E28 Coilover suspension DIY (in progress)

[iamsam]

My bad ok e34 rear brakes with front e32 brakes makes a big brake kit on e28. I have that set up on mine e28. For a plus also add like slammin.e28guy said MC from 750 to complete a nice brake system.

So E34 front brakes don't work on an E28?????

So much conflicting info... I am just going to find out for myself. I have an E28 and an E34 540i parts car...

Found this on myE28, apparently you can get the entire E34 front suspension to work on an E28. http://www.mye28.com/viewtopic.php?t=78698&

Brakes bolt up. That's about all I'd worry about from a e34. I see no advantage in swapping anything else e34 -> e28 except a B35 swap or a M1.3 upgrade.

As far as suspension, SPAX. That is all.

Well the whole reason I started this thread is to finsd a cheaper DIY option for a coilover setup for an E28, and that is what I want to stick with, for the height adjustment and the quick spring rate interchangeability.

Interesting. Still, no specifics on what DOES and DOESN'T fit in detail, since I hear that E34 540i brakes bolt up...

What about a 540i suspension does not work? I heard that it does on myE28...

[slammin.e28]

Does E34 540i suspension bolt up to an E28? front AND rear?

No

Why E32 750? just bigger brakes than the E34 540?

Master cyl bolts on, bigger. Brakes, IIRC are bigger, but really, e34 brakes are more than enough, especially with a 750 MC. Do some SS brake lines while you're in there and make sure you tape your face on before touching that brake pedal.

@iamcreepingdeath I am aware of the rear hence my question. I was not sure some knew. As for brakes from e34 they fit for those whom are wondering rears tho and use e32 750 in front and you have ur.self a bbk.

I am looking into doing some coilovers in the next few months for about 8-900. I would love to do ground controls, but I am a poor college student.

I was looking into piecing a kit together, whether it be GC or IE adjusters, a shorter shock (I have heard G60 VW Shocks work, not totally confirmed yet), and some fabrication. I then started looking into it a bit more, and Nex actually makes a kit for the E28. I knew they made coils for the E34, but now I have been seeing more and more for the E28. They are $799 shipped on ebay. I think this is the route I may go, as for what I need, they are good enough

Okely dokely. I definitely saw on Realoem that the E28 has 82mm and E34 83mm, but it must've been referring to something else hub-related

Yeah I think it was, I think it has something to do with the wheel bearing cap dust cover or something odd like that.

about halfway down the page here it says what the E28 hub diameter is: http://www.scrappycrow.com/e28wheels...eelstires.html

Near the bottom of this page is talks about E34 hub diameter: http://www.bmwe34.net/E34main/Upgrad...ls_upgrade.htm

Check Realoem.com

Realoem has no such information.

According to some quick searching just now, both E28s and E34s (along with a heck of alot of other BMWs other than the E39) have a 72.5mm hub diameter.
