E28 535i Hub assembly swap to get 5 stud

[2002maniac]

Yes, but i measured that the bolt holes are still on same pattern, so will it bolt with 3 bolts? Bad idea anyways.

E28 has brake caliper mounted on front side of hub, when e30 one is on back side of hub, that would most likely be a problem.

could you install the passenger side strut on the drivers side and vice versa. If you couldnt, you could always switch the calipers. i cant see how front mounted calipers would be a problem.

I may have to order one of the M3 lower knuckes to check this out.

I'm running E28 535i calipers on M3 strut housings. Same mounting holes but with a slightly (4mm) larger bore diameter.

[Rocla]

It won't. E28 and others use a 3 bolt mounting system while the E30 uses a 4 bolt.

No.

Fact? I'm quite sure it won't, but since those guys sell the arms for that purpose....

[PiercedE30]

No.

hmmm

Will the e30 m3 lower steering knuckle really bolt up e28 front strut housings?

[Eric]

i need those legs since i have E30 m3 struts now!

I researched this eariler, and came to belief that it doesn't work... I never spotted that page earlier, anyone?

$750 is a steal, realoem tells $184/side I know realoem prices can be very off, but 750 is insane.

EDIT: e28 strut has 3 mounting bolts while e30m3 has 4.

EDIT2: Asked the local price for "legs", 155e/each I think I'll be ordering on just to find out.

Come on guys, this should be the ultimate solution to achieve 5*120 and big brakes with low price and no one knows nothing about it.

guys i found this recently...mentions front legs E30 4 stud to E28 5 stud here:

http://www.bmauto.iinet.net.au/parts.html

looking at it...it seemed very interesting, E30 M3 front legs and u can have an E28 5 stud conversion....but i`m not exactly sure how it all works...

anyone??

no shit.
Guess what I have in my garage?
TWO E28's!! (one's going to be my DD, the other is a parts car. Guess I need some more parts, huh?
Now, if I can ever get my 535is going, I could actually check the validity of this for you guys....
Stay tuned!

i believe the reason here of using the e28 rear arms are for the strength you need if you using 300+ hp..
a friend of mine used structure foam on the subframe and arms and it added some strength to it..

maybe it works..

[Rocla]

you are asking if the e28 control arms fit on the e30 subframe.

no. the second reason to do this swap, asside from the 5-lug, is because of the better swing-arm angle. e30's are 15 degrees (which induces too much camber when car is low/loaded) while the e28 is what guys? like 10-12, something around there?
the next question is could eccentrics make this happen and then also, is the two mount points the same width appart?

The idea I was talking involves complete subframe swap, not just trailing arms. The Big subframe mounting bushes are the ones which are custom made.
