rear end gears on 01 cobra?

Stock is 3.27.

gears

Make sure your buddy knows you have the IRS not the standard solid axle. Doing gears in your car will take longer and be more work than a standard Mustang.

Since you have the heavy vert I would go 4.30 or if you want 4.10s at the very least. Doing 3.73s on a 4V would not be worth it, our cars have piss poor low end torque and need more gear than the 2V guys do.

I strongly recommend getting this: http://www.billetflow.com/irs_brace.htm at the same time since you will have to have the cover off anyway to do the gears. I have one on my car and it's cheap insurance as well as a very well made product.

If you want to go with 4.30's, I've got a set with only about 1000 miles on them that I'd take $100. plus shipping for. I put them in my 03 cobra but with them, traction was non-existant. With my 6spd, I could run 80 at only 2850 RPM. Let me know if you're interested.

4.30's don't waste your time with the 4.10's.
