I think you will find all the information you need in this link: http://www.318ti.org/forum/showthrea...t=12852&page=6

Please note that you should NOT use the e34 m5 3.6 rear caliper with stock brakes up front, since it will ruin the brake bias (maiking the 323ti too rear biased). The e34 m5 3.6 rear caliper bolts stright on the 323ti carrier.

I use it with AP-Racing 330x28mm vented vaned floating rotor up front. Combining the AP-Racing with the e34 m5 3.6 rear caliper maintains stock 323ti brake bias. Using only the AP-Racing kit up front and the stock 323ti rear caliper makes the 323ti too front biased.

I got the point about bias. I'm finishing my front brake upgrade ( Big brake kit from UUC).

amazing looking ti, i really love it in BRG.

I gladly take those wheels of your hands if your changing them up They're my dream wheels.

Interesting! Which kit have you selected? What are the caliper piston sizes? Not easy to find info regarding piston sizes on UUC's pages.

I have also modified a brake master cylinder from an e36 m3, waiting to be installed (needed to make m12 of an m10 hole). The stock 323ti has master cylinder diameters of 23.81mm while the e36 m3 has 25.4mm. I do not expect large changes - maby a bit decreased pedal travel and hopefully a bit firmer pedal. I like to experiment and gain knowledge.

your ti is right on so many levels, and those black rims with the yellow stripe are very rare I would assume, good buy

[Grimesy89]

Niiice. Got to be one of the nicest Ti's ive seen. Looks nice in the green. Wish i could get the 323ti over here!!

Well,

E46M3 front slotted rotors 325X28, Wilwood superlite calipers 120-8465 - Bore size - 1.62” 41,1 mm Disc width - 1.10” 27,9 mm
SS Brake lines and pads from performance friction brakes ( race ready )
Also, wilwood exp racing brake fluid.

Let's see how my brake pedal will feel after install. But I'll start to search for rear calipers from M5

I can see why you would like to have the m5 rear calipers. Using the Willwood front and stock 323ti rear would make the bias 77.5%, which I think is far too much front bias.

Using the Willwood front and the e34 m5 3.6 rear caliper would make the bias 73.4%, which is only a bit more front bias than the stock setup (72.6%).

Please share your experience when you have tried it.

Hey,

Tried to install my wilwood front brake it, but right now i'm having some problems. My wheel doesn't fit. So, I need spacers, and ask a professional shop to do one ( 2, of course!)
As my car is lowered with H&R race, i'm a little worried about rubbing issue. Let's see what will come.

By the way, i would like to ask you some more info about rear calipers:

From 3.6 M5, they're plug and play? From 3.8 will fit too?
Will need something more than calipers and pads? Brackets or something more?
3.6 M5 are made from wich year and until?

Best Regards

Usually the BBK advertisers say that minimum 17" rims are required. In my experience one also need to take the design of the rim into consideration. For example AP-Racing and StopTech strongly recommend to printout their template and try it before ordering.

I am using 15mm spacers with my 18" BMW Radial Styling 32, and a bit more camber. However I have several 17" rims that fit without spacers.

The callipers from the e34 m5 3.8 will NOT fit. They are for vented disks. You should go for the e34 m5 3.6 callipers (up til 10/89), since they are for solid disks. They are also used by the e34 525i and some other models (check the ETK, and use the part used feature). They bolt straight onto your 323ti stock carrier. You can use the same pads as you are using today. I usually order rear track pads as for an e36 m3.

Great. Thank you very much, very helpfull!

I found rear calipers on Canada, from a guy that is parting out an E34 1989 M5. He ask me me I'll need brackets too.

About wheels, i'm using BMW 18" 32 styling too. My car is lowered with H&R race, what means that my front fenders are digging the wheels. I'm a little worried if I'll have some rubbing issues with spacers.

What is the offset (et) of your front wheels? Mine are 31

Mine are ET47 for the front wheels (original e46). A 15mm spacer then makes it ET32. I will try a 12mm spacer this year, which makes it ET35, which should be pretty perfect. It seems like the Willwood requires some more space then the AP-Racing callipers.

How large a spacer do you need?

Here is a picture with the wheels and brakes on my previous 323ti:

[Alexandre VTS]

It seems that i need to move my wheels 10cm to clear wilwood calipers

[Alexandre VTS]

Well,

Tryed yesterday to make it fit. I'll need 20mm spacers. Man, that's too much. With H&R race, wheels/tires will stay too close to fenders.
I need new wheels. Does anyone knows wich one should clear? I'll do a thread about it.

[ianik]

I currently run AP brakes front on my 323ti ( 330x28 ). They fit well behind my BBS RX 8x17, no spacer.

I also have a set of BBS RX 8x18, and of course they fit also good , no spacer, with an extra centimeter of clearance.

>>>e36 323ti :I have to speak about rear brakes with you as i have a project for them.
