12 bolt w/33 splines or 9in rearend with g-link
 

Which one should I buy if I am buying a brand new rearend? AND WHY

The cost is only a difference of like $150 and I had had mixed opinions...
My camaro will be pushing around 450-500hp

12 bolt all the way. It also takes less power to turn.

I am in the exact same boat as you. Going with a Moser 12-bolt.

I went with the Moser 12 bolt with 33 spline axles. Here's pictures after we welded the brackets on. it has since been painted.

That looks sweet Chris, same is what I'm going with. What width did you go with what are your wheel specs?

33 splines for 450-500hp is more than plenty. I have a 12 bolt but I don't think it's an earth shattering decision. I've been happy with my true trac so far.

My wheels are 18x11.5 with 5.4" backspacing. My rearend width from axle flange to axle flange was 54".

I set my wheels and tires under the car and dropped a plumb bob from the 12 o'clock position on the wheel lip then set the outside edge of the tire 1/2" from the string. I have plenty of room on the backside...maybe 3/4"-1". I also trimmed the lips down to 5/8" wide for extra tire clearance. I may could have went 1/4" to 1/2" wider on the rear end, but everything seems to look dead on after mocking it up. I hope to have it on the ground next weekend (for the first time in 2-1/2 years), so I'll study it better then.

Remember, you can always add a small spacer, but it's a pain to cut the rear end again. Measure 50 times, then call Frank!

Good to know. I was hesitant about the limited slip at first.

If your not set on changing the gears out, go with the 12 bolt.

It's predictable in a racing enviroment. You'll be happy with it.
