I just like to share the solution for for jdm knuckles with the forums. This is how I got the evo X\8 calipers on my 2g knuckle. I was looking for jdm knuckles but there like $500. I had a few set of 2g knuckles and one evo X and 8 calipers lying around. Then I thought of this idea. First I machine flat the back part of the knuckles. Now I have workable surface to make brackets. These brackets could be made out of 3\8" steel or 1\2" T6 aluminum on a CNC machine. The bracket I made will fit the evo X\9\8 Calipers with one exception that evo X calipers must be used with the X rotors and vice-versa with evo 9\8. These pictures are evo X calipers and big 14” rotors. The evo X brakes will require 18" rims minimum, i went with evo 8 calipers to save my 17” rims\tires. Here's the tech artical on how to shave the knuckles. Shaving 2g Knuckles to make Brackets for Evo\CTS-V Brembo Calipers

Looks good. The idea regarding the mounting bracket has of course been discussed, but not many people take that route, for a number of reasons. Let us know how it works for you.
i have been doing some thinking about these and came to the conclusion that i would never put these on my car... while i think its an awesome new idea i think there is a flaw. 6061 T6 aluminum which i am assuming is what these are made of, i dont feel that material will hold up the the stress that will applied to it. now i am no metallurgical engineering but i do have some experience with metals. if you see where the caliper bolts to the bracket to me that appears to be a serious weak point. i think if these were made out of steel i would trust them alot more and i would think they would hold up.
anyone else feel similar or hae experience with metals and want to chime in?
I've seen kits sold with aluminum brackets so they are probably strong enough. Also, it looks like it may be possible to throw in two more bolts where the original caliper ears are. Just need to drill and tap the bracket. As long as the caliper mounts don't overlap.

Don't worry these brackets are overkill there more beefer then most aftermaket adapter out there.The bolts thats holding them are m12 much stronger then the m10 bolts on the ears that other brackets uses. look at these made out 1\4" t6 aluminum being sold. This route is only good if got the brembo for dirt cheap like i did. like i said is not the cheapest way to get brembos aleast now we know there are more options.
for safety why not put bolts in threw the original caliper mounts on the knuckle also in addition to the hub bolts? If this is done it would also be a good idea to put more material where the arch of the caliper is.
are the evo X calipers the ones with the 38/42 mm pistons?
It does look stronger than the aftermarket parts I have seen as well. Steel would be nice, a little heavy, but nice and if your really worried you could spot weld the bracket in place as well.

1\4" steel would have been as strong as 1\2" T6 aluminum and cheaper too. You can weld them up to be one piece but people like bolt on. This design is good the way it is. Sure you can add more bolts to feel safer but comparing to most brackets out there this should be over kill. about the x calipers i'm not sure what piston size are they but the are a bit bigger and longer then the 8\9 and the pads are biger too.
I think what they did was shrink the piston size on the x calipers a bit and increase the rotor diameter for about the same braking torque. I doubt they used the same 40/46mm diam pistons on the x because with a 14" rotor the braking torque is nearly 62 k inch-pounds which is ridiculously high and would snap thoughs little 10 or 12mm bolts on the hub in a hurry under hard braking.
I don't want to tell you what to do with you project but I would regard the extra bolts as a necessity.
I bet the braking torque is close to the 8/9 , can you find out the piston diamters?

your right, i measured the X cailpers they look like 36 40mm. so what's the point of bigger rotors smaller piston and how about those 6 piston brembo gt upgrade kit that uses 10mm bolt on there adpater too.
are you serious? lol so they are essentially cts-v calipers with a wider mounting distance and different casting.
if your right then mitsu essentially decreased the braking torque for the x. I'm not sure on the argument for smaller diam pistons with a larger rotor, it probably has to do with response time.

actually there 43-44 mm and 36mm i measured it wrong. I also found out that 6061 t6 aluminum(35k psi) is almost strong as mild steel(40k psi) and 1\3 the weight.
Do you know if the rear brake rotors and calipers will bolt up to 2g like 8 and 9 do?
The rear evo X calipers would fit on 2g rears with a lot of cutting of the back plate and porting out the holes. Evo 8\9 rear rotors have to be used for this swap. Once every thing is done it actually fits better then the 8\9 rear does because it’s perfectly center not off by a couple millimeters like the 8\9. I would recommend the evo 8 calipers over X; less work, fits in 17" rims and cheaper rotors. The only good thing about the X is you know it can’t have too many mileages on it.
So is there any need to run wider wheels with this setup like most of the aftermarket kits they have available?
wider? or taller? like 17"
i dont think the width would really matter just the right offset so the spokes would clear the calipers, and a 17 woud be the minimun heigth you would need to a evo VIII/IX calipers and 18" rims for the X brakes.
just pick up Evo VIII/IX rims and they will be sure to fit over the VIII/IX brakes lol
Apex - I already know that 17" will fit with the evo8/9 brakes....he also said it in one of his earlier posts. I was talking wider. When using the JDM spindles, you have to run a minimum of an 8" width wheel and even then you might need to use a spacer. With the other style adapters, the offset didn't make any difference. You can run the evo 8 wheels but not everyone wants to do that. So my question does remain the same but rephrased - Is there any need to run a 17x8 or can you run just a regular 17x7.5 with the way you have set the bracket up?
An I don't like the evo wheels. They just don't do it for me.
