Gday guys,

Well spoke with another diff and gear company today.

Heres their opinion:

T5 housing with BA XR6 Turbo internals modified input shaft to fit to suit tunnel set up. This eliminates the world class and definantly would hold up behind the 302w even if i use the car on the track. The bell housing adapter is no problems as there a several offered by castlemaine rod shop in varied lengths so no dramas there.

9" LSD shorterned (from later model mustang) with commodore discs . The housing is the slim lined to allow for room requirements and the rear of the housing is rounded.

Now we are looking at a locker for the diff and i would be of course looking at a auto locker. I may think this maybe over kill...... i have heard there are some severe drawbacks such as understeer etc.... I have also heard it is quiet loud especially the Detorit Locker. They are really designed for a 4WD's is my understanding but i know alot of Drag cars use them as well as Nascars... for traction mostly in straight line.


Of course at the end of this then theres the suspension set up to do.....


What do you guys think opinions????

Cheers,

Al

The locker may give you a lot of clunking and banging from the rear end in regular street driving. It might be quite noticable since you are nearly sitting on top of it in a Cobra.

You could perhaps look at a torsen differential

Just get a recon. LSD centre for it. Will give best bang for buck and work really well for street and track work. Even the guys circuit and drag racing regulary(a few times a month), still use LSD's.

Don't even think about full time detroit locker. Apart from being against the law, your street driving pleasure will definitely be deminished.

I can still remember pushing a club members cobra with detroit locker. Turn the wheel slightly and it felt like someone had put the handbrake on. Really hard to push.

Detroit lockers are street legal, as they still retain differential function.
I think you are referring to a spool (either full or mini-spool). Spools lock both axles together and are a real pain on the street, besides being illegal. Spools are great on the strip - had one in the Torana - but general street driving will cause an axle to break eventually. Many circuit cars use spools (eg. V8 supercars) because they are predictable and tough....

oops, yeah sorry, was thinking of mini-spool.

On the Gold Coast a standard test by Transport authority is to perform a circle on full lock. If you can do that without fuss from the back wheels you pass, if not, you go in for a full inspection.

Regarding weight distribution on your DRB

My Weighbridge Ticket says 1140kg
Front 580kg
Rear 560kg

So unless you have some unusual setup I dont think weight is the problem for your rear end handling. Might be suspension?
