Not sure if many went to the X calipers and those that did had Galant knuckles i sold them and re drilled for the 14mm bolts. Other then that its likely just adaptor brackets like the other brembos. But not zure if the X calipers need grinding down or not due to the longer ears on the caliper

We looked into this project a while back. As far as we know, the only meaningful difference between the EVO X calipers and the EVO 5-9 is the mounting bolts are 14mm (as opposed to 12). As far as we know, you can use brackets intended for the EVO 5-9 upgrade (and as ec17pse suggests), and drill them out to 14mm. You also have to use EVO X rotors. We never actually tested this setup, so we don't know if there are any interference problems and the like.

I got a set of galant front knuckles from bobby for my evo X brake upgrade. Did have to drill out bolt hole locations for the larger evo x bolt size on the front and rear. You will need evo X front rotors but use evo 8/9 rotors for the rear. Just make sure you have at least a 38 offset on your wheels and 18"s. The X calipers are beefier and I couldn't get either sets of my 17's to fit at all. IDK about keeping the stock dust shields. I pulled mine off to tweak but I have a new set of evo dust shields I had planned on using. I never got around to it, but it's been just fine without them. Upgrade to the 3g Brake master cylinder, didn't need the brake booster.

Awesome I will be attempting this conversion

I can tell you 100% from experience that the REAR will not direct bolt on like the Evo 8/9 rears will. For the rear you will have to dremel out the mounting hole in the dust shield slowly to align with the Evo X mounting locations. And then as stated earlier, you can use the Evo 8/9 rotors.

Thanks, I think I'm just going to swap my front calipers for now

Just to kinda clear this up about the rear calipers, evo 8/9 will bolt right on just the 2g or does the same apply for the 1g? Other than the ebrake issue on 1g ofcourse.

Hey buddy do you still sell knuckles? Finding them online for less than I paid for the car is a pretty hard ask for knuckles

I have a spare set i could sell on. They did get expensive as galants are trying to stay alive now to rising chassis prices. Not many scrapped anymore. Pm me if you wish to discuss

Sorry about the dumb question but can somebody tell me if I have Evo X or Evo 8 calipers?

I’ve read the other 30 page post and someone said Evo IIX rear calipers measure 5.125” center to center and Evo X Measure 5.65, mine don't measure either. I've also looked for size differences and comparisons (pics) on line and found nothing.

Any help will be greatly appreciated. I bought front and rears calipers, rotors, brake pads, brake lines and mounting brackets for $700, SHIPPED! I thought it was a good deal now days. That's why I think I was sold Evo X set up. This is one of those times when I hope I’m wrong.
Thanks guys!

You do realize the .020 difference you're seeing is the thickness of a .5mm pencil lead? The way you're measuring just eyeballing center and laying the caliper on it won't yield the precision necessary. You likely have an evo x caliper.

Thank you. Yes, I understand is not the most precise measurement on my part, sorry about that..

Awe man, I hate it when people do that!

Another easy way to tell which rear calipers you have is by the bolt size. Evo 7/8/9 use m10 bolts, the X uses m12.

https://www.ebay.com/itm/2050485449...lp:2332490&itmmeta=01KV2B0CXNWRE9N7HQ2SQV1E81 used these adapters. I do remember having to grind a bit of the knuckle and the rear of the calipers

Very cool! Thanks for sharing!
