Who has MWC 9"?

[BashamWS6]

alright. ive heard nothing but great things about these tanks.
i need a new rear end before i do anything upgrades...
i have all stock suspension...so i need to build it up this summer alog with my tranny...figured id start with the rear

i wont break 600HP most likely
and in a year or two ill have a TSP LS7 427 (iron or aluminum i havent decided---and it will probably stay stock besides minor bolt-ons) as long as financing goes as planned

i heard go wit Yukon gears because theyre more quite than Richmonds
3.70s? for bolt-ons?
PST 1000HP Driveshaft
Adj LCAs? PHB? Torque Arms?
or should i get these from UMI?
i want to keep a smooth ride...i heard these can get pretty rough

who has them and what options do you have or suggest on what i should get?

[silverWS6]

M6=4.10's You'll love it and never look back.

The MWC 9" comes with a torque arm already

You don't need adj. LCA's unless you plan on running a slick or larger tire and will need clearance between the tire and wheel well.

You do want LCA relocation brackets welded onto the axle housings.

I thought I already answered all of this in another thread you posted in???

what if i upgrade to 18s with street tires??

and you did answer. but i figure other inputs would help too

I'm sure they have different TA's just like UMI and other mfg's do for different exhaust set-ups.

I would run a full-length torque arm with a cross-member relocation mount to get it off the tail shaft of the transmission. This style is OE and will clear your exhaust set-up as well.

It never hurts to get anything "adjustable". You probably will not be using it though and will be adjusting the lower control arm length to the "stock" length to get your wheel centered in the wheel well.

[35th-ANV-SS]

Just so you know, the clearance with the torque arm and the floor pan of your car is non-existent when you have a 9" rear end.

You WILL need to massage the floor pan of your car to create your own clearance between the torque arm and underside of the car.

I have the MWC 9" and will be happy to answer what I can. I finished my install a couple of months ago and did almost the entire thing by myself lying on my back in the floor of my garage. Not bad at all and the only place I had to break out the BFH was to "mod" the inner fender wells to help clear the 315's.

Here's what I went with:
housing backbrace (do this- you can't bolt it on later, it is welded on)
additional Meziere rear side filler cap assy (makes it much easier to fill)
4 channel abs axle mod (only need this if you have ABS and TCS- otherwise if you only have the ABS in the housing get the 3-channel)
billet clutch type posi(rebuildable) (MWC recommended this over the others for mine since it was a daily driver- I was impressed since I'd asked for the more expensive one)
black powdercoating on the rear and red on componenets
PST 3.5" aluminum driveshaft(M6) (You can get a u-joint to adapt the stock driveshaft, but it'll still be a half-inch short)
chromemoly adjustable lca's and panhard (I went ahead and did this, you don't have to)
Short torque arm with ORY brace (they make one for stock exhaust and duals or you can go with a full length TA which comes with a new trans mount and you can purchase the ds loop seperately.)
completely assembled rearend ready to bolt-in
4.11 Yukon gear (Richmonds are noisy and overkill)

I can say that this was the best mod I've made to the car and everyone who sees it is in awe. It really is a work of art.

Here is the thread on mine with some pics:

^^^
already read it. great write up that made me decide to go with MCW
i think i agree on all but the Torque arm-id get the full length
and the PST 3.5" driveshaft is cheaper at KYSpeed isnt it?
and were looking at $4K+?!?

this makes me reconsider Moser...

[bberretta]

Mine was under $4k, but barely! The short TA and the solid mounts of the LCAs make for a rough ride, so if you want to keep with near to stock ride quality, go with the long TA and either stock LCA's or LCA's with rubber or poly bushings.

[bberretta]

BTW, I also went with 3-point sub-frame connectors (UMI) as well which I got from KYSpeed. As for the PST driveshaft, I ordered it from MWC just to make sure that I got the right length, which is longer than stock.

am i this bad at math or what? i mean i know i aced my finite final but seriously

[zmg00camaross]

I also have a MWC, Mine is more drag set up with drag brakes and narrowed and all, With a MWC there will be no massage of the floor pan because of the torque arm, MWC is the best true bolt in rear on the market. I sold my stamp 9 inch housing to buy his, My setup cost me 4K with out a $1100 3rd member which I built myself, But I bought wheels and the strange drag brakes and all that made it that price. Me and 2 other buddys bought from MWC and I have installed 3 of them and have a bunch of experience with MWC and Erics Fab rear. Just order parts from him last week haha, PM me if you have any questions and hopefully can get you set straight. Edit, I paid 400 for my driveshaft. Its all about the options you want that makes it cost, His base price for a rear is 2700 and that is with a torque arm with mount.

No, it's not that much. The TA is included with the rear, so there's no additional cost unless you want the addition of a Drive Shaft loop for the long TA. He gives a discount if you buy the LCA's and PHB from him-they are solid mounts and double adj- real nice ones, but they're about the same price as the singles from KYSpeed (who I highly recommend- bought a ton of stuff from him!) You won't need the ABS rings, just send them to MWC when you send your backing plates and caliper mounts- pull them off the axles and you're good to go and you'll save some dough. I bet the Yukon aluminum case is nice, but I just went with the Strange nodular one- sure it weighs more, but I'll eventually get another center for the track and that one will be built to the hilt. I think you can knock a few hundred off the cost you have there and get it to closer to $4k.

[BashamWS6]

yeah i bought my exhaust thru mark.
but you say its rough...so should i stay away from his LCAs/PHB and get some UMIs from mark?
and how much does MWC charge for the Driveshaft? KYSpeed charges 420
and would the Yukon center be better or just lighter?

[35th-ANV-SS]

Why do you need a housing backbrace?
