If the Quaife ends up significantly cheaper, I'd probably go with it. Without knowing the rates of Don's it does make it a bit harder to choose also.

II'm not seeing significant lift with it right now, I will before its over with. I'll be itnerested to see how my new rear setup does though, my 325# springs should really spark some fire under that jerk. I'm thinking it needs to end up with something more like 350-500#/500-650# front/rear before it'll really get nasttty. Until then, I should have a prototype set of the adjustable control arms next week or so, and a nice solid front alignment should be a very gooood start to things.

I'm not sure how much this car will ever lift, being 3400-3500lbs and seeing as I'm not likely to easily fit much more than a wide 225 under it without significant mods that I'm just entirely too lazy to do.

What are you using for sway bars? Rear and front.

I had a Suretrac ATB fitted to my previous car and just short of 20,000 miles of road use (admittedly some hard driving and occassional track use), the gearbox developed a loud grinding noise which was determined to be the ATB. AP Racing told me (as has already been mentioned) that the ATB could not be repaired / rebuilt and was to be thrown in the bin and I'd have to buy a new one.

I have now bought a diff from Don at Kalmar-Union having spoken to several of his customers, one of whom is currently running 500+ whp without any reliability or traction issues, and several have been running high horsepower for some time.

Slater, I do race my car. As a matter of fact, I'm going to VIR with it in 48 hours. I'm signed up for atleast 2 or 3 autocrosses with it already also. And these are just the events that have registration open already.

OK then, I would recommend a clutch lsd for you.

IPD 25/22 right now. Haven't decided how I want to bar it, I'm still not sure what I think of the rear swaybar setup.

I have a rear IPD 22. I think its not big enough, all tho I'm just begining to play with springs and shocks.

My plan is to maybe cut the end off and slide a 4130 tube over it ( I'm thinking .095" wall) and weld / normalise it.

We'll see :)

This is why I kept the stock front bar. It will produce the same effect as a larger rear bar without the increased stress a larger rear bar would cause.

Didn't IPD used to have a 24 or 25mm rear and stopped selling it because of breakage problems? I seem to remember hearing about that a while ago.

I too kept the stock front bar for the same reason.

When you say stress, do you mean the stress that is breaking the IPD rear bars that i'm hereing about?

Just for conversation:

I've had a lot of experiance oval and road racing FWD cars and I found that NO front sway bar with stiffer front springs, coupled with stiff rear springs and a rear sway bar that is stiff enough to just barely not lift a rear wheel works best.

Now this is on 1900 to 2200# cars. So I have some learning to do on the heaver Volvo.

Yeah, I've been meaning to remove my front bar completely and seeing if I like the feel or not.

Guys, the Quaife LSD is custom ordered from Atech. I don´t think you can find them in the Quaife catalog.

I think you need to order 30 to get the custom made.

Edit: Didn´t read the whole thread, I may talk BS?

They may be custom orderd, but the reality is that they DID do whatever tooling is necessary to make the "Atech" one, and would have assigned it an internal part number. Lets say the internal part # for the "custom Atech" one is #11223. Well, we just want to have a group buy for #11223. They shouldn't require anything special to do it (apparently other than a 15 ordr minimum), since they already "make" or have made the part.

Peter @ Atech said he will be placing an order soon and asked how many units we're looking for. I have linked him to this thread. I explained that people need to know the pricing before they will commit. Hopefully he will make a post.

The pricing and what tranny's it will be compatible with (i.e. just M56 or AW50-42 as well) :) .
