4.10's and what else?
 

I've got an 03 GT with an automatic tranny. I'm swapping 4.10's this winter. What other mods are reasonably priced and will get me closer to my goal of a 12 second timeslip? thanks

Things like cold air intake, exhaust, nitrous :D. You need to check out the j-mod here it's in chapters 13-14.

12's? Easy...

Gear, exhaust, tune, and a 150 shot.

On street tires, you'll run in the high 12's. ET streets, or ET Radials, you'll be in the high 11's super low 12's.

Thanks guys. What brands of parts are popular for this car?

With those gears, get a 2500 stall and either the j-mod or a valve body for the trans. Both with help you get the most out of those gears.

With 4.10s and a good stall converter you'll need some sticky tires to make traction. Those 3 things will really transform the car and it will get up and go from a stop.
