This is what I have for an Eidolon of a Summoner 8 (Half-Elf with favored class adding to EP and one selection of Extra Evolution giving a total of 14EP).
Biped = +2 Natural Armor
8th Level Summoner = +6 Natural Armor
Improved Natural Armor (evolution) = +2 Natural Armor
Improved Natural Armor (evolution) = +2 Natural Armor
So that's +12 Natural Armor.
Now we have a base Dexterity of 15, but two selections of Ability Increase (Dex) make it a 19 and then add in the Dodge feat.
The Summoner has also given it a Ring of Protection +1 and Bracers of Armor +2 (only 6,000 gp worth of gear - pretty small change for 8th level).
So I'm getting AC 30 (touch 16, flat-footed 25) in total. This seems really high for 8th level. According to the Bestiary, that's an appropriate AC for a CR 15 monster. Am I doing something wrong, or are Eidolons just intended to have high AC very easily?

you've put a fairly heavy investment into ac, evolutionwise that is. i don't have my book on me but as far as i can see your math is almost right... the thing is, why use braces of armour when you can throw mage armour on it for +4 ac for 8 hours? that ups it to 32. throw in shield (share spells) and your looking at AC 36. improved natural armour (monster feat from beastery) adds even more...

Yep the math is correct but as fueldrop noted, its a heavy investment towards ac. Your eidolon will fall behind heavily in other combat aspects. Also about the bestiary reference, your eidolon shouldnt be compared to monsters since its a built in feature of a class that is one of its strongest points and customizable by the summoners preference. So if you want high AC i dont see anyone stopping you rulewise:D

I am not 100% sure about it but I think that developers stated somehwere on the boards that Improved Natural Armor evolution is not intended to stack with Improved Natural Armor feat (neither are Imrpoved Damage evolution and Improved Natural Weapon feat).

Before you get too worried about its AC investment consider that as it has been noted that is a very heavy investment and its going to allow for less of a damage focus.
Also note a level 8 animal companion Ankylosaurus has a starting AC of 27 before any feats are spent or anything else is applied.
You're not going crazy out of bounds.

For a pet, it seems way too high, but technically it's correct. It seems like most people are ok with the power level of the summoner, I'm not. Just look at what Fueldrop did with hardly any optimization at all, AC 36, give me a break. That's just broken imo, and no it doesn't matter if the pet invested in defense.

Make sure the summoner isn't wearing bracers or a ring; the summoner and the eidolon share item slots.
He's spent 6 evolution points and a feat on top of giving it defensive magic items. I don't know why he's doing that because he's at a high enough level where if it dies he has the summon eidolon spell.
Like FuelDrop said, I wouldn't have gone with the bracers because of the effectiveness of mage armour; I would have also worn the ring myself. The eidolon isn't being effective if all it has is high AC. That's why this isn't overpowered: he's just not going to do as much damage as he could have and consequently he won't be attacked enough to make use of that AC.

Summoners are really powerful. And that looks correct. I'd use a Mage Armor spell rather than the bracers for an extra +2 AC and not tying up the bracer slot, and you did invest a feat and 2 dex increases (only one mattered, though)... Also, by level 8 most people would want a Large eidolon, which also drops AC a bit.
Eidolons IME have better AC and damage per round than even a Fighter or Barbarian and can put their strength and CMB to shame. Summoners are really powerful...

Btw if you are hell bent on going with full AC build, you should consider taking Antagonize feat for your eidolon from UM. Eidolon speaks the same languages the summoner does, has an Int score of 7 at least, gets 6+Int skill ranks per HD and apart from the base skills the eidolon gets you can choose 4 additional skills to be class skills for the eidolon. Take Sense Motive, Diplomacy and Intimidate and voila! You have a nasty talking eidolon taunting your enemies to smack their faces into its high AC.

The Eidolon still has plenty of offensive capability. Here's the full set of evolutions:
Ability Increase (Dex) x2
Claws x2 [first set free as biped]
Climb
Energy Attacks (fire)
Improved Damage (claw)
Improved Natural Armor x2
Limbs (arms) [free as biped]
Limbs (legs) [free as biped]
Magic Attacks
Rend
Resistance (fire)
It's ability scores are: Str 19, Dex 19, Con 14, Int 7, Wis 10, Cha 11
Feats: Dodge, Improved Natural Attack (claw), Toughness
It's attacks: 4 claws +10 (1d8+4 plus 1d6 fire) with Rend
The Summoner has Evolution Surge used to turn it Large, making the attacks: 4 claws +13 (2d6 plus 1d6 fire) with Rend
The only thing questionable is having the Improved Natural Attack (claw) feat.

Improved Natural Armor x2
Improved Natural Armor (Ex): "This evolution can be taken once for every five levels the summoner possesses."
Feats: ... Improved Natural Attack (claw)
If the DM lets you use Bestiary feats, and if he lets it stack with Improved Damage.

For the first, check this out:
Summoner: What's the minimum level to take the improved natural armor evolution (page 60) for an eidolon?The description of the evolution says, "This evolution can be taken once for every five levels the summoner possesses." Unfortunately, that text is unclear.
A summoner can select this evolution once for levels 1—4, again for levels 5–9, a third time at levels 10–14, a fourth time at levels 15–19, and a fifth time at level 20.
This wording will be clarified in the next update document and print run for the APG.
Update: Page 60: Change the the Improved Natural Armor evolution to read as follows: "Improved Natural Armor (Ex): An eidolon's hide grows thick fur, rigid scales, or bony plates, giving it a +2 bonus to its natural armor. This evolution can be taken once at 1st level, and again at 5th, 10th, 15th, and 20th."

For the second, there really is no "if" - an Eidolon is a monster and there's no problem with a feat stacking with an evolution.

If the DM allows it in a home game, that's fine, but it's illegal in PFS.
http://paizo.com/pathfinderSociety/resources
Pathfinder RPG Bestiary - "Feats: none of the feats are legal for play for PCs, animal companions, or familiars unless specifically granted by another legal source."
Which specifically includes eidolons, per JJF's post here:
YuenglingDragon wrote:On page 30 it states that none of the feats from the Pathfinder RPG Bestiary are legal. Is that true only for PC's or may Eidolons and Animal companions also not take those feats?None of those feats are legal for any aspect of your character (companions included).

They should not stack. as essentially they are the same kind of bonus.
