kiwi328i 118 Report post Posted May 7, 2015 I have the original 530i rear brakes Wanting to go from 300x10 to 300x20. Clean swap. Want to do this before looking at bigger front brakes. I have already got the 540i front brakes etc. Just need/want rears. I think E32 740i/750i is the same? Cheers Quote Share this post Link to post Share on other sites
richard.pykett 36 Report post Posted May 8, 2015 Hi Lionel Are the rears from an E39 540 of any use here? Nice alloy caliper and the rears I think are 298x20 ish... Cheers Richard Quote Share this post Link to post Share on other sites

Is this correct, heck if anyone knows its gonna be you! Cheers Quote Share this post Link to post Share on other sites

(oh and Brent if you see this yep vented 540 on wagon) So again from E34.net its either: Bmw Model Rotor size Rotor part# Caliper part# L/R Clip part# Carrier E34 540i V 300 x 20 34 21 1 159 659 34 21 1 160 399/400 34 21 1 157 046 34 11 1 160 384 E32 740i/il E32 750i/il from 1/90 V 300 x 20 34 21 1 162 967 does not fit 34 21 1 160 399/400 34 21 1 157 046 34 11 1 160 384 I am guessing the rotor hat height is too different, but the calipers, carriers are the same.
