i was hoping someone knew what size 9 inch rearend will go into the back of our fcs, i took mine out cuz im going all motor and want a different rearend

 

u planning on going solid axles ?

if you want to keep the IRS then the cobra 8.8 / corvette dana will be a better choice, given all these option u'll have to make custom mount / axle.

 

Considering that the FC has an independent rear suspension, you will need to fabricate mounts to install any type of solid axle or custom diff. In that case, you can make nearly anything fit...

 

Cobra rear. Andrewb70 on v8rx7forum is the only person I know of that makes a custom cradle to use it and still keep your IRS.

 

If you have to ask a question like this, you do not have the technical prowess to complete the fabrication work.

And what kind of "all motor" would warrant such a stout differential? If you mean NA 2 rotor, a TII driveline is all you would need.

 

None.

I've learned to just not question the motives behind some of the questions on this board. If they end up overkilling their project its their own fault for not doing the proper research or asking the right question.

Na or turbo, simply creating a new cradle with proper bracing will eliminate much of the wheel hop that the stock subframe has.

 

its a pport motor, i need big gears to launch well. and want better then 5.13s. i didnt now if i could just grap 1 out of the junkyard and if so what yr car, i heard caddilac rearends, but didnt know what yr and also what yr ford

 

Hmm, are you going to run under 9's? Cause those crazy *** guys in Florida are running in the 10's with stock diffs.

 

well to run with the big boys i have to get some big gears, i havea friend thats running close to 6:00 gears
