Is the M3 diff superior to the 335i + Quife or wavetrack?

I found the complete rear of m3: diff, half shafts, subframe, rods, wheel carriers, bearings, brakes etc for 1600€ but the sellers doesn't know if it is 3.85 or 3.15 likely 3.85

For me now it is a go - no go situation shall I buy????

I am also wondering if the M3 diff can cope with the extra torque of the 335...
Does anyone know what the M3 diff is rated to?

I think the M3 assembly is stronger than the 335i

but what about the M3 diff compared to quife?

GeorgeSmooth · 11-18-2009, 02:24 PM

The M3 diff should be stronger as its got bigger and beefier components. The question I raise is if it is more reliable as a diff on overall. The quaife in no way makes the OEM diff weaker or less reliable or stronger for that matter.

another question:

Is the wheel hub of M3 the same of 335I ?

On the hub there are the grooves for ABS sensor, as far as I replace the complete rear axle with the M3 one I need to know if the ABS can work whit the M3 hub...

I think you are on your own with that one. Why would you want to use the M3 hub?

marconi118 · 11-19-2009, 03:18 PM

I got a complete rear subframe of M3 including all the suspension, brakes wheel carrier etc... I hope I can do a compete swap

i think he is wondering if the cv axle will fit into the stock 335 hub or not, i was wondering the same thing, cuz isnt the m3 axle thicker

I take it the e92 M3 subframe is a direct bolt-in to the 335?

So then if you were to purchase an m3 driveshaft and support components you could bolt in the m3 rear drivetrain correct?

Thanks,

Bump for an answer-

%%I am not shure it will work but I try.

The subframe of M3 has different part N° but the bushings should have the same points on the frame of the car.

will keep updated if it work

Awesome, thanks-

GeorgeSmooth · 11-20-2009, 01:29 PM

The M3 shaft fitted directly with no modifications that I am aware of. I am going to speak to my tuner who has been unavailable for a while and get every little detail. It happened so fast that the one day he asked me if he should try and the next night he phone me to collect it.

marconi118 · 11-20-2009, 01:37 PM

what I am wondering is exactly what was done on the drive shaft half that is attached to the gearbox

technik330 · 11-20-2009, 01:52 PM

That's what I meant to ask, would an m3 d/s fit into a 335 transmision. If so, I'm sure I can get a carbon d/s made to fit-

The M3 driveshaft cannot bolt onto the 335 transmission. That why I used the two pieces.

marconi118 · 11-28-2009, 05:15 PM

could you please post some pictures of the drive shaft especially where the 2 half join?

Will try get them by tomorrow for you.

marconi118 · 11-28-2009, 06:06 PM

GREAT thanks!

I have the dif, now need to explain to my shop how to assemble the 335I and the M3 half parts of the drive shaft

marconi118 · 11-29-2009, 09:54 AM

another question, who is selling aftermarket Carbon Fiber M3 shafts?

I need one half for the conversion so maybe to go with CF would be a plus

how is the M3 diff compared to quaife or wavetrack? will it lock even if one wheel is off the ground?
Quaife will not
wavetrack will
M3 diff???
