325is brake upgrade?

[Artem]

Hey guys, sorry to bring this one back but I got a relatively specific quesiton.

So I bought a set of rotors all around for my car, and turns out they sent me the vented Brembo ones for the fronts and my car was made in 09/97 - long story short, I got the E46 325i brake caliper + carrier set off an 04 sport and I was wondering the following:

if I have the 286mm x 22mm vented disks, will the E46 brake calipers still work on my car or would I have to get a whole different set of carriers off an E36?


Regards,
Artem

I just checked and according to realoem the E46 325i brake rotors are 300mm x 22mm. That means the carriers you have are spaced out too far and will not work properly with the 286mm rotors. What you should have gotten was an E36 setup or maybe the E46 323i seytup to use those rotors.

The calipers are all the same, all E46 and E36 22mm calipers are the same until you get into the M stuff, it is the carriers that vary the posistion to work with the different diameter rotors.

Either send back or sell the 286's and get some 300s or your going to have to change carrriers.

sorry,
Dave

The E46 carrier and callipers will bolt right up no problem.

Wow, that was quick!

I cross referenced the parts again, and the calipers are identical from the 04 325i; the carriers are not, but the car had 65k miles, calipers looked good, and it was relatively new (only 8 years old), so I think I am happy about those calipers, and will use them when they come in.

Thanks for the clarification, Dave!

On a related note, anyone has a set of E36 (non pre-04/98 TI) brake carriers for sale local in the bay area? Its a huge PITA to get a hold of anyone on CL that has even remotely a chance of selling them.


I decided to go with the stock E36 setup, as I think it will be enough, and I dont really want to wait for them to deliver me new rotors.








Ridiculous shot in the dark but its always in the back of my mind, anyone got a california roof assembly that works for sale?

Can u still run standard 205-15s with the 325 front brake upgrade

[Artem]

I believe if the wheels came on a 325, they can be used. I think the 325's and 328's had an option of running 15x7 wheels, if you can get them, they should fit, as they ran those brakes.

e36 286 mm brake disk= 15 rim
e 46 300 mm brake disk=16 rim
M3 315 or 325 mm = 17 rim
M3 CSL 345 mm brake disk = 18 rim

Do pads from an e30 work in the rear?

[Marry Parker]

Luk Schaffer makes a nice slotted cross drilled rotor (this may help keep them cool and prohibit warping) for not a ton of money. I think they're called Black XD Series. Tell him to make sure that his calipers aren't frozen when installing new pads or rotors, better yet replace them or rebuild them if in doubt. This will help to insure longer life and no rotor warping. I've had mine on a BMW 325i for a year and been happy with them.

I was thinking about getting 4 rotors and calipers off a 325is.
Do you guys know if it's a bolt on upgrade, or do i need to modify a few things?
I know that 2ndBimmer has a 325i brake upgrade on his car.
Is there a difference between 325i and 325is brakes?
I assume that there isn't any, but just wanna make sure.
Finally, do you guys think that the rear brakes will fit onto our cars?
Thanks guys

why didnt i see this thread ages ago i ve been messing about with e34 disks and calipers this week !!



I really like the idea of the 300mm stuff but i have to stop under 15" wheels, can you space the wheel out by say 10-20mm and clear the ridge in the wheel?

thanks

e34 will be good for the rear upgrade - same size rotor i think but bigger caliper. As for the front you can fit m3 e36 front brakes under 16" wheels, you just need some lower offset. From what I understand the 286mm brakes (325/328) vented will work with 15"

i have some 735 calipers and disks ont heir way, i dont know if they fit exactly or what.

i have 286 disks now, i want 300 if i can get them under 15"

I may need to space them out a bit to clear the ridge int he wheel

Well let us know how that works, as far as I understand anything more then 286 will not clear 15" but if you can manage a 300mm under a 15" I would be very interested in finding out what parts you used.

You don't find the 286 with good pads/rotor/brake fluid etc to be good enough stopping power?

[bmw2101]

its a rally car, so its getting some real abuse, we do say 150 miles in a night, ont eh public roads, all legal etc, but last event i foudn i lost brakes, i use ds3000 front and 1155 mintex rears, castrol 600 fluid. my car weighs 1330, but has gone on a diet, its got 180 bhp and 5.0:1 end ratio now with lexus is200 6 speed box. I have to use forrest tyres which best are sp85 dunlops or 035;s yokohama.

I looked into other brakes liek the porche ones but i just craving more!

most is on the tar but some is on the loose which is where ypu easily get punctures.

More of an idea

was out ont his oen but not on the vid...

[slade13]

I just but vented powerstop front rotors and caliper brackets off of another e36 today. The problem that I have is that I had to shave the pads almost in half to get the calipers to fit. What am I missing here? The pads fit all e36's.
