2020 Supra Rake Angle

[DrMaryStone]

So after trying to unFK my suspension issues the shop I am going to now noticed that the front of my car is actually 1 inch higher than my rear. This would be negative rake correct?

I tried doing some research on rake angles for this car and didn't find a whole lot. What would be a general rule of thumb to go by for a positive rake angle?

Right now it would appear we are introducing some unnecessary drag coefficient with the front being higher. My understanding is that a positive rake would allow the air coming into the front to expand into a larger volume of space at the rear. By doing so as the air travels from front to rear the pressure drops which sucks the car into the road.

I'm not even sure if any of this really matters when considering we are working with a 60k vehicle. Still I would like to hear everyones opinion on this and if there is an optimal angle I would like to know.

Thank you,

Not sure on rake but I can give you OEM height measurements so at least you have a baseline:

Measured from center of wheel to fender, 14.5" front and rear

Yes, rake is usually front lower than rear.. My 2020 is on stock suspension and has some rake as she should.

Negative rake is usually referred to as the 'boat look'.. and not very practical for performance oriented cars as it's too rear heavy.. unless I suppose some drag cars..(?)

Would you happen to know your height differential?

also, ride height straight from the service manual:

OEM body to ground and ride height numbers I measured when my car was stock:

Thanks buddy. I'm wondering if I should put a positive rake on the car however or just have the height differential stay 0 as I am seeing your photo.

OEM has slight forward rake (Front lower than rear) and I added a little more with my setup as I have a front splitter.

Also the Supra GT4 has a good amount of forward rake as well:

By slight are we talking 1-2 inches?

I always felt the Supra looks too high up front(negative rake) on stock suspension, even if it isn't but after a 1.2 inch drop all around I can see the positive rake plus I can see the road better through the windshield.

Probably way less, that is significant
