Evo 8-10 Brembo Calipers DSM Conversion (for 1g too)

[m_0ney_pit]

after a series of measurements, the largest rotor the evo 8/9 caliper can handle before the pads must be moved down is 13.25". This is not ideal though as there is about 1.5mm of clearance between the housing and the rotor so we should aim smaller.

in my opinion a 13.1" rotor is ideal for this swap 1.) to take advantage of the larger torque and 2.) to space the caliper sufficiently far away to minimize milling.

if we could find a 13.1" or 13.2" rotor this swap would probably become easier. The only issue is the thickness 1.1" vs 1.3" and a 18" wheel being required vs a 17".

Using 0.1" shims behind each pad made from steel(not aluminum! its to soft) will elliminate the thickness issue. This is acutally ideal since the 1.1 is lighter than the 1.3.

KMV - could we have an option for people with 18" wheels to use the 1.1" thick cobra rotor(with shims included) and that would not require milling?

EDIT: looks like the Lexus 2007+ IS350 has a 13.15" rotor with the 114.3 pattern. The height is 2" (0.3 more than evo 12.6) and its 1.2" thick. the hub ring is 62mm.

Believe it or not, putting these calipers with the cobra 13.1 rotors might increase the milling as the cobra rotor has a higher offset then evo rotor. Where the ear overlaps the calipers has to be counter sink deeper. The only way you could escape the overlapping is to put them on 14" rotors but the housing won't accept 14".

1) 13.1 vs 12.6" is not much torque difference that you can notice. The evo combo are excellent to start; no one is complaining about its performance.
2) Cobra rotor is not hub centric with dsm hub and the lug holes on those are a lot bigger too.
3) You will loss the benefit of thicker evo rotors.
4) both rotors in stock format weigh the same even thought the cobra is thinner, ~20lb each
5) Have to make 4 custom shims.
6) may not clear 17" rims.
7) The overall swap cost will increase due to hub centric rings for the rotors and shims.

But if you can find enough people that like to go against the odds, I can help.

 

[m_0ney_pit]

does anyone know what the diameter of the hub circle is on the rotor?

 

[kmv]

Dsm\mitsu front hub flange for the rotors is 2.72" = 69mm.

 

[Guzman08]

what other brembo calipers fit. what about hyundai genesis coupe or charger srt8

also would they fit with these rims.

You could get those custom fitted on to any car if you wanted to.
These evo brembo were never fitted to start, they were custom fitted.

I have the cobra brakes on my car, and if i read your post right, you do not need 18 inch rims to fit the 13.1 inch rotors behind them. http://www.dsmtuners.com/forums/cus...0-cutting-welding-caliper-bracket-2g-awd.html check that out. This was my install for my CHEAP big brake kit. I have not tested them out on my car yet, but my friend with a 95 GST has them, and it stops insanely faster then the 2 pot awd calipers.

Dont mean to bust your thread up KMV, but i figuired dsmers should know all their options..

 

[kmv]

Don't worry you didn't busted this thread, I'm sure 99% of the people that does this upgrade are aware of the cobra set up and I almost went with that set up too.
Here quick comparison between the 2 set up. Evo brembo 4 piston(46\40mm) fix calipers on 12.6" rotors Vs. Cobra 2 piston(40\40mm) sliding calipers on 13.1".

btw the reason why your friend notice such huge improvement on his upgrade because he own a gst\fwd which has the shittyest brakes out of all dsm.

Either way is fine. With the caliper\bracket clocked upward, the grinding job will be a bit harder thought. Also have to port\mill out the bleeder end of the caliper instead of the end with the looping tube. Plus you have to tap the top ear and use one Allen bolt for the caliper instead of hex head bolt.

Well, i got my calipers all mounted up finally. And wow, your right about the grinding job. I had to take away alot of meat off the calipers. I Have them with the end with the hole for the brake line towards the top. Also, i realized about the bolts being too long wihich hits the rotor, all i did was buy a locking and regular flat washer and it works fine now.

 

[kmv]

Did you had to use one allen bolt instead of a hex for the calipers to get the bolt to clear the knuckles?

 

[VETTE_50_TH]

Did you used one allen bolt instead of the hex on the calipers to get the bolt to clear?

I used the bolts you gave me. Ill take some pics today. I made sure everything cleared with my new rotors yesterday. I would just send some washers from the hardware store with your setup.

 

[Guzman08]

ok well the genesis rotors are 13.4 is that too big?/

and the rotor size for a srt8 is 14.2.. isnt the cts-v swap a 14 inch rotor

 

[VETTE_50_TH]

Yea. The most you could fit under his bracket is maybe a 12.8-13.0. Maybe. It would require a new bracket design for a larger rotor like that.

 

[Guzman08]

so niether of those would work?? dam

 

[VETTE_50_TH]

Just get the stock rotors off an evo. Have you ever felt an evo brake? Its already good enough. If you want more brakes, get some good pads, SS lines and good evo rotors. Youll be set!

 

[Guzman08]

the thing is i can buy these brembo set for about $400 and i kind of want to know if they would fit

 

[VETTE_50_TH]

Off of what?

 

[Guzman08]

2009 hyundai genesis coupe. rotor size 13.4 and 5 lug rotor.. but those rotors wouldnt fit

 

[VETTE_50_TH]

What are the bolt pattern on the brembos? You would have to measure that to see if you need a bracket or if they bolt up to our hub.

 

[Guzman08]

not sure..

 

[kmv]

Come on guys, lets try to keep this thread evo brembo and dsm related.
Please no more question on will this calipers fit or will these rims fit. The only way to find out is trying them on your self; no one is going to give you a straight answer and be reliable for it.
If you want to open up new possibility on other caliper option please start a new thread and I can drop by and help.

 

[m_0ney_pit]

13.4" is going to be to big for the evo brembo calipers. any diameter of larger than approximatly 13.25" will require moving the pads down using a bracket at the pins. kmv already determined that using a 13.8" rotor requires no milling of the caliper or the knuckle.

Another idea is to use custom pads from porterfield which have the friction material moved down to use 13.8" rotors. I dropped the ball on this but they do make custom pads for poeple. They require a drawing so someone thats good with cad would have to copy the stock pad and then extend it down some distance (based on measurements approximatly 8mm).

I finished installing my Evo IX calipers on my 1G DSM today...

After lots of grinding on the calipers and a little on the knuckle and buying some washers, everything is mounted up fine....

Pics and details to follow soon.

[Guzman08]

that was for other brembo calipers. hyundai genesis.

Here's my most recent upgrade:

I haven't really driven the car any yet with the new brakes. I haven't had time to bolt the downpipe back up to the car yet so I can take it for a spin.

I'll update on how it feels/brakes soon.

Also, ignore my messy calipers on the backside..... :: I ended up grinding both ends of the caliper on accident and used some VHT high temp paint I had laying around to cover the grinded areas to protect them from rusting..... all I had was silver paint. (nobody sees that part anyways).

As for the installation, it went pretty easy>> Buy KMV's kit, buy Evo calipers, I bought SS brake lines --
1)grind caliper
2)grind a little of the casting off the top knuckle ear
3)tap top ear with 12mmx X 1.5 tap (I got mine at Napa)
4)had to buy washers to put on the two caliper mounting bolts so that they didn't go too far through the caliper to the point they rubbed the Evo rotor.
5)put locktite on bolts and tightened everything up
6)bleed brakes and slap the wheels back on the car.

That was it, DONE!
