Hi, looking forward to someone that has installed and coded successfully the car with the m sport brakes.

I have a 120i LCI with b48b20A, and I'm about to install the m sport brakes front a wrecked m235i. I already have the 340 mm front rotor with 4 piston blue calipers, and 345mm rear rotors with the single piston blue calipers.

PD: If I found something I will be posting it here..

Hi!

Any progress with retrofit? I will soon have to replace disks and I am looking for option to replace everything with M sport brakes.

Hey, yes I already completed the retrofit 8 months ago.
I put:
- Front 4 piston blue calipers pair with a 345mm rotor and akebono pads OE spec.
- Rear 2 pistons blue calipers Pais with 345mm rotor and 160 mm parking brake ( there is one with 180mm that won't work) and same akebono pads
- Replace the master cylinder from the bigger and bifer one from Fx35/Fx40, there are not the same.
- Coding via e-sys, I enabled the SBPR ( m performance brake) and car has worked like a Sharm, no smushy feeling. I'll post pics in a bit.

Yes, the master cylinder had everything already. That was like $80 used.

It does, you need to be carefulñ when picking the rotors, since there are 2 sizes.
I did not change the parking brake

Also, forgot to mention, I replace the dust shield, front and back. Had to cut the rear ones because there is no way it can be changed without removing the wheel hub.

so you only cut the rear ones and didn't replace them, I'll do the same too

I will install Hel braided hoses, brembo pads p06087 and p06088, and discs zimmermann 150.2903.20 for front and 150.2921.20 for read.
