DIY: B7 RS4 Front Brake Swap to B6/B7 S4 Full Write Up

[OneFastBMW]

I understand the drawbacks of the 380mm kit, I just think it looks so mean though. They are for show than additional go (or stop in this case).

I have wheels that really draw attention to the brakes (HRE 545r's) so I felt the stock brakes weren't up to the task. I have a surprise coming for the back brakes early next week.

I don't mean those giant ones...I mean the OEM sized, JHM LW RS4 rotors. Where'd those go? they used to have them.

I will just need to buy some pads and RS6 pads (which can be found cheaper) fit to.

what are these selling for in the aftermarket?

what is the approximate cost of the other parts required?

thanks

A little something to add to this write-up I read about that may enhance this or any other brake set-up.

VW Phaeton

3D0 615 447E - cooling duct left =£6.23+vat
3D0 615 448E - cooling duct right =£6.23+vat

3D0 615 311C - splash shield left =£15.98+vat
3D0 615 312C - splash shield right =£15.98+vat

You also need 10 allen head bolts M6 x 8mm part no. N 102 849 02



Done on a B5 S4




All that was required was to cut some of the lower part of the plate away, bash some of the upper part and open out the bolt holes slightly.

I'd like to know how this RS4 setup compares to the cayenne caliper BBKs. Whats the weight on the RS4 calipers?

A little late but I was able to weigh my RS4 calipers yesterday.. They are 14.7lbs each with pads.

[drumnjuny]

is this dead or did you do the Rear swap also? damn i would kill for a set of RS4 F&R brakes

[AUDIA8MAN]

I did this mod and love it! for the rear I bought the s4 kit since I have a a4 b7 ,works well with hps hawk pads in the rear,firm grip to match the front, and when I track it's dtc-60 hawk in the front .

any tries with different wheels? I have the oem sline 18'' on with 12mm spacers to barely fit. works great but would love to get the vmr v710 18''-8,5''-35offset to fit. any clues?

thx!

I needed a 3mm spacer to clear on the 710's

makes me wonder if my rs5 brakes will fit on my b6 with 380mm rotors before i locate some nice two piece rims.

Based on my search, the caliper are the same. But the offset of the rotor on rs5 is different from rs4. You may need a custom bracket. Apikol may have one. Or you need some custom setup for the rotor.

Coming from 2025. Just question if the abs module needs to be coded to rs4?
