The angle of the axle is never extreme to the point where the car scrubs speeds. In the front, i get it, when the front wheels turn left and right and go up and down. But in the rear, really? If i just think of the physics, and how much a sedan's suspension moves, with the camber changes, and toe angles...
i agree. dcjs have more play in them then regular cvds. i would think they would hurt more than help. I can't see a benefit of them in the rear

Thats why I didn't quite explain it. It doesn't make full sense to me either. The only and I mean only thing i can think of is with the cvd's if enough pressure was applied it could technically bind at the right angle. The DCJ's would leave that free.

Thats all I got.

I think it gets rid of the little bind of the cvds as the suspension compresses. Little being the key word there. Assuming they are the same length as the cvds they replace.

Generally, the standard driveshafts will bind up slightly more. This prevents the suspension from compressing quite as much and putting all pressure or load to the tire. This increases forward traction when you are first accelerating and tends to lock the back end in more.

When DCJ's are applied to the back, the car's rear suspension is free to comply more and absorb the weight transfer, but it wont transfer that load to the tires for that short period of time when first accelerating out of the corner, thus providing slightly more rear rotation.

People forget there is a difference between load transfer and weight transfer. Load transfer implies that there is a transfer in force or load directly to the tires. Weight transfer results in a change of center of gravity due to body roll, or pitch changes.

don't forget the diff height!!

That happened to my towers also. I had to file the bottom edge that's close to the bulkhead. Once I did this, it fit right in easy.

Did you forget to add the 0.5 shim to remove the play?

Its not .5. But the shim will cause play as well. Make sure that you put in the proper screw with the proper screw head as well for the spur area. It actually pushes it out a little out as well.

How does the diff height affect the car's handling? the height of the diff affects the weight transfer, correct? I had to loosen my belts which meant raising my diffs a little

This makes a lot of sense, but i have to wonder if the rear moves enough to have that little bit of binding, with cars at 5mm from the ground, and it being an onroad car. I would have to test it to feel it.

Thank you for the clear input

I don't think you will notice it if the traction is lower. But if you look at almost all the high traction setups it lists dcj's in the rear

I didn't find the right combo set up with the T-shox the works for me compare the Yokomo stock springs ( mine short shock)
what piston hole size and wt. oil and springs did you have ?

Thats interesting to hear considering I don't think there is a car out there you haven't tried yet.
