where the midwest one goes, theres plenty of room for exhaust to go under. You can tuck the cross bar up against the floor

It's more complex than that. I have MAC inner subframe connectors and then the 3.5" exhaust. It just would have required a ton of reworking on the car.

I bought a UMI crossmember/TA mount combo and have a UMI torque arm I'm going to give a try. The jegster torque arm had the typical clunk due to play in the slip joint and was driving me nuts with the manual trans.

Re: Who's 9" is the best deal ?

Moving along. Some photos and then some feedback..




Yes, my shop is full of crap.

Anyway. I don't normally dog on manufacturers but I'm getting kinda salty with Quick performance. I will say price wise they are the cheapest in the business, but there are a LOT of small things that I found quite annoying with them.

1) The LCA, shock mounts, spring cups are located in the wrong spot. They are moved inboard 3/8" per side. I called Quick and spoke to them a few times. I got some basic confirmation that "I see what you see" in regards to the fact that the spacing is off, yet they claimed "we sold 3700 of these and nobody has complained". The website says it works with factory suspension components. This is not 100% correct. I solved this problem by using new control arms with 3/8" offset bushings on the chassis side.
2) They didn't send me the torque arm adapter. I complained, they said they would send it out. 3 weeks later, I called yesterday and they had no notes about it. They said they would call me back. They did not. Now, I had no intention of using it because I think the design is crap, but I still paid for it and wanted it. Even if I just cut it up for something else. I ended up using the Moser/Trick torque arm adapter.
3) They appear to only own a 1/2" drill bit at Quick Performance. Every hole is drilled to 1/2". Why is this a problem? Well, for starters the LCA mounts should be 12MM, so you end up with some slop unless you tighten the bolts with no mercy. However, the shock mounts and panhard bar are supposed to be 9/16, so you have to drill those out to get the panhard bar bolt or shock mount studs to fit. Sure, you can use a 1/2" bolt for the panhard, but since the sleeve is 9/16, again, you'll get slop/banging and your rear end won't stay in alignment.
4) I ordered flush mount ends with sealed bearings. The instructions showed bearings with seals on the bearing race, yet I got different bearings with inner axle seals. Does this matter? I don't know, but when you put stuff in the box that doesn't match the instructions it's confusing and unprofessional. Also, they included 3 axle seals (only takes two) and a 4th oddball seal of a totally different size. No idea where that goes, it's smaller than the axle seals.
5) The bag the housing bolts, housing end bolts, and axle seals came in is labeled "FBODY PINION SEALS". Da fawk?



So anyway. I have some drilling to do, then I need to install the third member and axles. Given my experience with this, I probably should have went with Trick or Moser. I know midwest makes a great 9" as well, but the price was a bit much. Although, when you consider I ended up buying adjustable LCA's, offset bushings, adjustable panhard, and the Moser/Trick TA adapter ($265 alone), I probably didn't save much over a midwest 9".

Oh.. Quick Performance made it a point to tell me the owner is a 4th gen fbody fanatic who owns multiple fbodies. You'd think out of all the 9" axle packages they make, they would get the fbody one spot on wouldn't you?

Interesting. I know my buddy had run or still does run the quick rear. Dont recall him having issues but i think he likely has rod end style lcas with offset bushings so 3/8” likely doest make a difference

Re: Who's 9" is the best deal ?

That's why I got rid of my QP rear before I got too invested in it. It fit like crap. If I'm spending money I want it to fit beautifully

Probably didn't even notice, and just pried it into place. Though, the shock and PBR mount holes would have hung him up unless he used 1/2" shock tube studs and a 1/2" bolt for the panhard. I googled and I'm not the only one who has complained about those.

Now my sway bar hits the TA mount. wtf.




Guess I have to make some shims.

I also didn't consider the lower pinion on the 9" might cause a clearance issue with the exhaust...

Re: Who's 9" is the best deal ?

Oh no! The way it looks in the pic, it's not even close to fitting a shaft in there. I'm super happy w my moser but yeah it's tight. I also used a 3.5 inch aluminum drive shaft. That also had clearance issues. As loaded the suspension and got it sitting how it will rest when driving I actually gained a little clearance in a few spots.

My Umi torque arm also doesn't fit over the moser mount properly. The casting on the mount hits the welds before the holes even come close to lining up.

Do you guys typically use the inside or outside holes on the TA ? I have not run a regular style torque arm in 20 years.. Didn't realize they have four holes now lol.

As far as the exhaust goes, I guess worst case scenario I can cut and move it under the passenger floor pan. The car isn't lowered, so it shouldn't be an issue. I've actually been thinking of swapping the single 3.5" race muffler for a pair of 3" mufflers anyway to try and quiet the exhaust down a little. I don't understand how the hell a small cam 5.3 with iron manifolds can be so loud off boost.

Re: Who's 9" is the best deal ?

My spohn arm fit well and is on the holes that moved the arm closer to the drive shaft. Getting the rear in was filled w little issues. In the end it's worth it.
