My 2020 GT500 finally reached the finish line!

[Stage_3]

LOL @kilobravo
You have the BEST avatars when it come to these GT500 threads. Love it.

Congrats @Epiphany ! Drive it in good health. Looks great

Certainly. It'll likely fall between -1.125 and -1.250 with toe set to 1/16" to 1/8" toe in. All up front, likely to leave rear settings stock to start.

Stage 3: Glad you're enjoying them, that's the eye deer. :-)

E: MANY thanks.

Are the Caliper Mount holes the same between the 500 and 350? For example could you mount the 350 caliper to the 500 Spindle?

The caliper bolt hole centers have not changed, therefore the corresponding knuckle to caliper centers are the same as well. Yes, you could mount the 350 caliper to the spindle - careful, that's all you asked, as there are other considerations that need attention.

I would be interested in changing rotors and bolting the 500 caliper to the 350.

You are also going to need to change to the '20 GT350/500 knuckle as well. I show some of this in the following video...

Hmm interesting, Wouldnt this mean that the 2020 Gt350 Caliper would have to be different as well?

 

[Epiphany]

In which way? Remember, I said you only asked the one question. I could have flowcharted a response into a handful of different directions.

In simple terms, while either caliper fits either knuckle, all would seem well until you try rotor fitment. A GT350 caliper (for example) would be in the same space as that of the GT500 on a GT500 knuckle. One issue would be that it wouldn't blend with the thicker GT500 rotor. A GT500 caliper could be used on a GT350 knuckle but you'd need a thicker rotor than that of the GT350 while being the same diameter as the GT350. Pad surface area compatibility starts getting screwy as well.

If I had a GT350 and was hellbent on using GT500 calipers/rotors I'd also pick up the new knuckle and get it done. If I was into hardcore drag racing with the GT500 and wanted smaller front brakes I'd...........**** that. I cringe at the though of going backwards.

Wouldnt this mean that the 2020 Gt350 Caliper would have to be different as well?

We know the GT350 still uses 19" rolling stock. That defines the maximum amount of radial caliper clearance. In essence, it must be the same as 2015-2019. The rotors are the same diameter as previous, just not cross drilled. I believe but have yet to verify that the 2020 GT350 calipers are unchanged. That would mean that it uses a knuckle with revised geometry but with the old style caliper mount locations. Just speculating - I need to verify if there are indeed two new knuckles. If there aren't, Ford made a change to the 2020 GT350 caliper body. Btown, you out there?

Can you tell if an 18" wheel will fit the rear, and know what offset/BS is needed?

 

[Epiphany]

I've yet to see any of the hardware out back.

I guess it's time to reveal my master plan behind the original Question.

I actually want to swap the 350 Calipers onto the 500 and use Carbon Rotors.

Here is the Weight Below-
500 Caliper- 15.6 lbs
500 Rotor- 42 lbs
x2 115.2 Lbs Total


350 Caliper- 11lbs
350 Carbon rotor- 15lbs
x2 52 lbs total

63 lbs total Weight loss

Very nice way to loose a decent amount of weight. I hope the loss in braking power doesn't hurt in other areas of tracking.

I have zero clue, I have no experience in this field.

Interesting. What I'm not aware of is master cylinder bore size on the GT500. If you plan on changing that (if necessary) then disregard.

I'll have to see what the 2020 GT350 is using, that differs from 2015-2019 GT350's. I'm beginning to think it simply uses its own knuckle, differing from the GT500 version via shorter caliper ears - or not. I may have missed something so I'll go back and look at this again.

Thank you sir for the video, as far as I am concerned, it is clear, not only do you have to do the knuckle, you also have to swap up to 20" wheels.

you make that happen and id be very interested in doing the same, for different reasons
