These are 380mm steel front discs (std is usually 365mm) - about as big as you can go with 19" wheels.
They replace the original discs (retaining the standard calipers) for improved braking power plus all the other benefits that floating discs offer, including reducing the likelihood of warping.
Very little wear (as can be seen from the pics) and measure at 36mm thickness. Includes the longer caliper bolts/spacers to accommodate the bigger discs.
Removed from an R8, due to different wheels fitted with a different offset - these bells have an integrated spacer that effectively spaces the wheels out by 10mm.
To fit on a B7 RS4:
Re-use existing OEM bells, and just swap over the rotors.
To fit on an R8 Gen 1:
Just bolt on! The bells space the wheels out 10mm (over OEM), which is the amount many use with OEM wheels to better fill the arches.
To fit on a C5 RS6 (or any other car with the same Brembo 8-piston calipers):
You can get suitable bells machined by Reyland Motorsport for around £250 a pair, then just attach the rotors to these bells.
**Asking just £400 plus postage / collection from Hampshire**
