Bigger brakes

All of my HP2 D2s brake better than my Brembo D2s

Pretty simple really. The adapter is just a piece of 10mm flat bar with four holes in it. Wheel clearance is an issue as the caliper is quite chunky and the disc is quite flat compared to the D2 stock disc offset. I can't remember if 18" Avus clear, but the 20" FE wheels need spacers. ET needs to be 30-35 I think.

They stop very well but these discs are very prone to warping and judder and, at £1000 a set, that can get expensive very quickly! This particular car is going to get updated to C5 RS6 discs which are non-floating 2-piece and which are both cheaper and more reliable, at a small weight penalty. They also have more disc offset so we can move the caliper inboard to make more room for wheels.

The brakes on my B7 RS4 are a real bug-bear, they are just seemingly high maintenence and bloody expensive as no real aftermarket parts.

They do stop, but I'd personally look at other options unless you want to create a new headache for an 8

Thanks again MikkiJayne but now I'm confused. How is the flat bar mounted as there is no way it will mount flat to the upright as see in this picture Or is the opposite side of the upright flat that's not visible in this picture?

Your picture is from different car. Flat bar was on S8 with Brembo brakes. Different brakes and uprights on S8 compared to A8

Correct ^

The RS4 setup is on an S8 Brembo upright whereas I am showing the Porsche 18z with the A8 HP2 upright.

Thanks for the clarification as that makes more sense.
