E46 330i brake conversion done!

[byron]

shouldnt the abs prevent any problems from hitting the brakes while cornering?

[M52 POWER!]

ABS just stops the tires from locking up, it'll still spin your ass around

That would be something like yaw/traction control.

whats the bias with the e36 328 stock brakes?

[Captain]

From what i've read, if you put any e46 on the front, it will give you more front bias then you already have now.

e46 330 calipers do not fit the e36 rear without cutting the dust sheild.
e46 328 calipers do fit without a problem and reduce the front bias from stock.

The master cylinder is not needed for this, but it reduces pedal travel with a certain setup.

i think an e46 330 or 328 front with e46 328 rear would give you a near stock bias, just with bigger brakes. Wait for techno to chime in to correct me if i'm wrong.

i am hoping he does. he seems to be the bf.c expert on most things mathematical.

[Captain]

and byron, he also already posted what the stock e36 bias is.

[widebody_bimmer]

ya I agree this upgrade is totally worth it for E36 non M cars...more freeway stopping power and no brake fade ... add some UUC SS brake lines and your in business

[atog]

has anyone figured out the braking bias with e46 front and rear brakes?

[byron]

^^^
not yet i do not think. if i knew how to do the math i would but unfortunately i do not

[techno550]

answers are in this thread. post #21

cliffs notes:
stock bias for E36's (non-M cars): 60.5% front
stock bias for E46's (non-M cars, non-330): 57.9% front

[byron]

would it be safe to assume that if the e46 328 has more rear bias than the e36, that the 330 would also have more rear bias? how much is that going to improve braking?

[M52 POWER!]

I think because the E46 is a heavier car BMW made the bias more in the rear to improve stopping distance.

[widebody_bimmer]

^ makes sense.

[byron]

wouldnt those same brakes then help an e36 stop faster?

[Ahheck01]

bump for this!

[328Limo]

In Europe E36 328i have vented discs at the rear (276X19).

All models not only the Convertible as in US.

What is the BIAS with these brakes?

Maybe race cars have nerly 50% bias f/r because they use wider tires at the rear.
It's logical to have more braking power at front because the weight is transfering forward under hard braking. Is it not?

The E46 330i rear calipers and brackets did fit to my E36. But, I need to modify the parking brake. Does anyone know how to do it? Thanks.

[Hollywood Hamilton]

You will need the 330i parking brake components, i.e. the pads and springs.

[gooten1]

Ok, here's a bit of a change. I upgraded my front brakes on my '97 318ti to those off of a '95 325i. The front bias is nasty. It feels like probably close to 70%.

I know the rear end of the 318ti is different from the regular e36. Are the brakes different? I haven't gotten to look at a stock set up off a 325 (but I see what you've posted re: size and piston diameter). I know my rears are a small, solid rotor with a small caliper.

What set-up should I think about to move the bias further back? In a car as tail-light as the ti, it makes a big difference. Right now, under hard braking it feels like all the weight comes off the back end entirely. The weight transfer is terrible.

[DP10]

Thanks for your advice, Steve. I did try the E46 330i parking pads, but they were too large when I fixed them to the original parking pads positions. Would you mind giving me more detailed instructions or photos? Thank you in advance.

[Hollywood Hamilton]

Yeah, I will try and dig up some pics for you, I did have to dremel the bottom holes on the pads to get them affixed properly.

If we put the E46 330 fronts on with E46 328 rears, we get 61.2% front bias.

this ios the set up i would like to go with myself. i know the fornt is a bolt on swap.is the rear aswell and what do i need to do the rears?
this is for a 1993 325is

Yes same kind of bolt-on deal. You need rotors, calipers and caliper brackets. You can use your old pads, as they are the same size (assumming they are worth using).

Any need to upgrade to the e46 parking brake assembly when swapping to 328 rear rotors/calipers? How about 330?

From what I've read (grain of salt...) the E48 328 rears use the same parking brake shoes as the E36. The E46 330 uses larger parking brakes shoes, and requires some trimming of the dust shields to fit the larger rotors. The parking brake cable and brake fluid lines might also be an issue on the 330 rears, but I have no first hand experience.
