F8X Brembo BBK Swap on E46 M3

[phoenx]

Waiting for someone to install CCB's onto their E46 M3 from the F8x platform. Makes no sense because you'll be able to only run a select set of 19s, but damn that would look good.

Funny enough, the ceramics on my f80 will be coming off in the summer and it wouldnt be a bad idea to throw them on my e46! Only thing that would hold me back are having to use very specific set of 19's because not all 19's clear these brakes.

Any concerns with either the now non-existent dust shields in the rear or added unsprung weight?

Hey Johnvu, I wanted to thank you for your very detailed very precise orientation on how to do this conversion. I was able to follow your step by step and install mines. And btw, for all those out there wondering if you can fit this on 18 wheels…yes it is possible, here are some pics.

Awesome! Glad my write up was helpful!

No Sir, shaved the mounting points on the front ones as per your instructions and the rears just bolt on with the adapters…and middle of caliper shaved to allow the adapter bolt to fit…and that’s it!

No spacer?

For those thinking F80 fronts are a little too big, FreakyParts over in the UK sells a front kit that puts a Renault Megane Brembo caliper (same as the buildjournal) on a e90 front rotor. It’s 360 x 30. So 15mm larger diameter and 2mm thicker than ZCP. I installed this on my car last month and am very happy so far, will try it out on the track this spring. I have the 996 setup on the rear.

Where did you get the brake lines?

Casual bump for brake line vendor

Thanks PHX, would doing f80 front and rear be too rear biased for mk60?

Can’t say honestly. As far as I know whoever has done the swap hasn’t had any issues. My ABS and even traction control, when I forget to turn it off, work perfectly well.

Do you track? I'm curious to see how these hold up and how the brake bias is. Anyone else track with this conversion and can chime in?

I do track and had the Porsche BBK prior to this one and I wanted a little more front bias. Now I’m on f80 fronts and 996 rears and I find the balance perfect.

I'm Using F80 Fronts with 18s and they have a good amount of barrel clearance. Face clearance depends on the wheel.

Yes but just make sure you get measurements for whatever wheels you are buying. I ended up going 19" Te37's because I didn't think 18's would fit and I didn't want to attempt to fit them. I think most 3 piece 18" wheels wont fit since the face tends to be a smaller size and the barrels require a step making the inside diameter a lot smaller.

18” TE37s clear and 18” Apex FL5s clear as well. You can go to the m3/m4 forums and look at what 18s clear.
