Exactly. Toyota has even made parts for Land Rover before. I know on the LR3/4 they had all Denso engine electrical systems as well as several sub systems. I assume the new ones are the same. You can bypass a lot of systems on a modern Land Rover. The only things I can think of electrically that would completely disable a modern LR would be some kind of engine management issue. Every other system has a work around. Or you would have the same issue on another vehicle.

Not sure what all the complaints are, apparently the new Defender design is absolutely perfect:

WHEEL MUST BE WHITE STEEL that should be the only option!

Genuinely curious:
You can only get the 18' steel wheels on models below the P400; the P400 has much larger brakes and thus requires the 19' wheel. That got me thinking, are there other driveline differences between the P300 and P400? For example, does the P400 have thicker axles like an HD pack LR3? Personally, I love speed and acknowledge that the P400 is likely the superior powertrain, but is it worth the extra $12,000? For me at least, the P300 is sufficient. However, if that $12,000 comes with a beefed up drivetrain (axles, diffs, CVs, etc...), then it may just be worth it to upgrade. Ultimately, if I wind up getting a new Defender, I doubt it'd be stock for very long.

That's been on-going for YEARS on the Lexus / Toyota GX's.....

Is this for sure? I only see one brake rotor size listed anywhere I've looked. I assumed the 18" wheel option was purely due to options (no "lower end" wheel on a higher option car)
Also, does the HD LR3 have thicker axles? I do not see a difference when shopping axles for HD package vs not. My truck is an HD pack and can measure the shaft diameter - I'd guess it's identical.

It's a good question - they all have the same towing capacity per the website, which is typically the determining factor for brake size unless they are aiming for better braking performance....

I'd suspect (suspect only, I work in aerospace test not trucks) that the SAE J2807 test is typically limited by engine cooling, not brake capacity. That being said, the P400 could very well have larger brakes, but I haven't seen any proof of this. I certainly hope you can run an 18" wheel in the P400 and would surprised if LR didn't allow this on their flagship offroader.

Brakes are different, per the brochure the fronts are 349 mm (twin piston) on the P300 and 363 mm dia. (4 piston) on the P400, while the rears are 325 and 350 mm dia. single piston, respectively. That's over 1/2" larger out front and a whole inch in the back, which makes me think the factory 18s are definitely too small for the larger engine. Hoping and praying the Compomotive PD1880 18" off my LR4 might work on the P400... But I am not too hopeful. I checked and the fronts of the LR4 are a few mm. smaller.
