e90 Springs on e82?

[white08135i]

Ive seen a few people selling lowering springs of a 135 stating they fit an e90 and vice versa.? I know most of the suspension parts are interchangeable, but i wasnt aware that springs are the same?

Will the springs off a e90 actualy work on a e82?

Springs are the same, meaning they fit but... different spring rates depending on a few factors.

+1. And it also depends on the car's options which spring rates are best. That's why the Performance springs vary in part number depending on your car's build.

I talked with Harold from HPA and he explained me the springs were not the same

thanks guys.

e9x springs in general fit, but here is what I have discovered by handling 135i and 335iS springs:

e92 vs e90 - Front Springs are the same based on Engine and transmission differences ( 335i share same springs for front as 135i for MANUAL only, 328i manual and 128i AUTO same thing - 128i would be softer springs for manual)
- the rear springs are taller for e90 - see Swift R springs thread in e90post - the sedans seem slammed on e92 springs

e92 vs e82 - OEM rear springs are beefier for e92 by less than a mm in diameter of coil. Therefore its possible they will not lower to e82 135i level when used

335i/ 135i front springs will raise the front of a 328i /128i - using SP lowerign perches will lower the extra rise back to OEM sport 128i/328i setting

335i/135i springs should in theory work the same( lowering height) for e92 OR e82- BUT keeping in mind the spring rates THE 135i stand to benefit more. I dont think 335i should use 135i springs, a 328i e92 could get away with it

Convertable e88 can probbaly use e92 springs and have no issues

So do you think i can use e90 335i lowering springs on e82 135i?

if its e92 spec sure, not e90 spec cuz of rear. But e92 rear springs may have less drop cuz e92 is heavier in the back

the front resulting height should be in theory the same as e92 because both 135i/335i have used OEM labelled "D6" springs.

If you fear a bad result, use SP lowering perches

Random thought: The e90 is heavier than the e82 so doesn't that effect how low the car goes and stuff?

for the front no, the engine/trans is the weight hence why D6 is found in MANUAL 135 and 335i and prob Auto/DCT 135i

Rear - e90 stock sport spring is longer than e92 sport
e92 sport vs 135i rear are about the same physical length, with 335i shorter but with thicker coils by less than 1mm( i checked). Chances are you could get away with it on a 135i/128i if you really want to. The result will be very OEM Msport height.
The question is what is the motivation...

if you get e9x coils Okay. If you want to use e9x springs be careful with the front and avoid e90 spec. if you want to use e82 on e92 its a risk with the rear for i guess because of weight of e92, but an aftermarket spring like H&R should be okay

whats the real weight difference between a 335i (e90, e92) and 135i?

Not sure of the exact weight but I would think the e90 would be heavier since its a 4 door and larger than the e82. I may be wrong

Hi guys, sorry for bringing up such an old thread but it didn't seem right to create a new thread when this one is related to exactly what I'm curious about.

My friend has a set of Bilstein B8 shocks + H&R Sport springs that were on his E90 320i. I am wondering if these will fit in my E82 135i.

Reading the comments above it seems like they will fit in theory but the 320i springs will probably not lower my 135i ride height by any, if at all.. And then there's the handling aspect which may be impacted due to the difference in weight, is this correct?

If anyone could shed any light at all that would be great.

Thanks!

Can't comment on the springs other than saying you should probably wait around for an E82 specific setup if you want predictable lowering and handling. But on the Bilsteins, you can simply check the bilstein part number on the shock and compare to the Bilstein B8 part numbers that are quoted for the E82, if they match then all good just pick a set of springs and you're golden. If not, it's an even bigger crapshoot ....

Not sure how much of a deal you're getting, but keep in mind a new set like the Bilstein B12 which comes with B8s + matched Eibach Pro kit springs is less than $700 brand new.....so may not be that much of a stretch to just get new....

As an aside, what would OEM E92 M3 rear springs do on a 135i as far as ride height goes (with suitable camber arms and spring seats)? I was thinking I could use a little extra rear rate compared to the Swift Spec-Rs I'm running, M3 is 550lb/in compared to the Swift's 500lb/in

Why not buy some TCK or Swift 60mm rear springs with a height adjuster.
