwood valve if they feel out of balance, heres some shots of the front in progress:) stock EVO

Man this swap just keeps getting easier!:DPicked up another set of STI Brembos yesterday, and it looks like our best route will be to use the EVO front rotors instead of the 05+ STIs(5X114) the STIs use a smaller center hub opening that wont fit whereas the EVO is spot on, so we'll stick with plan A. Heres what the EVO rotors look like with the STI Brembos, oooooooooohh! : Brembo F50 calipers are truely MASSIVE, much larger that what in hand than what you can see of the sides of them poking through the spokes of a wheel. Now about the easy (*fairly*) easy part I mentioned, looks like the brackets are going to be simple to fab up, matter of fact thay can be made yourself if you have a quality drill press and drill vise, no machining necisary! Most big brake kits have brackets shaped like kind of like an "S" since the new caliper and has be moved up and backward(inwards) to bolt to the stock caliper volt holes. In our case with these Brembos and EVO rotors, the Brembos sit a good .6" outwards ofthe stock bolt hols, on top of that, the stock bolt spacing(4") and the brembo bolt spacing(6") are far enough apart that we can make the bracket on a single-plane bracket, instead of a dual-plane bracket which requires much more design and machining, see here:) heres a quickie MS paint diagram of what the single-plane bracket will look like, not to scale obviously but the measurements are correct, Im going to fab one out of aluminum tonite to get everything where I want it then I will make mine out of mild steel. I know alot of the brake companies use 6061 AL with no probs but mild steel gives you that much more insurance, and its not that much harder to work with. Okay I'll post mor eas it progresses!the stock STI rear line plugs right in, if one didnt come with your brembo caliper then grab some steel ones. got a bit more done tonite, just have to tap 2 holes and they're ready to go on, these ones are ugly for sure, machined ones will be nicer. though you can make these in about 2 hours with just a small 1/3 or 1/2 hp bench top drill press like this. one more hole still missing here, these two inner ones are the ones to be tappedOkay done....mostly:D finally tried my new FN01R-Cs on too, used to think my car was low enough, now it looks goofy high! Guess I'll have to drop it down another inch:D

and the bit of my own work that i did:try this: 2007 STi Brembo Brake Kit All Calipers All Rotors Wrx:eBay Motors (item 300343525459 end time Sep-30-09 10:22:00 PDT)

well you can get em cheaper:$1100 (2006 IMPREZA WRX STI BREMBO CALIPERS EJ25 EJ20 GD7 GDB:eBay Motors (item 330358418826 end time Oct-07-09 13:45:43 PDT))then you gotta get evo rotors,$ 790 for all 4 (Brembo Drilled Brake Rotors Set: EVO 8/9*::*Brake Rotors*::*Brakes*::*LancerShop.com | EVO Performance Experts)

that ends up being a sub 2k brake upgrade for ALL 4 brakes.

if you want E-Brakes buy from: http://www.240sxforums.com/for....htmlthats an extra $180

So now you have a full functioning 4 brake set up from Brembo for $2070. For that same amount of money you could get a KSport 12 inch front brake kit. Its a great value.

So its pretty much a very cheap brake upgrade, IMO its better than a Z32. Z32 Ebrake assembly works with the brakes.

the point here is you get big brakes with minimal work and minimal money. In the last section i show how to get the whole setup for about 2k for ALL FOUR brakes. Thats about what ONE K-Sport big brake would cost. All you need are 2 manufactured brackets (for fronts) and two 3mm spacers for rears.

The Z32 EBrake assembly fits. Both are 172mm drums.

These require 17 inch wheels at the least. (http://img223.imageshack.us/img223/8950 ... 0677zr.jpg with 16 inches the caliper would scrape)

2003 and newer rotors work (Evo VIII and IX).

PS: another fun fact - the STi brembos are F50 which are larger than that F40 used on the 350Z

Im thinking that it would work, but i haven't tried it out myself.

If you could try it out and get back to me, im sorta curious myself. For reference those are 05+ STI brembos.

anyway to not use z e brake? ... like a second caliper in the rear only for ebrake with a cable

ex: sti rear calipers .. and 240sx calipers for ebrake only .. ( my friend told me about this .. he's seen it on another car)

The ebrake drum diameter on the evo rotors is the same diameter as the 300ZX, the 240sx would be too small. It'd be like trying to use the 240sx ebrake with a 300zx brake upgrade.

Just put that b**** in 1st gear. Emergency brake problem solved. lol

Oh yea, you said you need 3mm spacer for the rear calipers and then later on you said "two 50mm". Care to clear that up for me? Thanks

im afraid i've never tried evo calipers, theoretically they should fit the same way (the STI rotors have the wrong pattern while the Evo rotors match perfectly)

Are you fabricating and selling any of the brackets?

no, this diagram should help anyone trying to make them:



my latest project will be trying to get the Z06 6 pistons to fit, IIRC they have the same spacing as these brembos and they can be bought for $200 a piece ($800 for all four calipers)

yep I can't believe I let a pair slip past me. I didn't have the money for them but they were only $80!!!!!! really sucks sometimes.

What I did get is a rear pair from a SRT-8 I think they are F50s but no telling till I do all measurments paid $160 for a pair of those and I got a pair of rear Evo for $150 here on Nico.

That guy still has a Pair and a half off Evo $400 for a whole set!!!!! thats cheap and you know it will work. Plus he's a great guy to deal with.

I'll be adding to this post if I find anything out. Hopefully within the next couple of weeks I still gotta buy rotors and break lines and master cylinder.

So thats quite a bit of money alone. probably $350 atleast for all that but I'll still be rocking Brembo rather cheap.

I'll be using mustang cobra rotors not Evo in front but Evo in the rears for sure.

nice job but the 300zx brakes is more affordable and a bolt on (except the parking brake).

actually the 300z ebrake is a direct bolt on if you get creative with it. run the z up rights and custom rear coilovers with r33 e brake cables. but i know that not everyone can afford all of that! and reguardless this is still a pretty sick brake up grade!

or you could take J30 spindles and bolt them on and cut the J30 or Q45 cables then have a cable shop crimp it onto the old ones.

Q45 just use the backing plate.

Also you can get the drum brake park cable off a Sentra and use that.

Then when you find some Z calipers and rotors put them onto the new spindle or backing plate.

Thats if you don't just use Z backing plates.

Well the Evo rear deal didn't go through I sure thought it was going to

I'm gonna try smaller 4 piston Brembo and they don't bolt on like STI but niether do Evo. They are similar in size but thinner than the Z calipers and I can actually shim the pads to be safe. 16 pistons of brembo stopping force is gonna be awesome if I can get the bias right

I might see if I can get some easier to find front calipers and make a kit we will see what happens
