Are the stock Evolution Brembo 2 piston rear calipers the same from the Evo 8 and the Evo 9? Does anyone know what the piston size is on these rear calipers?

Also, I would really appreciate it if someone could measure the center-to-center distance of the caliper's mounting holes. I'm trying to see if these calipers will line up on a different application

yes they're the same, i don't have measurements though

Ericsworld

Could really use those measurements!

What's the best place to buy these calipers used?

wrecked car here on the forums or ebay

I believe STI's from 2006-2007 have the same brembos as the evo

Fronts are the same, I've read (so don't quote me ) that the STI's had different sized pistons in the rear from the Evo, IIRC the STI had smaller pistons.

Interesting, I'll give the STI calipers a look too.

The Evo X rear calipers have the same mounting points but bigger pistons, right?

No, Evo rear are different, they don't bolt on in place of 8/9 rear calipers. The fronts you can, but the hole in the spindle has to be drilled for the larger 14mm bolt that the X front calipers use. And with the X caliper, you need to run the larger, 13.8" X rotor..

Good to know, thanks.

I found out that the Evo X's Rear caliper mounting distance is 146mm center-to-center

Would be really helpful to find out what the Evo 9's rear caliper mounting distance is.

call up MAP, STM, CBRD, etc. and see if someone there can measure

Actually called up a couple scrap yards and was able to get one of them to help measure, Lol.

It's 5.5" hole to hole it seems
