Hello,
My friend just got a 03 cobra with 4:10's(wow it pulls)...... What is the stock gear ratio??????
3:45 ??? I want to go 3:73. The 4:10 are too high for me.

Thanks

Just my .02 cents. The 4.10's aren't too high for you unless you like to race to 180 MPH.

Stock ratio is 3.55

Your car will pull much much harder with 410's, and you'll barely notice a difference in RPMs for the mileage. IMO 3.55's = "no mans land"/"the bland middle" for these cars. It's too low for a SC car and at the top limit for a turbo car.
