Can you put a set of 4/09 gears in the manual yet?

Thinking of buying the new mustang gt in manual and it would maybe have the 3.55 gears

Can you a gear swap yet with the 4.09 gears in a car with 3.55? Thank you

I'm curious about this as well. From what I've read it's a fantastic upgrade on the 6th gen cars.

I don't know the answer to that but if you can drift a car, you probably don't need a steeper ratio. When you race, the object is to keep the wheels glued to the ground as you get less grip when the wheels spin. Now if you want to drift the car, that could be a good upgrade.

Got the 3.73 PP.
Swapped out the 275/40 19s for 285/35 19 squared.

With the stock taller tires, effective ratio is 3.63

Effective ratio is now 3.74, it m feels nicer and picks up speeder easier.

I do wonder if 4.09 will break traction a lot though.

Steeda has 4.09s in their S650 drag car currently, so it’s been done.

Thanks for the info!

C’mon Ford. Let us at least be able to do a gear change, especially with this terribly long transmission gearing.

From what I have heard a gear change would require tuning. The power packs Ford sells for the S550 mention that they allow you to make gear changes. Not sure how Steeda made gear changes work in a S650 without tuning. Would love to know @SteedaTech
