Brakes retrofit for e70
 

Would it be possible to retrofit brake calibers from new M3 or M2 ( 4 piston brembo calipers front and 2 piston rear brembo caliper ) on to the 08 x5 4.8i without ton of machine work ? Your feedback appreciated. Thank you.

Why, when the X5 M front calipers retrofit nicely (see signature). You'd have to fabricate a custom mounting bracket, and do all the calculations for piston sizing etc to see if the brake bias is affected.

blue_dragon - i can't find used x5m front calipers at decent price $$$ so far. will keep looking. Thx you for the feedback !

QQ - When I install x5m front calipers on 08 x5 do you i need to change brakes lines and dust shield ? Thank you in advance.

Yes, I chose to run the stoptech lines, and you will need a new dust shield.

Do you think i can use this kit on my 08 4.8 x5 with x5m calipers - BMW E70 X5 M S63 4.4L Braking Lines - 002565ecs02a - Exact-Fit Stainless Steel Brake Lines - Front - ES#2594637

^ What did ECS say?

Lol, good point.

So what did you do to address brake bias? Does the X5M use the same rear brakes as a regular 4.8? Same master cylinder and proportioning valve?
