Subframe Question.

[z122643]

I can't find the original post on this so sorry for the repeat.

I am finally ready to replace my (very rusted) rear subframe.

The question is what is the difference between the normal E30 rear subframe and the iX?

Can I get away with using a normal E30 subframe?

**If anyone has a no rust rear subframe for sale, I'm interested.

different bushings

the IX subframe bushings are different so you would have to change them in the new subframe if its and i/e, other wise its all the same.

the reason the subframe part # is different on sites like RealOem is the the subframe comes with bushings installed so had to have a different #

i just converted an i subframe to an IX for my car to fix a toe issue ,just pressed in new IX subframe bushings

Is that really all? Wow... ok then that make my life much easier.

Yeah that's all. Just use ix bushings with the ix Subframe washers/Subframe bolts and everything will line up like normal.

[spdracrm3]

yes thats all , the subframe bushings are taller to correct suspension geometry due to the IX sitting higher ...(lowers subframe in relation to body) , and yes be sure to use IX washers if staying stock height, if lowering car you can use standard i bushings/subframe to keep geometry correct due to sitting lower (close to same height as stock i)

I need a new subframe and trailing arms for my 'iX' because
I smashed a curb sideways and bent an arm and the arm mounts on my subframe. Is this confirmed accurate? Can i just buy an 'i' subframe and use the 'iX' bushings?

Yes

you will need to swap the rear hubs/e-brakes on those RWD trailing arms. may as well do new bearings and brake shoes.

Oh yeah, the iX hubs have different offset than the RWD rear hubs.
