CX-90 Premium Towing Experiences?

[MadManMotors]

Hi everyone -

I've been following the CX-90 with interest given it's been the first Mazda SUV that seems to have enough towing capacity to haul a race car. I'm figuring a 1550 lb trailer and a 2525 lb race car gives me some overhead for extra wheels, tools, jacks, etc.

Does anyone have any experience towing with the CX-90 with a brake controller and a ~4500lb load?

Hello. I have test towed the cx90 with approx 4200lb over a 24 hour period - the car itself was perfectly behaved and more. However on return of the vehicle, I was told the Mazda cx90 only has a tow ball down weight of 330lbs (I should have checked myself - unfortunately just made an assumption). Using the 10% rule this is well below 420lbs which is a real concern for me. I was also told there were no upgrades available which is disappointing. I have seen the review where the car is towing the race car with a down weight over 330lbs so I'm not sure how that was managed at all?
