Would my 2000 camaro ss have a 12 or 10 bolt rearend?

 

It is a 10 bolt. Just count the bolts that hold the diff cover on.

 

Do you think 4.10's would be a good choice for gears for it or something else?

 

The 10 bolts are weak and going to a steeper gear will make the ring and pinion even weaker. You already have a 3.42 gear (your a 6 speed right?), I would do other mods first.

 

No its and auto.

 

So do you think I should get them o something else?

 

If you have some money, you could buy a performance rear axle. How much power are you planning on putting out. That is another factor. I'm putting out 510 HP and 495 ft/lbs torque. I have chosen to build up my rear 10 bolt rear axle. I put a 3.73:1 in my 8.5" rear end. It was originally a 2.73:1. It has a posi, and new axle main caps. I used Richmond gears. When you start going through gears, that's when I'd make the call to change the axle to a 12 bolt.

 

Do you know a website where i could find that 12 bolt rearend?

 

I'm still looking for one that can just drop right in. All the ones I can find end at the 92 Camaro.

 

Strange and Moser both make 12 bolts and 9 inchs that will bolt right into a 4 th gen. I thought you were a 6 speed for some reason, now that I know your an auto, I would sugest a stall and some other bolt ons. The auto cars are gentler on the rear ends, not saying you won't break it, but there is less of a chance. I am still on my 10 bolt and run 11's with short times in the 1.5-1.6 range.
