E46 Budget Big Brake Kit (F30 Brembo)

Описание: Hello guys this video is just going to cover how I did my budget big brake kit on my e46 v8 project for under £500.I noticed I didn’t have the budget to get csl rotors which are 345mm and I didn’t want to have to compromise the brake pad surface by using the stock M3 rotors which are 325mm so this is what I decided instead.

Costs are a big factor as always so this is the breakdown;
discs (340mm) £85 new
full set of 4 callipers (340mm) £300+£20pp but only used the fronts and sold the rears so spent £150
spacers (or washers) £3
Stud set conversion £25
TOTAL= £263+ Tlc hours ;)

So after doing some research from forums and other videos the brakes which were a direct bolt on were the 340mm brakes from the f30 which are standard on some M sport BMWs from the E9x generation
F30 brake callipers from performance spec car (M car)
Part numbers are as following for the callipers;
Left calliper-
BMW - OE-34 10 6 855 476
BMW - OE-34 10 6 855 478
BMW - OE-34 10 6 855 480
BMW - OE-34 11 6 799 466
BMW - OE-34 11 6 850 932
BMW - OE-34 11 6 865 538

Right calliper-
BMW - OE-34 10 6 855 475
BMW - OE-34 10 6 855 477
BMW - OE-34 10 6 855 479
BMW - OE-34 11 6 799 465
BMW - OE-34 11 6 850 931
BMW - OE-34 11 6 865 537

I used the 340mm brake discs from a t5 transporter van as they have the same bolt pattern which is 5x120 and are the closest to the original rotor on the f30 with a smaller hat height to match the e46 hub. (link below to ebay where i sourced my discs)

If you have a bigger wheel hub size then you’d have to get the centre hub rebored to 79mm as the discs come with the 76mm diameter and the top hat is slightly different so you’d have to have an offset of -3mm

You’d also need a washer to space the brake from calliper which is;
0.9mm for the standard e46
6.44mm for the M3 and Z4

Also note that only certain 18" wheels will accommodate the set up unless you go up a size to 19s or have wheel spacers to create an offset.

I will update this for the future if this also fits for e30-36 hubs if i get a chance to try it. Again thank you for watching. Subscribe for more content like this.
