Just want the title says i think ill have better luck finding an EA82 at a yard than an EA81. I need new rotors and calipers since mine is a 83 with non-vented rotors and they are warped. Are EA82 vented rotors the same as EA81? Calipers bolt on? Or is everything in there pretty different?

They are different - the EA82 stuff is larger. I don't think the caliper will bolt to the EA81 knuckle.

Damn...knew that would be too easy. Thanks for the quick response GD.

You could switch to full EA82 front Knuckles. Although I believe there is some issue with the balljoint going that method. It is doable though.

The inner bearing seal is also different on the EA82's IIRC. But you could likely just use an EA81 inner seal and it would be fine.

 

The ball joint's are different. The EA82 ball joint doesn't work in the EA81 control arm. There are ways around that but it does require a bit of fabrication to overcome.

Also, if your wheels are of the 8 spoke variety, from an EA81, they will not fit over the EA82 caliper when the pads are new. If the pads are worn about 50% or so the original wheel will work.

By 8 spoke variety do you mean Enkeis? I have aftermarket Enkei wheels so they might not clear the caliper. At any rate thats more work than i was hoping for just for a set of decent disk brakes. I guess ill cross fingers that there is an EA81 in the yard with vented rotors so i can at least grab the calipers.

If I were you, I would just buy a brand new set along with new rotors. Rockauto has loaded front calipers for $47.79 each (Beck/Arnley - which is often repackaged OEM). It's just not worth the trouble to buy used one's with these - the integrated parking brake makes them a pain to rebuild if you don't have the right tools and by the time you add the cost of the used one's plus the rebuild kits plus new pads plus your time..... I'm not thinking you would save more than $50 tops. Just not worth the frustration.

I agree with GD. Tell them your car is an 84 so you can finally start running vented rotors.

Yea i was more asking for the actual rotors and stuff since im short on money. I think i will just save up and get rebuilt calipers and new rotors. I can get a pair of drilled and slotted for 100 bucks on ebay. Not really sure if its worth it or not though since i can get normal ones for the pair for 40. Extra 60 bucks....
