325i and 325ix rear wheel hub differences?

[jute91]

is there some differences between 325i and 325ix rear wheel hubs? because im wondering if i could put real wheel drive hubs and brake disc on my ix, i could use low ET wheels. noticed that ix brake disc has more ''ET'' coming out.

According to realoem.com, the parts #'s are different. BUT the 325i rear hubs are common enough, get one and compare it to the iX hub.

This seems like a decent idea, I highly doubt it will work though.

yes IX hubs are deeper to make up for offset in rim and for track width to match the front due to FWD components on IX front struts. if you try to put rear IX rotors on rear 325i hubs they will hit the backing plate ,i know this for a fact as ive been swapping rear trailing arm components from a 325i onto my IX trying to find track down toe issue ,which is looking like a bent subframe

But when using 325i brake disc with its hub, it wont hit backing plate? cos those brakes disc are different too?

[spdracrm3]

right ,the backing plate and parking brake assemblies are the same and in the same location on both ,just the hub is deeper and consequently drum portion of rotor is deeper on IX. so if you swap to 325i hubs the the 325i rotors will fit perfectly with normal clearances

[jute91]

so, here i come ebay. gonna start looking for BBS RS

[spdracrm3]

so what do you plan to do on the front where you cant change hubs and therefore offset?

you going to run different ET wheel front and back?

[jute91]

im going to count difference within hubs, then pick up wheels that comes out directly same distance. rear 8-9'' wide front 7-8''

That's good to know...

If you need a new subframe I have some
