mikeshoup Posted May 23, 2007 Share Posted May 23, 2007 What's the chance of fitting EA82 front brakes on an EA81? I would think changing the knuckle and then using all the brake stuff from the EA82 would work. Is the strut mount different? If so, then the EA82 strut with EA81 top mounts? And just how much bigger is the EA82 discs than the EA81 discs? I know they're bigger, but just how much? Link to comment Share on other sites More sharing options...
Matty B Posted May 23, 2007 Share Posted May 23, 2007 Yep they fit. Strut mount (lower) is identical. Yep they are bigger. tie rod ends are your only grey area... grab a few different ones from the junk yard and experiment, there is a combo that fits. Big difference in performance ...Lego for the win. Link to comment Share on other sites More sharing options...
Phizinza Posted May 23, 2007 Share Posted May 23, 2007 So vented EA82 front brakes are bigger then vented EA81 front brakes? I know the solid ones are smaller but never compared vented with vented. Interesting. Link to comment Share on other sites More sharing options...
mikeshoup Posted May 23, 2007 Author Share Posted May 23, 2007 So vented EA82 front brakes are bigger then vented EA81 front brakes? I know this from deduction. EA82 wagon wheels have sharper curves on the edge of the spokes so they can clear the calipers. Link to comment Share on other sites More sharing options...
PoorManzImpreza Posted May 23, 2007 Share Posted May 23, 2007 hmm should work..you'll need ea82 rod ends as ea81 won't fit the ea82 knuckle I have no idea of the length difference, if any, tho' Kaz Link to comment Share on other sites More sharing options...
cyberbackpacker Posted May 23, 2007 Share Posted May 23, 2007 I know this from deduction. EA82 wagon wheels have sharper curves on the edge of the spokes so they can clear the calipers. So, following this logic, one would not be able to run stock ea81 rims then after this upgrade? Link to comment Share on other sites More sharing options...
Numbchux Posted May 23, 2007 Share Posted May 23, 2007 So, following this logic, one would not be able to run stock ea81 rims then after this upgrade? that's very definitely true. Link to comment Share on other sites More sharing options...
mikeshoup Posted May 23, 2007 Author Share Posted May 23, 2007 So, following this logic, one would not be able to run stock ea81 rims then after this upgrade? Correct. You have to be running rims that will clear on EA82s. Luckily, that's all I have (my EA81 rims are bent) Link to comment Share on other sites More sharing options...
86BRATMAN Posted May 23, 2007 Share Posted May 23, 2007 I've seen pics(in the Carlisle thread) of an ea82t wagon with the 84 turbo 4-spokes on it. Maybe the alloys were made with more clearance Link to comment Share on other sites More sharing options...

waimaks Posted May 26, 2007 Share Posted May 26, 2007 yep. it's just the wagon wheels. So ordinary ea81 and prior steels would probably work too? Or is this another grey area? Link to comment Share on other sites More sharing options...
86BRATMAN Posted May 26, 2007 Share Posted May 26, 2007 The standard silverish steelies would work I believe. The ea82 cars had them and I don't think there was much variation from the earlier design. Link to comment Share on other sites More sharing options...

Didn't the offset change b/w EA81 and EA82 ? Dean. Link to comment Share on other sites More sharing options...

carfreak85 Posted June 3, 2007 Share Posted June 3, 2007 I don't think it did. Also, wasn't the difference in wagon wheel spoke profile attributed to the EA82 using a different caliper than the EA81 or am I wrong? Link to comment Share on other sites More sharing options...
ruparts Posted June 3, 2007 Share Posted June 3, 2007 Hi, This is a project I have been intending to do for a while , I did measure some parts for it, the knuckle will fit the ball joint and it appears to be the same in height and the arm for the tie rod is the same. But the ea82 strut diameter the part that clamps, is bigger than an ea81 by about 100 thousandths of an inch. So I am going to disagree with matty B that it all fits. They sure look the same but definately are not.If you use the EA-82 strut though and the Ea-81 tops, but springs are the one issue that is in question. I think either will fit but ride height is unsure, and I cant remember the spring rate difference right now. This is further confused by the dimention of the struts from where it clamps and the spring seat on it. I am checkin those next, just looking for time to do it, I have all the stuff. My 84 wagon should stop well with EA-82 discs all round. Bquote=mikeshoup]What's the chance of fitting EA82 front brakes on an EA81?

monstaru Posted June 3, 2007 Share Posted June 3, 2007 they will fit.i've put ea 82 struts with ea81 strut tops onto ea81 knuckles.and never had a problem.i've also used ea82 springs on ea81 struts.and vice versa.put away your calipers and do some fabbin/modifyin cheers, brian Hi, This is a project I have been intending to do for a while , I did measure some parts for it, the knuckle will fit the ball joint and it appears to be the same in height and the arm for the tie rod is the same.

Bquote=mikeshoup]What's the chance of fitting EA82 front brakes on an EA81? as far as the rims go.all it takes is a little grindin on the caliper itself to clear them.if you mount the wheel and turn it a little(if possible).you should see a mark on the caliper .then remove material as needed.it is not a vital part of the caliper.it is simply pot metal anyway.just do it.if you ************ it up get ahold of me and i will give you another damn caliper.cheers, brian I would think changing the knuckle and then using all the brake stuff from the EA82 would work.

mikeshoup Posted June 4, 2007 Author Share Posted June 4, 2007 put away your calipers and do some fabbin/modifyin cheers, brian That's my attitude right there! Once I get the parts, I'll try this out! FYI: Parts catalogs show the EA82 rotors are about 1/2 inch larger than the EA81 rotors. Should be good for some more braking powar!
