Can Anyone tell me the part number of the db9 4 pot Brembo calipers which are the same as the ttrs mk2/rs3 mk1 ??? I have researched 2 numbers they both look identical does anyone know the difference?
20.8429 and 20.8427
Thanks

No the part number for left and right are as follows
20.8429.03 or 20.8429.04
20.8427.03 or 20.8427.04

just don’t know the difference between the top and bottom codes

Perfect thanks! I believe it’s stamped on the inside

They are the same calipers but you cannot fit them directly on an RS3/TTRS unless you alter the link pipe around. On a DB9 the calipers are trailing on an RS3 TTRS they are leading. If you fit them without reversing the brake fluid connector pipe the pistons won't be correct with the larger piston leading instead of the small one.
