Why can't a 9" be used for daily driving?

it can, but a locker makes it somewhat awkward and if you dont go to the track that often you dont need all the strength it provides and money it consumes

I've been soaking up information like a parched sponge. I've decided to go with a Strange 12 bolt. Good reputation, easy to bolt up, and a remedy for the brake backing plate issue--->TByrne has a great idea. Kind of like a swap/core charge that's refundable.

In fact, he just started a GP on Strange Rears, and the price is right.

I did not read this entire thread so sorry if this is a repost.
Check out this article http://www.chevyhiperformance.com/t...cles/0304_nine/
I say nine inch. Too many on here have had problems with the 12 bolts. Especially in M6 cars. Then again if you have 3 channel ABS and want to keep it you can only do that with the 12bolt.

Thanks Brad. The link doesn't directly hook you up to the article, but I'll find it. Also, I'm only pushing 412/383 to the rear wheels and plan only to launch with Nittos. I do prefer to keep my ABS active too. Should I be ok? I do not plan to spray or do 6k dumps.

Yet.

I will say you should be okay as long as you stay away from the hard launches. Most of the problems (that I have seen on here) have been from guys breaking the posi. Most went with a spool afterwards. The nine inch is much stronger but eats about 2 to 3 % more power than the 12bolt. If you go with a posi in the nine inch it is prone to breakage as well. I went with a locker in my nineinch. It makes alot of noise but that is no problem for me.

You say only DRs and no 5-6k clutch dumps now. I will bet that you may be singing a different tune down the road though. Why not go with the stronger of the two to begin with. You could build a posi 3rd member for the street and a spool for the track. Or just run a locker and put up with the bangin an poppin when you turn.

All in all it depends on what you want to do with your car. I like to plan ahead. My rearend is definately overkill for now but in a year the car will be makin the power to warrant it.

Just my .02,
Brad

No unfortunately no one has come up with a setup to put a reluctor wheel on the ring gear of the nine inch. I am not sure about the 8.8 but it is very similar and not as popular so I would assume not.

Just when I made up my mind, I lost it again! The 8.8 Rear vendor offered me a decked out rear with ABS for $2100.00 shipped. I was previously going with a Strange 12 Bolt with TByrne for $2300.00 + shipping (with super-posi.)

Dayem, what to do??!!

I'd go with the 8.8 if I were presented with the same choices.

It's 3 channel.

Hmmmm, you'd take the 8.8". My hesitation is that it is a "small time" guy, so I don't know what kind of follow up/customer service will occur if I have issues. Also, I'm not too keen on PayPal, which is my only choice for the 8.8". May be I just don't know enough about PayPal.

TByrne has been doing this forever, and it appears that Strange has got a good rep. Shoot, I won't mind saving a few hundred dollars with the 8.8 either, that way I can buy DR's or a stronger clutch.

Still sitting on the fence..

I'm making my own 8.8 hybrid. Last night I cut the legs off the 10 bolt (tossed the center section) and the 8.8. I left 5" on either side of the 8.8's center section to slide, I presumed, the 10 bolts legs into these 5" stubs. I presumed that the smaller diameter 10 bolt legs would fit. Wrong The outter diameter of the 10 bolt legs are *just barely* too large for the inner diameter of the 8.8. Recovery looks to be to apply a reducer and TIG weld them together. I have the 8.8 carrier. I have the gears (4.10's) on order.
Taking the 8.8 center section and the legs to the welder on Friday.
