Welcome to the Michigan FBody Association website.
The Michigan FBody Association is a centralized website for FBody enthusiasts to discuss what's going on in the Michigan area. MiFbody.com was created to allow for an easy one-stop place to find out what's going on in Michigan as far as FBody events, to find out what clubs are available in your immediate area, and for an easy place to post classifieds for items you want to sell! Our goal was to create a more close-knit community of FBody enthusiasts in the state of Michigan, and to bring Camaro and Firebird enthusiasts alike together for some amazing FBody events!
The most important thing to know about the Michigan FBody Association is that we are NOT a club! The Michigan FBody Association is open to everyone, and is a community. Thus, we will have get togethers, casual cruises, events, and such like that, but this is not an exclusive club and it's 100% free to join this site! So what are you waiting for? Register now!

I absolutely love that, however other than maybe rebuilding my stock axle the only fabrication i plan on doing involves a check and an ink pen. Don't have that kind of time or tools.
once there are funds and time available, this is my next project. . . . . dear joelio, i NEED you to continue to research this so i have a solution when the time comes.
buuuut, maybe if jon wasnt such a jerk, hed already have the research done
Jon and I have both done our share of research on this. S60 is the way to go when it comes to ET per dollar. Unfortunately its not the lightest, but he did save 8 lbs rotating weight by using the Strange S-trac over the Eaton True-trac so hopefully our dyno results will be more favorable than the typical S60.
Where do you source your parts and how does a newbie with no tools go about aligning/shimming things properly? I honestly trust my own work more than anyone but that doesnt mean i want to practice this 2 or 3 times before I get it right. But for $300 i could justify rebuilding mine.
[MENTION=3564]hoogiesngrinderz[/MENTION] - any info?
I plan on taking some form of action on this project around March/April so I've still got time to research.

oooh, thank you . It will be a while, but your info is definitely useful. Zero way to further minimize loss with rotating weight?

You could run a spool differential (thats a no-no on the street), and run drilled axles. Thats about it for rotating weight specifically. Also when people say 28 or 35 spline axle thats basically just the size of the axle. Smaller would be lighter, but also weaker. Stock 10 bolt axles are 28 spline.
As for Non-rotating weight (weight that wont affect the parasitic loss) you can cut quite a bit off by using a fabricated housing but those are $$$$.

Keep an eye out for deals, that's how I keep the cost low. Weeks, sometimes months of searching ebay and CL in my spare time.
I don't like to buy used cone style clutch posi's, not rebuildable and not worth building a test jig to see what the breakaway torque is. I don't mind buying used Torsen units for cars or Gov-Locs for very light duty trucks. I've never paid over $150 for a Torsen, and that came with 3.42 gears. A bearing/shim kit is about $100.
If you want to do a new gearset and a new carrier, that gets expensive. 3.73 AAM ring and pinion (OEM) run about $250, Summit brand runs about $160. 3.90 Motive gear is a bit over $200. A new Detroit TruTrac carrier is around $380.
When it comes to tools and know how, borrow them. A 0-75 in lb dial torque wrench is essential. I use a bearing splitter and a press for the pinion gear, I have the Napa machine shop pull carrier bearings off used units. I have a slide hammer to pull axle bearings. I then use a dial indicator with a magnetic base to set the lash.

dammit. . . .$ i could handle, $$$$ .. . .not so much.
but really, im glad that you guys have done the research and testing. the last couple posts in your thread made it look like you hadnt made up your mind yet, so i didnt go digging through it. this is why you guys are the best!

If these things didnt cost $3k a pop I would gladly give a spool a try. Its just not something i want to experiment with and then not like. I already tolerate cam surge, aggressive clutches, and loud exhaust and none of it bothers me so it wouldnt surprise me if a spool did OK in my car. The back end is a tin can anyway.

Well I kinda haven't made up my mind yet, but thats more financial than technical. I do have it narrowed down to an S60 or rebuilding the 10 bolt (and then breaking it again and buying an S60 )

I wish i had a video of my last autocross. I think the back end was loose 80% of the course. Maybe thats why its tired of my shit... Thanks for the info btw Michael.

I ended up ordering the s60 from CRP. I went with 3.73s, S trac (35spline), relocation brackets (now standard), 3 ch Abs, a chrome moly driveshaft, chrome moly yoke, and black powder coating. Should be a solid setup... I'll let you guys know how it comes out. It was killing me to add the extra weight but the fab 9s are over 1k more. I only expect the weight difference to be 10-40 lbs. I am gonna get a umi relocation bracket, and some m&h drag radials, should be fun! I'll keep you guys posted.
It's worth it if you have any interest in it. Now CornerCarvers... don't visit there unless you have an engineering degree and you can deal with a bunch of 50 year old toddlers.
