DIY Brembo BBK

[X53Jay4.8is]

Okay so a few more details of whats being used for the transformation. The front calipers are Range Rover Sport 6 piston brembos. The front rotors are 380mm Range Rover Sport. They carry the same center bore and lug pattern as the E53 X5. I will have more info once I get a few adjustments to the caliper mounts. I promise to include all that it takes to make it happen.

Interesting! I thought you were going to be installing the E53-specific kit.

Will this conversion be more cost effective than the kit considering these are late model Range Rover parts?

And have you looked into how compatible these calipers are with the stock brake master cylinder?

Very nice. I found 2010-2013 ones on eBay but none for 2013 and above. I look forward to seeing your progress

For us 4.6is guys our fronts are 356mm if I recall correctly. Do you see a need for an upgrade from 24mm or is this more for the calipers that show braking improvement from a 2 piston to a 6 piston setup?

No braking improvement noticable on the streets.....but it sure looks good. Even at 13 yrs old, the 8 piston F /4 Rear always has passerbys coming up for conversations, and at red lights, etc - thumbs up, etc.

Just be weary about your consumables costs as well.....

Two X5 members have done this upgrade in Europe and it works without problems. No need to change the master cylinder.

From those that have performed the upgrade have noticed an improvement in braking. I dont track my X5 so I would imagine that I am not going to see a huge improvement. I'll need to weigh the components but right off the bat the 6 piston brembos are lighter than my 4.6is calipers. The rotors that I spec'ed are about the same in weight to my OE rotors. So once I have all the components I'll weigh them and provide the info. The real reason that I am doing this upgrade is because I want a big brake kit and came across a great price on the calipers.

Yes those rotors for the X5 E53 Brembo kit are very expensive.This is one reason why I went with the Range Rover Sport 380mm factory rotor. Cuts cost substantially.
