In the process of swapping my e91 from auto AWD to 6sp rwd/n54.

I know the wagons have a higher spring rate in the rear but would there be much difference in 335 vs 328 for weight/valving? Checking specs the 335 e91 has same load ratings as 328 on euro site.

In Canada I only have access to 335 e92/90 or wagon 328.
I cant see the 328wagon being any heavier than 335 sedan

Bilstien hasn't got back to me yet.

Euro site shows same part number for 330i amd 335i e91 so ive answered my own question.

Leaving this incase some one else needs it

lol, doing the same thing right now !

So I'm sold to H&R, and if you look part #, they are different for a e90 335 and E91.

I had KW V1 coilover (for the E90) and didn't want to use them, so I never tried on the E91.

Looking on google, people using E90 h&r on the E91 , makes the car look weird, and had to add spacers.

I just put back the 335 rear subframe on the E91 this weekend, but the car is still on jacks, can't tell if it look weird.

The weight is 1 part of the equation, spring K value should be different for sure, since you can load more into the wagon. Wagon is heavier.

Should clarify. The bilstien part numbers are the same for 335i b12 and 330i e91. The e90 part numbers are different as the rear rates are changed.
