    What I need to do first?

    So I have a 99 SS with LT headers, custom 3 in. y-pipe no cat, cat back high performance magnaflow ss with 3.5 in. duals. Volant Air intake, slp smooth bellow, and a Pro Form short throw shifter and other visual mods. I have to have the ECU remapped due to no cats and I was going to replace the spark plugs and wires before I have the tune done. But my rear end needs rebuilt as well so im am having them install 3:90 gears. Should I get the rear end rebuilt first then do the tune?

    i wouldn't rebuild a stock rear ever... they are very weak and especially with lower than stock gears...

    save your self the money you'd spend in rebuilds and buy a good 12 bolt or 9"...

    I agree, if you intend to keep the car, put a Moser 9" in it. The $2600 to 2800 cost will pay for itself in the long run.

    matter of opinion i guess. I realize they arent that strong. Lots of people have pushed good #'s with a stock ten bolt. Its the sticky tires that are hard on them, IMO. I keep my fingers and toes crossed when driving hard tho
